Best eSIM for Canada From the UK: Plans, Networks and Roaming

If you’re travelling from the UK to Canada, the first thing I would check is what your current mobile plan already gives you.

EE, Vodafone UK, O2 and Three all handle Canada differently, and depending on your plan, roaming can be included, charged through a pass or billed by the day. For a short trip that may be perfectly fine. Over one or two weeks, those charges can start to make a separate travel eSIM much more attractive.

That is really what this guide is about: figuring out the best eSIM for Canada from the UK without ignoring the roaming option you already have.

I tested all eight eSIM providers in this guide in Canada: Airalo, Holafly, Vodafone Travel, Saily, aloSIM, BNESIM, Jetpac and GigSky. Depending on the provider, my testing covered Toronto, Montreal, Vancouver, Calgary, Edmonton, Ottawa, Quebec City, Niagara Falls, Saskatoon and Regina.

That gives me first-hand Canadian network and performance data to compare with current plans, features and UK roaming costs.

For many travellers, the best setup may actually be a combination of both: keep the UK SIM active for your normal number and use the Canada eSIM for mobile data.

If you want a broader comparison that is not specific to UK travellers, see my Best eSIM for Canada guide.

What Is the Best eSIM for Canada From the UK?

For most UK travellers, I would start with Airalo or aloSIM if you want a fixed-data plan, while Holafly is the more obvious option if unlimited data matters more than getting the lowest price.

Airalo performed extremely well in my Canadian testing and connected to Bell. aloSIM was also one of the strongest performers I tested and connected to Rogers, Bell, TELUS and SaskTel across my test locations.

Holafly is easier to understand if you simply want unlimited data for a set number of days, although its 1GB-per-day hotspot allowance makes it less attractive if you expect to tether a laptop heavily.

BNESIM is worth a closer look if you like the idea of non-expiring data, while Jetpac combines strong download results in my testing with useful hotspot support.

Saily is a straightforward app-based choice with fixed and unlimited plans, while GigSky stood out for the number of Canadian networks I encountered during testing.

Vodafone Travel eSIM is also worth comparing, particularly if your trip includes the United States. Just remember that Vodafone Travel eSIM is a separate travel product. It is not the same thing as roaming in Canada with your normal Vodafone UK mobile plan.

For many travellers, the most practical setup is not choosing between your UK SIM and a Canada eSIM at all. It is using both: keep the UK line active for your existing number and use the travel eSIM for Canadian data.

Canada eSIM Comparison for UK Travellers

The network entries reflect the Canadian networks I encountered during testing, supported where available by current provider information. They should not be read as a guarantee that every current plan will always connect to every listed network.

Airalo eSIM for Canada

Airalo is one of my strongest choices for a UK traveller who wants a conventional fixed-data Canada eSIM.

Current Canada options include smaller packages for short trips, larger fixed-data packages and unlimited plans. Airalo also has selected Canada packages that include cellular calls and SMS, so it is important to check the exact package rather than assuming every Airalo plan is data-only.

In my Canadian testing, Airalo connected to Bell.

I tested it in Toronto, Montreal, Old Quebec City, Ottawa, Vancouver, Calgary, Edmonton and Saskatoon. A practical middle-ground result from those tests was approximately 425 Mbps download, with 38 Mbps upload and 22 ms latency.

That was one of the strongest results in my Canadian testing.

Airalo also currently identifies Bell for its Canada service, so the network I observed lines up with its current public information.

For a normal one- or two-week UK trip, I like Airalo because you can choose a fixed allowance instead of automatically paying for unlimited data you may not need. For a broader look at the service beyond Canada, see my Airalo eSIM Review.

aloSIM eSIM for Canada

aloSIM is another strong fixed-data option, and it produced some of my best Canadian performance results.

I tested aloSIM in Toronto, Montreal, Vancouver, Edmonton, Niagara Falls and Regina. A representative result from those Canadian tests was approximately 414 Mbps download, with 65 Mbps upload and 63 ms latency.

I also saw the widest network mix of almost any provider in the test:

Rogers, Bell, TELUS and SaskTel.

There is an important distinction here. aloSIM’s current Canada information advertises Bell and TELUS, while my own testing also encountered Rogers and SaskTel.

That does not mean every aloSIM Canada plan currently has access to all four networks. It simply reflects what I observed during real Canadian testing.

aloSIM is primarily a travel-data product. Its calling and number option works through the separate Hushed service, so I would not describe that as a normal Canadian mobile number included directly with the travel eSIM.

For a UK visitor who mainly needs fast Canadian data and likes fixed-data plans with top-ups, aloSIM is one of the first options I would compare with Airalo. I cover its broader plan structure and setup in my aloSIM eSIM Review.

Holafly eSIM for Canada

Holafly takes a different approach.

Instead of making you decide whether you need 5GB, 10GB or 20GB, its Canada product focuses on unlimited data for a chosen number of days.

That can be convenient if you use your phone heavily and do not want to keep checking a data balance.

Holafly currently lists Bell and TELUS for Canada, which also matches the networks I encountered during testing.

I used Holafly in Toronto, Montreal, Old Quebec City, Saskatoon, Vancouver, Calgary, Edmonton and Niagara Falls. My representative Canadian download result was approximately 132 Mbps, with 24 Mbps upload and 55 ms latency.

That was slower than Airalo and aloSIM in my tests, but still more than adequate for normal travel use.

The bigger limitation is hotspot use. Holafly currently allows 1GB of data sharing per day on its Canada plan. That may be fine for occasionally connecting a tablet or laptop, but it is not the plan I would choose for several hours of laptop tethering every day.

Holafly’s Canada eSIM is also data-only. WhatsApp, FaceTime, iMessage and similar services work over data, but the eSIM itself does not give you a conventional Canadian mobile number.

I look more closely at how its unlimited-data model works in my Holafly eSIM Review.

BNESIM eSIM for Canada

BNESIM is one of the more interesting options if you dislike short expiry periods.

Alongside regular fixed-data packages, BNESIM offers non-expiring data, which can make sense if you expect to return to Canada or want data that does not disappear at the end of a short validity window.

BNESIM also performed well in my testing.

I used it in Toronto, Montreal, Saskatoon and Regina and recorded a representative download result of approximately 300 Mbps, with 59 Mbps upload and 85 ms latency.

The networks I encountered were:

Bell, TELUS and SaskTel.

BNESIM supports personal hotspot/tethering when the plan, device and local network conditions support it.

Its communication features require a little more explanation. The travel eSIM is primarily used for data, while BNESIM also operates separate voice and number services through its platform. I would not treat that as the same thing as buying a Canadian carrier eSIM with a conventional Canadian mobile plan.

BNESIM is not necessarily the simplest choice in this comparison, but its flexible and non-expiring data model gives it a genuine reason to be here. My BNESIM eSIM Review goes into more detail on how those flexible plans work.

Jetpac eSIM for Canada

Jetpac is particularly interesting if hotspot use matters.

Its current Canada range includes fixed-data and unlimited options, and Jetpac supports tethering. Its unlimited products use a daily high-speed allowance before speeds are reduced, so “unlimited” should not be read as unlimited full-speed data without conditions.

My Canadian Jetpac testing covered Toronto, Montreal, Vancouver and Saskatoon.

I recorded a representative download result of approximately 211 Mbps, with 32 Mbps upload. Latency was considerably higher at 132 ms.

Jetpac connected to Bell and TELUS during my testing.

That combination of strong downloads and relatively high latency is a good example of why I do not rank travel eSIMs using download speed alone.

Jetpac does not provide conventional SMS through the travel eSIM. It offers optional outgoing calling through in-app voice packs, which is different from having a normal cellular voice line.

For a traveller who expects to share data with a laptop or another device, Jetpac deserves a closer look. I cover its plan structure, setup and travel extras separately in my Jetpac eSIM Review.

Saily eSIM for Canada

Saily is a good fit if you prefer an app-first experience and want a straightforward choice between fixed and unlimited data.

Current Canada plans include smaller fixed-data packages through larger allowances and an unlimited option. On the unlimited plan, the full-speed allowance is subject to a daily threshold before data continues at a reduced speed.

Saily also supports hotspot use.

I tested Saily in Toronto, Montreal, Niagara Falls, Ottawa, Vancouver and Calgary. My representative download result was approximately 88 Mbps, with 22 Mbps upload and a relatively low 25 ms latency.

During those tests, I connected through Rogers and Bell.

Saily now also offers an optional phone-number feature with separate calling and SMS service. The important detail for a visitor to Canada is that this is a US number, not a Canadian mobile number.

If your goal is simply reliable mobile data with a polished app and some additional security features, Saily remains a practical option. My Saily eSIM Review covers the app, plans and broader travel experience in more detail.

Vodafone Travel eSIM for Canada

Vodafone Travel needs a little clarification for UK readers.

Vodafone Travel eSIM is not Vodafone UK roaming.

Vodafone Travel is a separate prepaid travel eSIM service. You do not need to move your UK mobile contract to Vodafone or use a Vodafone UK plan to buy it.

Its current Canada range includes fixed-data and unlimited plans, and the Canada product is data-only and 5G-ready. Vodafone Travel also offers a North America plan covering Canada, the United States and Mexico.

That regional plan is particularly relevant if your holiday includes both Canada and the USA.

I tested Vodafone Travel in Toronto, Montreal and Quebec City and connected through Rogers.

My representative Canadian download result was approximately 47 Mbps, with 12 Mbps upload and 128 ms latency.

That was substantially slower than Airalo, aloSIM and BNESIM in my tests.

That does not mean Vodafone Travel will always be slower. The tests occurred under particular network, location and routing conditions. It does mean I would not recommend it purely because the Vodafone name is familiar to UK travellers.

The regional plan and straightforward prepaid structure are stronger reasons to consider it.

For more of my testing and experience with the service, see the Vodafone Travel eSIM Review.

GigSky eSIM for Canada

GigSky produced a different kind of result in my testing.

Its download speed was not among the fastest, but I encountered Bell, Rogers, SaskTel, TELUS and Vidéotron across Toronto, Montreal, Vancouver, Calgary and Saskatoon.

That was the broadest network mix I observed among these eight providers.

My representative download result was approximately 88 Mbps, with 35 Mbps upload and 88 ms latency.

GigSky’s Canada service is data-only. It does not include conventional cellular calls or SMS, although WhatsApp, FaceTime and other VoIP or messaging apps work over its data connection.

Hotspot is supported.

GigSky also offers North America coverage that includes Canada and the United States, with Mexico included in its North America offering. That makes it worth considering for a cross-border itinerary.

I see GigSky more as a flexible alternative or backup than the automatic first choice for every UK visitor, but the Canadian network access I observed gives it a useful point of difference.

My Canada eSIM Test Results

I do not think a travel eSIM should be chosen from a speed test alone.

Still, testing these providers in Canada was useful because it showed how different the real connection can be even when two eSIMs use the same underlying Canadian network.

The download figures below are practical representative results derived from the Canadian measurements I recorded rather than guaranteed speeds. Performance can vary with location, network congestion, device, LTE or 5G availability, signal conditions and network routing.

Airalo and aloSIM produced the strongest representative download results in this group, while BNESIM was also fast. Jetpac delivered a solid download result but with considerably higher latency.

Vodafone Travel was noticeably slower in my tests, while GigSky’s main distinction was the range of Canadian networks I encountered rather than raw speed.

What Do Canada eSIMs Cost From the UK?

Travel eSIM pricing varies by data allowance, validity and whether you choose fixed or unlimited data. For a UK traveller, the useful comparison is what the eSIM costs for the trip versus what you would pay to keep roaming with your UK carrier.

The prices below show current Canada plans in British pounds and Canadian dollars. The converted amounts are approximate and can move with exchange rates or provider promotions.

The table converts each provider’s current selling price into GBP and CAD for easier comparison. Several providers price their Canada plans in USD or EUR, so the converted amounts may move slightly with exchange rates.

The plans are not all identical. Holafly’s price is for unlimited data rather than a fixed 5GB allowance, while Vodafone Travel is currently running a promotion that doubles its normal 10GB plan to 20GB and applies a 15% discount. Promotions can change.

GigSky’s figure is an entry price, not the price of a comparable 5GB plan. Its current public Canada page advertises plans from this level, so it should not be read as though GigSky is offering the same amount of data as the 5GB plans above for £2.91.

The cheapest plan is not automatically the best value. Also compare the data allowance, validity, fixed versus unlimited data, hotspot rules, Canadian network access, Canada + USA coverage, calls and SMS where relevant, and how much data you realistically expect to use.

This is where the difference with UK roaming can become substantial. At O2’s current £7 daily rate, seven chargeable days would cost £49, while fourteen chargeable days would cost £98. Several fixed-data eSIMs above cost considerably less than that for the whole plan.

That comparison changes completely if Canada is already included with your UK mobile plan, so check your existing roaming benefits before buying another service.

Canada eSIM vs UK Roaming

A travel eSIM is not automatically the right choice just because you are going abroad.

Your existing UK carrier may already include Canada, or a roaming pass may be worth paying for if you want the convenience of using your normal number, calls, texts and data exactly as you do at home.

The first thing I would do is check the roaming benefits attached to your specific UK plan.

The important point is that there is no single roaming price that applies to every customer of each UK carrier. Older contracts, premium plans, included roaming benefits and current plan families can produce different costs.

O2 Roaming in Canada

O2 currently includes Canada among the destinations available through its O2 Travel options.

For customers who need the standard O2 Travel Bolt On, the current rate is £7 per chargeable day. That gives you unlimited data, minutes and texts, with mobile-data speeds capped at up to 2 Mbps.

A chargeable day is a day when you actually use the O2 line abroad. The £7 charge is triggered if you use mobile data, make a call or send a text. Simply receiving a call or text does not trigger the O2 Travel daily charge.

O2 calculates the daily period from midnight to midnight using the local time of the capital city in the country you are visiting.

If you triggered O2 Travel on:

• 7 chargeable days, the total would be £49
• 14 chargeable days, the total would be £98

That is more useful than assuming that a seven-day holiday automatically means seven daily charges. If you keep your O2 line active only to receive incoming texts and use a Canada eSIM for mobile data, you may not trigger O2 Travel every day.

There is another important exception. Some current O2 plans already include Canada through an O2 Travel Inclusive Zone benefit, including eligible Plus and Volt arrangements, while O2’s Ultimate Plans include Canada through the larger Travel Inclusive Zone Ultimate.

Those eligible plans include roaming data, minutes and texts in Canada without the standard £7 daily Bolt On charge, although O2 applies a 2 Mbps data-speed cap to its Inclusive Zone service.

So do not assume that every O2 customer should budget £7 per day for Canada. Check your exact plan in My O2 before buying a travel eSIM. If Canada is already included, the cost comparison can look completely different.

Three Roaming in Canada

Three includes Canada in its Go Roam Around the World Extra group. This lets eligible Pay Monthly customers use their UK calls, texts and up to 12GB of their data allowance while in Canada.

How much it costs depends on your plan and when you joined or last upgraded. Three currently lists a £7 daily roaming charge for many customers who joined or upgraded between October 1, 2021 and December 17, 2025. For customers who joined or upgraded on or after December 18, 2025, the current daily charge is £8 from April 1, 2026. Some plans also include Go Roam passes, and you can buy Around the World Extra passes separately instead of paying the daily rate each time.

The 12GB roaming limit is worth checking if you use a lot of data. Even if your UK plan includes considerably more than 12GB, Three normally limits Pay Monthly Go Roam usage to 12GB of data while abroad under its fair-use rules.

For a longer Canada trip, compare the cost of your available Three pass or daily charges with a prepaid Canada eSIM. If roaming is already included with your plan, Three may be the easier option. If you would otherwise pay £7 or £8 repeatedly during a one- or two-week trip, a separate travel eSIM can be considerably cheaper.

Vodafone UK Roaming in Canada

Vodafone UK uses a zone-based roaming system, and the amount you pay in Canada depends on your specific Pay Monthly plan and when it started.

For many current plans, roaming in the applicable worldwide zones costs £8 per day from April 14, 2026. That daily charge lets you use your UK allowance for calls, texts and data while roaming, subject to the terms and limits of your plan. Vodafone’s current charges guide lists £8 per day for Zone C or D roaming.

The daily fee is usage-based rather than simply being charged because you are physically in Canada. Vodafone applies the roaming charge when you use the line for activity such as mobile data, making calls or sending texts. Receiving calls is currently listed as free under the relevant Pay Monthly roaming charges.

Older Vodafone contracts and plans with roaming benefits can work differently. Vodafone currently says that customers travelling to a destination not included in their plan may either add an available roaming Extra or pay the applicable daily charge. That is why I would check Canada in the Vodafone Roaming Charge Checker against your exact plan before assuming you will pay £8 every day.

If you would trigger the £8 charge on seven days, that would be £56. Fourteen chargeable days would reach £112. At that point, a prepaid Canada eSIM can be considerably cheaper if mobile data is your main requirement.

And remember that Vodafone UK roaming and Vodafone Travel eSIM are completely separate products. Vodafone UK roaming uses your existing UK Vodafone line and allowance in Canada. Vodafone Travel is a prepaid travel eSIM that can be purchased independently, even if Vodafone UK is not your home carrier.

EE Roaming in Canada

EE treats Canada as a Rest of World Zone 1 destination for current Pay Monthly roaming. If your plan does not already include Canada, EE currently offers a 24-hour pass for £6 or a 7-day pass for £30, both of which let you use your UK plan allowance while roaming.

That makes the weekly pass important for a longer trip. Seven separate 24-hour passes would cost £42, while the 7-day pass costs £30.

Some EE plans already include Canada. Current Full Works plans include Rest of World Zone 1 roaming, including Canada, with a 50GB fair-use limit while roaming. If you have one of those plans, buying a separate travel eSIM may be less compelling unless you want another Canadian network or backup data.

For everyone else, compare the cost of the EE pass you would actually need with a prepaid Canada eSIM. A £30 weekly pass can be competitive for a short trip, but over two weeks that becomes £60, while several fixed-data Canada eSIMs in this article cost well under £20.

When UK Roaming Still Makes Sense

I would not buy a travel eSIM automatically.

Using your UK carrier can still be the better option when:

• Canada is already included in your plan
• your trip is only a couple of days
• you need conventional calls and SMS on your normal UK number
• your employer is paying the roaming bill
• you want the simplest possible setup
• the difference in cost is small enough that convenience matters more

If your plan gives you Canada roaming at no extra cost, there is little reason to buy another eSIM unless you want backup connectivity or another network.

The calculation changes when you are paying £7 or more for every roaming day. Over a one- or two-week holiday, a prepaid data eSIM can become much cheaper.

Which Canadian Network Does Your eSIM Use?

Canada’s major national mobile networks are Rogers, Bell and TELUS, with other important regional networks including Freedom Mobile, SaskTel and Vidéotron.

For a visitor, the network matters because Canada is geographically enormous.

A plan that works perfectly in downtown Toronto does not guarantee uninterrupted service on a mountain highway in Alberta or a long rural drive in Saskatchewan.

My own tests also show why the network name is only part of the story.

Airalo and Holafly both used Bell during parts of my testing, for example, but they did not produce identical performance. Routing, roaming architecture, congestion and the eSIM provider’s own arrangements can all affect the connection.

The same principle applies when an eSIM can access multiple Canadian networks.

Do not assume a list of four networks means your phone will freely switch among all four everywhere you travel. The actual network available to your plan can vary.

Using an eSIM in Toronto, Montreal, Vancouver and Calgary

For a normal city-based trip, I would worry less about finding a provider with the longest possible network list and more about choosing the right data allowance, hotspot policy and plan duration.

I tested multiple providers successfully in Toronto, Montreal, Vancouver and Calgary.

These are major Canadian urban areas served by the country’s large mobile networks. For most visitors, the practical differences between travel eSIMs are more likely to involve plan structure, routing, speed, latency and features than whether you can get any mobile service at all.

That changes when you leave the major cities.

What Changes in Banff, Jasper and on Canadian Road Trips?

Canada’s size matters.

If you are driving from Calgary into Banff, continuing through the Rockies, travelling toward Jasper or spending significant time outside major urban areas, check coverage for the route, not just the city where you are sleeping.

A travel eSIM cannot create service where its underlying Canadian network has no usable signal.

Mountain terrain can also produce abrupt coverage changes. You may have a strong connection in a town and little or no service farther along the highway.

For a Rockies or rural itinerary, I recommend downloading important information before driving:

• offline Google Maps or Apple Maps areas
• accommodation addresses
• reservation confirmations
• park information
• tickets
• important phone numbers
• driving directions for remote stops

Network flexibility can help, but it should not replace offline preparation.

Canada and USA: Should UK Travellers Buy a North America eSIM?

If your trip includes both Canada and the United States, check regional plans before buying a Canada-only eSIM.

Airalo, Vodafone Travel, Saily, aloSIM, BNESIM, Jetpac and GigSky all have regional options that can make cross-border travel easier.

Vodafone Travel, for example, sells a North America eSIM covering Canada, the United States and Mexico. GigSky also offers North America coverage across Canada, the USA and Mexico.

The advantage is convenience. You can cross the border without buying and installing another eSIM.

That does not automatically make a regional plan cheaper. Compare the data allowance, validity and price with the equivalent Canada-only plan before buying.

If most of your holiday is in Canada and you are only spending one day in the United States, two separate plans may still cost less. For a genuine Canada-USA road trip, one regional eSIM is often easier.

If both countries are a meaningful part of your itinerary, my Best eSIM for Canada and USA guide compares eight regional options using my first-hand speed and network testing in both countries.

How to Keep Your UK SIM Active in Canada

One of the best reasons to use an eSIM is that you do not necessarily have to remove or disable your UK line.

On a compatible Dual SIM phone, you can keep your EE, Vodafone, O2 or Three line active while assigning mobile data to the Canada eSIM.

That can be useful for:

• receiving UK verification texts
• keeping your usual number reachable
• maintaining iMessage or other account associations
• receiving important bank or account messages
• using the travel eSIM for Canadian data

The key is configuring the two lines correctly.

A practical Dual SIM setup

Set the travel eSIM as your mobile-data line.

Keep your UK SIM as the line for your existing number, calls and SMS if you still need them.

Turn data roaming off on the UK line unless you intentionally want to use your UK carrier’s roaming data.

If your phone has an automatic cellular/mobile-data switching option, consider turning it off so the phone does not unexpectedly move mobile data back to your UK SIM.

Many travel eSIMs work through international roaming agreements, so you may need to turn data roaming on for the travel eSIM itself.

That sounds contradictory, but the two settings apply to different lines:

UK SIM: roaming data off.

Travel eSIM: roaming on when required by the provider.

On iPhone, Apple lets you choose the cellular-data line separately from your voice lines. Supported Android phones, including current Google Pixel and Samsung Galaxy models, offer similar Dual SIM controls, although menu names vary.

Receiving an SMS on your UK number is also different from using roaming data. Your UK carrier’s rules still apply to calls, outgoing messages, voicemail and other roaming activity, so check those charges before relying on the line abroad.

Before buying, you can use the eSIM Compatibility Checker to confirm whether your phone supports eSIM and whether carrier locking could be a problem.

Do UK Travellers Need a Canadian Phone Number?

Most UK tourists do not need a Canadian mobile number.

If you use WhatsApp, iMessage, FaceTime, Messenger, email and other internet-based services, a data eSIM can cover most everyday travel communication.

But a Canadian number becomes more useful if you need conventional local calls or SMS, are staying for an extended period, or need a local contact number for work or other Canadian services.

This is where travel eSIM terminology can become confusing.

Data-only travel eSIM

Provides mobile internet but no conventional mobile number.

Holafly, Vodafone Travel and GigSky are examples of data-focused products in this comparison.

Travel eSIM with cellular calls and SMS

Some travel providers now sell selected plans with conventional voice and SMS.

Airalo has Canada packages where calls and texts are included, so check the exact package rather than assuming every Airalo eSIM works the same way.

App or third-party number

This can provide calling or messaging features but is not the same thing as a Canadian carrier mobile line.

aloSIM’s Hushed arrangement and Jetpac’s in-app voice service are examples of why this distinction matters.

Saily’s optional calling/SMS service currently provides a US number, not a Canadian number.

Canadian carrier mobile service

If you genuinely need a regular Canadian number with conventional calls and SMS, a prepaid or monthly Canadian carrier plan may be a better fit.

That is a different decision from choosing the best travel eSIM for mobile data.

How Much Data Do UK Travellers Need in Canada?

For a normal UK holiday, you probably need less data than an unlimited-plan advertisement suggests.

A traveller using maps, WhatsApp, email, transit apps, restaurant searches and occasional social media can often manage comfortably with a fixed-data plan.

A rough starting point is:

The biggest variables are video and hotspot use.

Google Maps and messaging generally use relatively little data. Streaming video, uploading large files, video calls and tethering a laptop can use far more.

If you are unsure, I prefer a provider with straightforward top-ups rather than buying far more data than you are likely to use.

For a broader tourist-focused comparison, see Best Canadian eSIM Plans for Tourists.

Set Up Your Canada eSIM Before Leaving the UK

Install your eSIM while you still have reliable Wi-Fi in the UK.

You normally do not need to start using the plan immediately. The exact activation rule varies by provider, so check when the validity period begins before switching the line on.

Before your flight:

1. Confirm that your phone supports eSIM and is unlocked.
2. Buy the plan for the correct destination or region.
3. Install the eSIM using the provider’s app, QR code or setup instructions.
4. Give the new line an obvious label such as Canada Data.
5. Keep your UK SIM installed if you need your regular number.
6. When you arrive, select the Canada eSIM for mobile data.
7. Enable data roaming on the travel eSIM if the provider requires it.
8. Keep data roaming disabled on the UK line unless you deliberately want UK roaming.

Do not delete the eSIM just because it does not connect immediately. Some travel eSIM profiles cannot simply be reinstalled after deletion.

If you arrive and the eSIM connects to a network but mobile data does not work, use the eSIM Troubleshooting Guide before removing the profile.

Final Thoughts

The best way to stay connected in Canada from the UK depends first on what your existing UK plan already gives you.

If EE, Vodafone UK, O2 or Three already includes Canada at little or no extra cost, using your normal line can be worth it for the convenience.

If you would otherwise pay a daily roaming charge for one or two weeks, a travel eSIM becomes much more attractive.

From the eight providers I tested, Airalo and aloSIM stand out for fixed-data use and strong Canadian performance, while Holafly is the simpler choice when unlimited data matters more than price or heavy hotspot use. BNESIM is interesting for flexible non-expiring data, and Jetpac is worth considering when tethering matters.

For many UK travellers, I would use a hybrid setup: keep the UK SIM active for the number you already have, turn off its data roaming, and use the Canada eSIM as the mobile-data line.

That gives you Canadian data without completely disconnecting your UK number, while avoiding the need to depend on expensive daily roaming for everything.
