This Firsty eSIM review looks at what makes the provider different: eligible travellers can watch advertisements to unlock basic mobile data without buying a plan. For Canadians who mainly need messaging, directions, email, or a ride after landing, that free connection can be genuinely useful.
The compromise is speed. Firsty Free is designed for essential travel tasks, not video streaming, large downloads, heavy social media use, or reliable hotspot work. Travellers who need a faster everyday connection will likely be better served by Firsty Classic or the day-based Unlimited option.
I see Firsty Free as an arrival-day or backup connection rather than the primary data plan for an entire trip. The better option depends on how long you are travelling, how much data you use, whether you need hotspot access, and whether your Canadian number must remain active.
Firsty eSIM is worth considering if you want one reusable travel eSIM with a no-cost backup option. Firsty Free suits light, essential use, Classic is better when you want a fixed high-speed allowance, and Unlimited is the stronger choice for heavier daily use or hotspot access. For most Canadians, the free tier makes more sense as a backup or arrival-day connection than as the only data plan for an important trip.
Firsty eSIM Review at a Glance
| Review Point | Firsty Details |
|---|---|
| Best feature | Free, advertisement-supported basic mobile data |
| Best for | Backup access, arrival-day data, light users, and travellers who want one reusable eSIM |
| Paid options | Classic fixed-data bundles and Unlimited day-based access |
| Supported destinations | Firsty currently advertises service in 170 countries |
| Free-tier speed | 256 Kbps on the current Firsty Free plan page |
| Classic data | Bundles from 0.5 GB to 50 GB, valid for 30 days after activation |
| Unlimited policy | 5 GB at full speed per 24 hours, then 512 Kbps until the next cycle |
| Hotspot | Supported on Classic and Unlimited |
| Phone number | Best treated as a data line, with optional app-based international calling credits |
| Main limitation | Free access is deliberately slow and requires watching advertisements |
Firsty’s current public plan pages use the names Free, Classic, and Unlimited. Older help pages and reviews may still mention legacy options such as Comfort+ or First Class, so travellers should rely on the plans shown in the current app and checkout flow.
What Is Firsty eSIM and How Does It Work?
Firsty is an app-based global eSIM service built around one reusable eSIM profile. Instead of purchasing and installing a different eSIM for every country, you install Firsty once and then choose Free, Classic, or Unlimited access when needed.
Firsty currently advertises availability in 170 countries. The eSIM connects through partner mobile networks in the country you are visiting, so the local carrier, available network technology, congestion, and signal strength can still affect performance.
This one-eSIM approach is useful for travellers who take several trips each year or cross between countries. You do not have to keep searching your phone for expired destination profiles, although you should still confirm that Firsty supports every stop on your itinerary before relying on it.
Firsty is best treated as a travel-data service rather than a replacement for a complete Canadian mobile plan. The eSIM can handle internet-based messaging, maps, browsing, and other data use, while your regular Canadian SIM or eSIM can remain active for your phone number, conventional calls, SMS, and verification codes. Firsty also sells separate app-based international calling credits.
Firsty Free Review: What Do You Actually Get?
Firsty Free lets eligible users watch an advertisement to unlock 30 minutes of internet access at 256 Kbps. Watching more advertisements provides additional access time. Firsty positions the free service for WhatsApp, email, navigation, Uber, and other essential tasks rather than streaming or large downloads.
That speed is slow by modern mobile standards, but speed must be judged against the purpose of the plan. A connection at 256 Kbps may still be enough to:
- Send text-based WhatsApp or iMessage conversations
- Check email
- Load basic directions
- Request an Uber or another rideshare
- Look up an address or reservation
- Contact a hotel
- Access a boarding pass already stored in an app
It is not a good match for:
- High-quality video
- Large app updates
- Cloud backups
- Image-heavy social media feeds
- Video calls
- Remote work that depends on a stable hotspot
- Uploading many photos or videos
- Fast browsing across media-heavy websites
The best use case is easy to picture. You land in an unfamiliar airport, the public Wi-Fi is not working properly, and you need directions or a ride. Watching an advertisement to unlock a basic connection is far better than having no data at all.
The free tier becomes less attractive when connectivity is important rather than merely convenient. I would not depend on advertisement-supported access for a business trip, a same-day rail connection, a long road trip, or a family vacation where several people rely on one phone.
Firsty’s current Free page lists North America among the eligible user regions, making the offer relevant to Canadian users. Availability and the exact in-app experience should still be confirmed before departure.
Firsty Plans and Pricing
Firsty currently separates its service into three clear levels. Free provides basic advertisement-supported access, Classic provides a fixed high-speed data bundle, and Unlimited provides day-based service with a high-speed fair-usage allowance.
| Firsty Plan | Current Structure | Best For | Main Limitation |
|---|---|---|---|
| Free | No purchase required; one advertisement unlocks 30 minutes at 256 Kbps | Arrival-day access, messaging, maps, email, rideshares, and backup connectivity | Slow speed, advertisements, and limited suitability for media-heavy use |
| Classic | 0.5 GB to 50 GB; 30 days to use the bundle after activation; highest available speed | Travellers who know approximately how much high-speed data they need | Fixed allowance can run out |
| Unlimited | From €2 per day on longer trips; 5 GB at full speed every 24 hours, then 512 Kbps | Heavy phone use, streaming, downloads, longer trips, and hotspot use | “Unlimited” includes a daily high-speed threshold |
Firsty says larger Classic bundles can cost as little as €0.98 per GB, while Unlimited starts from €2 per day on longer trips. Using an approximate exchange rate of C$1.60 per euro, those figures are roughly C$1.57 per GB and C$3.20 per day before card conversion fees. The actual package total depends on bundle size or trip length.
Firsty Classic
Classic is the most balanced Firsty option for many travellers. You choose a bundle between 0.5 GB and 50 GB, activate it when needed, and receive 30 days to use it. Firsty says Classic uses the highest available network speed and supports streaming, downloading, and hotspot use.
A small Classic bundle may suit a weekend trip with moderate messaging and map use. A larger bundle is more appropriate for a longer stay, daily social media use, navigation, video calls, or occasional laptop tethering.
The 30-day period starts when the bundle is activated rather than when it is purchased. That makes it possible to buy before leaving Canada without immediately consuming the validity period.
Firsty Unlimited
Unlimited is the stronger option when you do not want to manage one fixed data bucket. Firsty provides 5 GB at full network speed during each 24-hour cycle. After that amount is used, service continues at 512 Kbps until full speed resets in the next cycle.
Five gigabytes per day is generous for normal phone use, but heavy laptop tethering, cloud syncing, large downloads, or extended high-definition streaming can reach the threshold. The reduced connection remains usable for lighter tasks, but it will feel substantially slower.
Firsty also lets users pause unused Unlimited days and resume them during a later trip. That flexibility is valuable for travellers whose itinerary contains time at home, cruise days, long Wi-Fi stays, or gaps between destinations.
Important: Firsty pricing, plan availability, exchange rates, supported countries, data allowances, speed policies, hotspot rules, advertisement requirements, and calling rates can change. Canadian-dollar costs will depend on the exchange rate and may not include foreign-exchange or card fees. Confirm the final details in the Firsty app before purchasing or activating a plan.

How Firsty eSim Coverage and Network Switching Work
Firsty’s main coverage advantage is that the same eSIM is designed to work across its supported country list. Classic and Unlimited are also marketed with the same euro pricing in each supported country rather than destination-specific rates.
That does not mean performance will be identical everywhere. Firsty relies on local partner networks, and the quality of those networks changes by country, city, rural area, building, airport, and time of day. A strong partner network in central London does not guarantee the same experience on a remote island or mountain road.
Firsty says its app searches for an available partner network automatically. If a connection is weak, the cause may be local coverage, congestion, incorrect mobile-data selection, disabled roaming on the Firsty line, or a network-selection issue.
Before buying a paid plan, check the destination through Firsty and compare alternatives in the eSIM Providers by Country directory. A multi-country traveller should verify every stop, including short layovers and side trips, rather than checking only the main destination.
Installing and Activating the Firsty eSIM
Firsty uses an app-led setup process. You download the app, create an account, select a plan, and follow the eSIM installation prompt on your phone. A stable internet connection is required during installation.
Before starting, confirm that:
- Your exact phone model supports eSIM
- The phone is unlocked
- You have reliable Wi-Fi or another working data connection
- Your phone software is reasonably current
- You know which line is your Canadian line and which will be Firsty
Use the eSIM Compatibility Checker before installing if you are unsure about your model, purchase region, dual-SIM support, or carrier-lock status.
Setting Up Firsty eSIM on an iPhone
After the Firsty eSIM is installed:
- Open Settings.
- Tap Cellular or Mobile Service.
- Label the new line Firsty or Travel.
- Keep your Canadian line selected for the default voice line.
- Keep your Canadian number selected for iMessage and FaceTime when prompted.
- Select Firsty as the mobile-data line.
- Turn off Allow Cellular Data Switching.
- Open the Firsty line and enable Data Roaming when required by Firsty.
Firsty advises using the primary line for regular calls and texts while assigning the Firsty eSIM to mobile data. Turning off cellular-data switching helps prevent the phone from silently moving data back to the Canadian line.
Setting Up Firsty eSIM on Android
Android menus vary by manufacturer, but the normal path is:
- Open Settings.
- Tap Network & Internet, Connections, or SIM Manager.
- Confirm that the Firsty eSIM is turned on.
- Select Firsty for mobile data.
- Keep the Canadian line selected for calls and SMS when needed.
- Turn off automatic mobile-data switching.
- Enable data roaming on the Firsty line.
- Restart the phone if Firsty does not connect after the settings are saved.
Do not delete the Firsty eSIM simply because activation is taking longer than expected. A deleted eSIM may require support assistance before it can be restored.
Firsty Speed, Hotspot Use and Everyday Performance
Firsty does not provide one universal speed because the result depends on the selected plan and local partner network. The clearest way to assess performance is to separate the deliberately restricted Free tier from the high-speed paid plans.
Firsty Free at 256 Kbps
At 256 Kbps, patience is required. Text messages and basic emails should use little data, but images, media previews, map tiles, and modern websites may load slowly.
Google Maps navigation is one of the stronger use cases because standard navigation generally consumes far less data than streaming or social media video. Downloading offline maps before leaving Canada will make the free connection more practical and reduce how much information must load while travelling.
WhatsApp text conversations and voice notes are also relatively light. Video calling is a different story because it uses far more data and needs a faster, steadier connection.
Firsty Classic at the Highest Available Speed
Classic is not intentionally restricted to the Free tier’s basic speed. Firsty says it connects at the highest available speed supported by the local partner network and conditions. It also promotes Classic for streaming, downloading, and hotspot use.
This is the better starting point when you need ordinary travel-data performance without buying a day-based unlimited plan. The actual result may still vary with destination coverage and congestion.
Firsty Unlimited and the Daily High-Speed Threshold
Unlimited also uses the highest available speed, but the full-speed portion is limited to 5 GB in each 24-hour cycle. Once that threshold is reached, service continues at 512 Kbps until the next cycle.
For most phone users, 5 GB in one day is substantial. The travellers most likely to reach it are those using a phone as a laptop hotspot, streaming video for several hours, downloading large files, backing up photos, or running software updates.
Does Firsty Support Hotspot Use?
Firsty supports hotspot use with Classic and Unlimited. Classic deducts tethered data from the purchased allowance, while Unlimited hotspot activity counts toward the 5 GB daily high-speed amount.
Firsty Free should not be selected specifically for hotspot use. Even where tethering technically connects, 256 Kbps is too slow for most laptop work, and travellers who need smoother streaming or large downloads should consider paid access.
Calls, Texts and Keeping Your Canadian Number Active
The Firsty eSIM should be treated primarily as a data line. It is not the same as moving your Canadian mobile number to another full-service carrier.
Firsty offers optional international calling through its app. Users add calling credit, see the per-minute rate before placing a call, and can display their own number to the recipient. Calling credits are separate from the mobile-data plan.
For incoming Canadian calls, regular SMS, voicemail, and verification codes, keep your Canadian SIM or eSIM active. Set Firsty as the mobile-data line and leave mobile-data switching off.
Keeping the Canadian line active does not automatically make every carrier action free. Depending on your carrier and plan, answering a call, making a call, checking voicemail, sending a text, or allowing the Canadian line to use mobile data may trigger roaming. The safest hybrid setup is to use Firsty for data and reserve the Canadian line for the specific number-based functions you need. See the full guide to using a travel eSIM instead of international roaming before departure.
Who Is Firsty eSIM Best For?
Travellers Who Want Free Backup Data
Firsty Free is a strong backup option because it can provide a basic connection without purchasing a package. It may solve the immediate problem of finding a hotel, loading directions, sending a message, or requesting a ride.
This is Firsty’s clearest advantage over providers that require a purchase before any mobile data becomes available.
Light-Data Travellers
A traveller who mainly uses hotel Wi-Fi and only needs occasional mobile access may find the free tier sufficient. The experience will be slower, but the cost is difficult to beat.
The compromise becomes less reasonable when the trip includes frequent navigation, media uploads, video calls, remote work, or long periods away from Wi-Fi.
Travellers Who Want One Reusable eSIM
Installing one eSIM for multiple trips is convenient. Firsty may suit people who travel several times per year and do not want to install a new destination profile every time.
This also makes Firsty useful as a permanent backup even when another provider is selected as the primary data plan.
Travellers Who Want Predictable Fixed Data
Classic is the most sensible Firsty choice when you know approximately how many gigabytes you need. It avoids advertisements, runs at the highest available speed, supports hotspot use, and gives you 30 days of validity after activation.
Heavy Users and Hotspot Travellers
Unlimited makes more sense for travellers who stream, work remotely, tether a laptop, or do not want to manage one trip-wide data allowance. The important detail is the 5 GB daily full-speed policy.
Travellers Who Need a Complete Local Mobile Service
Firsty is less suitable when the main requirement is a local phone number, conventional incoming calls, standard SMS, or a long-term domestic mobile account. In that situation, a local carrier plan or full-service SIM may be a better match.
Firsty eSIM Strengths and Limitations
| Strengths | Limitations |
|---|---|
| Free basic-data option | Free speed is limited to 256 Kbps |
| One reusable eSIM across supported destinations | Watching advertisements adds friction |
| Clear Free, Classic, and Unlimited choices | Local performance depends on partner networks |
| Classic bundles from 0.5 GB to 50 GB | Classic expires 30 days after activation |
| Highest available speed on paid plans | Unlimited has a 5 GB daily full-speed threshold |
| Hotspot supported on Classic and Unlimited | Not a replacement for a complete Canadian phone plan |
| Unlimited days can be paused | Regular SMS and Canadian-number functions still rely on your main line |
| Optional app-based international calling | Checkout is priced in euros, creating exchange-rate considerations |
Firsty’s strongest feature is not simply that it has a free plan. The bigger advantage is that the free connection remains available as a fallback around the same reusable eSIM that supports paid upgrades.
Its main weakness is also clear. The free connection is designed to prevent complete disconnection, not to recreate a normal high-speed mobile plan.
Firsty eSIM Alternatives
Firsty is unusual enough that the best alternative depends on which part of its service appeals to you.
The Roamless eSIM Review is the closest place to start if you like the idea of one reusable global eSIM but would rather pay according to actual data use instead of watching advertisements. Roamless FLEX uses non-expiring purchased credits, while its FIX plans provide defined data allowances for travellers who want more predictable usage. That makes Roamless especially relevant for repeat travellers, short trips, stopovers, and backup data.
For travellers who want a large selection of local, regional, and global fixed-data plans, the Airalo eSIM Review is a better starting point. Airalo does not offer Firsty’s advertisement-supported fallback, but it provides more destination-specific plan selection.
Travellers who prefer a straightforward paid app experience without managing a free tier may find the Saily eSIM Review more useful.
When unlimited-style destination plans are the priority and you are willing to pay more for simplicity, the Holafly eSIM Review is more relevant.
Use the eSIM Plan Comparison Tool to compare current plans by destination, approximate Canadian price, data amount, validity, and hotspot support. The tool does not replace Firsty’s current checkout, so confirm all Firsty details directly in its app.

Frequently Asked Questions About Firsty eSIM
Is Firsty eSIM really free?
Firsty Free does not require the purchase of a data package. Eligible users watch an advertisement to unlock 30 minutes of basic mobile data at 256 Kbps, and additional advertisements provide more access time.
The exchange is attention rather than money. That makes it genuinely free in price, but it is not unrestricted high-speed service.
Does Firsty work for Canadian travellers?
Firsty’s current Free page includes North America among its eligible user regions, and Canada appears in its supported destination directory. Canadians can therefore install and use Firsty on an eligible, unlocked eSIM-compatible phone.
Travellers should still verify their exact device and destination before relying on it.
How fast is Firsty Free?
The current Firsty Free plan page lists a speed of 256 Kbps. That is intended for messaging, email, directions, and other essential tasks rather than smooth streaming or large downloads.
The connection may feel especially slow on image-heavy websites or apps that automatically load video.
Does Firsty eSIM support hotspot use?
Firsty promotes hotspot use on Classic and Unlimited. Classic hotspot activity uses the purchased bundle, while Unlimited activity counts toward the 5 GB daily full-speed amount.
The Free tier is not a practical hotspot plan because of its 256 Kbps speed.
Does Firsty provide calls and text messages?
Firsty is best treated as a data eSIM, but the app offers optional international calling credits. Users can see the destination rate before calling and use their own number as caller identification.
Regular incoming SMS, Canadian voicemail, and conventional number-based service should remain on your Canadian line.
Can I keep my Canadian number active while using Firsty?
A dual-SIM phone can keep the Canadian line enabled for calls and texts while using Firsty for mobile data. Firsty’s setup guidance recommends selecting the primary line for calls, texts, iMessage, and FaceTime, then selecting Firsty for data.
Turn off automatic mobile-data switching so the phone does not unexpectedly move data back to the Canadian line.
When does a Firsty Classic plan expire?
A Classic bundle provides 30 days of use after activation. Buying the package in advance does not start that period immediately, according to Firsty’s current Classic page.
This gives travellers the option to purchase before leaving Canada and activate when the trip begins.
What happens after I use 5 GB on Firsty Unlimited?
Unlimited continues working after the 5 GB daily full-speed amount is consumed, but speed drops to 512 Kbps. Full network speed returns automatically when the next 24-hour cycle begins.
A traveller who repeatedly reaches the threshold should check for laptop backups, video streaming, cloud uploads, app updates, or other background data use.
Is Firsty eSIM legitimate?
Firsty operates current iPhone and Android apps and publishes active plan, installation, coverage, and support documentation. Its app is available through Apple’s Canadian App Store and Google Play.
That establishes Firsty as an operating eSIM service, but it does not guarantee identical network performance in every destination. Coverage and speed still depend on local partner networks and conditions.

Final Thoughts
Firsty’s free data tier is worth having, but it needs to be judged for what it is designed to do. It provides a slow, basic connection for essential travel tasks when the alternative may be no connection at all.
For a Canadian traveller who mainly needs maps, messaging, email, or an airport ride, Firsty Free can be genuinely useful. I would install it as a backup even when another provider is handling the main travel data.
Classic is the better Firsty option for most ordinary vacations because it provides a fixed high-speed allowance, hotspot support, and 30 days of validity after activation. Unlimited is better for heavier users who understand that the plan includes 5 GB of full-speed data per day before slowing to 512 Kbps.
The final decision should be based on how disruptive a slow or unavailable connection would be. Free is appropriate when data is helpful. A paid plan is the safer choice when data is essential.
