An eSIM connected but no internet can be confusing because everything appears to be working. The eSIM is installed, your phone may show LTE, 4G or 5G, and you might even have several signal bars, but websites, maps and apps still refuse to load.
The important thing to understand is that having signal does not automatically mean mobile data is working through the eSIM. Your phone can register on a mobile network while the wrong SIM is selected for data, roaming is configured incorrectly, the plan has run out of data, or the provider has not established a usable data connection.
This guide is specifically for that situation: the eSIM is installed and appears connected, but mobile internet does not work. If your eSIM will not activate, shows No Service or SOS, or your phone is missing the Add eSIM option, those are different problems with different troubleshooting paths.
eSIM Has Signal but No Internet? Start Here
When an eSIM has signal but no data, what you see on the phone can help narrow down where the problem is.
| What you see | What to check first |
|---|---|
| Signal bars but websites and apps do not load | Confirm the eSIM is selected for mobile data |
| Travel eSIM has signal after arriving abroad | Check whether roaming is required on the travel eSIM |
| Data worked earlier and suddenly stopped | Check remaining data and plan validity |
| Data stopped after moving to another country or network | Refresh the network connection and check supported networks |
| Correct eSIM and active plan but still no data | Check the provider’s APN instructions |
| No Service or SOS instead of signal bars | Treat it as a network-registration problem rather than a no-data problem |
If you have No Service, SOS or no signal at all, start with the broader eSIM Troubleshooting guide instead. The new troubleshooting pillar separates network-registration failures from mobile-data-routing problems so you can follow the right branch without changing unrelated settings.
Why Can an eSIM Have Signal but No Internet?
Signal bars mainly tell you that the phone can see and register with a mobile network. They do not prove that the phone is successfully sending internet traffic through the eSIM.
Several separate pieces still need to work. The eSIM profile must be enabled, mobile data must be turned on, the correct SIM needs to be selected for data, the plan needs to be active, and the phone needs the right network configuration.
This is especially easy to overlook on a Dual SIM phone. Your travel eSIM can show full signal while your iPhone or Android phone is still trying to use your Canadian SIM for mobile data.
That is why changing random settings is rarely the best first move. Work through the connection in order.
1. Confirm the Problem Is Mobile Data
Turn Wi-Fi off temporarily before troubleshooting.
Then open a normal website or another app that normally uses the internet. If one particular app is not working but everything else loads normally, the eSIM connection may not be the problem.
Also look at the status bar. You may see LTE, 4G or 5G beside the signal indicator, although the exact display depends on your phone and carrier.
If nothing loads once Wi-Fi is disabled, continue with the mobile-data checks below.
2. Check That Mobile Data Is Turned On
An eSIM can remain installed and connected to a network even when mobile data has been disabled.
On an iPhone, go to Settings > Cellular and make sure Cellular Data is turned on.
On a Google Pixel, Google currently places these controls under Settings > Network & internet > SIMs. Make sure Mobile data is enabled for the line you want to use. Google’s Pixel mobile-network guidance also shows the roaming, network and APN controls available in the same area.
On Samsung Galaxy phones, mobile-data and SIM controls are normally found under Settings > Connections, although the exact wording can vary by model, Android version and carrier.
If mobile data was already on, the next check is particularly important when you have two SIMs.
3. Make Sure the Correct eSIM Is Selected for Mobile Data
This is one of the first things I would check when an eSIM has signal but no data.
A Dual SIM phone can keep two lines active while using only one of them as the main cellular-data connection. If your Canadian SIM remains selected for data, your travel eSIM can look perfectly connected without actually carrying your internet traffic.
| Phone | Where to check the data SIM |
|---|---|
| iPhone | Settings > Cellular > Cellular Data |
| Samsung Galaxy | Settings > Connections > SIM manager |
| Google Pixel | Settings > Network & internet > SIMs |
Apple’s current Dual SIM guidance allows separate voice and data plans, which is useful when keeping a Canadian number active while using another eSIM for data.
Google also notes that only one SIM can be the default for mobile data at a time.
If the correct line is selected but data still does not work, continue with the eSIM line and roaming checks.
4. Confirm the eSIM Line Is Turned On
Selecting the correct data line will not help if the eSIM itself has been disabled.
This can happen after switching plans, changing SIM settings or experimenting with Dual SIM options.
Check the eSIM in your phone’s SIM settings and make sure the line is enabled.
On a Pixel, for example, Google specifically recommends checking that Use SIM is turned on when troubleshooting mobile-data problems.
If the eSIM is enabled and selected for data but the internet still does not work, check roaming next if you are travelling.
5. Check Data Roaming on a Travel eSIM
Many international travel eSIMs connect through partner networks and require Data Roaming to be enabled on the travel line.
But this is not a universal eSIM rule.
Follow the instructions supplied by the travel eSIM provider. If the provider tells you that roaming is required, turn it on for the travel eSIM, not automatically for every SIM in the phone.
On an iPhone with Dual SIM, Apple lets you change roaming separately for each line under the Cellular settings. Apple’s data-roaming guidance also recommends following the settings provided by your carrier.
Using a Travel eSIM With a Canadian SIM
For many Canadians travelling abroad, a practical Dual SIM setup looks like this:
- Travel eSIM: selected for mobile data
- Travel eSIM roaming: on when required by the travel provider
- Canadian SIM: available for calls or texts if you need it
- Canadian SIM data roaming: off unless you intentionally want to use your Canadian carrier’s roaming service
Be careful with automatic cellular-data switching or fallback features. You do not want your phone quietly moving data back to your Canadian line and triggering roaming charges.
For a broader explanation of the trade-offs, see Travel eSIM vs International Roaming for Canadians.
6. Refresh the Mobile Network Connection
If the basic settings are correct, the phone may simply need to register with the network again.
Turn Airplane Mode on briefly, then turn it off and give the phone a moment to reconnect.
If that does not help, restart the phone.
These steps are particularly useful after:
- landing in another country
- moving between coverage areas
- changing mobile networks
- switching the active data SIM
- activating a travel eSIM
- crossing a border
Google includes connection refreshes and restart-related checks in its current Pixel mobile connectivity troubleshooting.
If your signal returns but mobile data still does not work, the next step is to check the plan itself.
7. Verify Your eSIM Plan Is Still Active
Do not assume the phone is the problem.
Open the carrier or travel eSIM provider’s app, website or account dashboard and check the plan status.
Look for:
- whether the plan has activated
- how much data remains
- the plan’s expiry or validity date
- whether the current country is included
- whether a top-up is required
- whether the provider shows any account or service warning
An eSIM can continue to appear in your phone after its data package has expired or been used up.
Some travel plans also activate according to specific rules, such as first network connection or a defined activation date. If the eSIM has never provided working data, check the provider’s activation instructions rather than assuming the installation itself failed.
If the profile never activated properly in the first place, see What to Do If eSIM Activation Fails in Canada.
8. Review the Selected Mobile Network
Automatic network selection is usually the safest setting because it lets your phone choose an available supported network.
If automatic selection is not working, some travel eSIM providers recommend manually selecting one of their supported partner networks.
Do not choose a random carrier simply because it appears in the network list. A travel eSIM may only be authorized to use certain networks in that country.
Check the provider’s instructions first.
This can be particularly useful when the eSIM worked in one location and stopped after:
- entering another country
- leaving an airport
- moving between regions
- losing coverage for an extended period
- reconnecting after a flight
If the eSIM has No Service rather than signal with no internet, return to the main eSIM troubleshooting guide because the problem is occurring earlier in the connection process.
9. Troubleshoot the APN If the Simpler Fixes Did Not Work
The Access Point Name, or APN, helps the phone establish the correct mobile-data connection with the network.
A missing or incorrect APN can therefore produce one of the most confusing eSIM problems: the phone registers on the network and shows signal, but mobile internet still does not work.
Do not start changing APN fields from random websites.
Use only the APN supplied by your mobile carrier or eSIM provider.
On a Google Pixel, APN settings can be found under the SIM’s mobile-network settings. Google describes Access Point Names as part of the information used by the carrier to connect the phone securely.
On many Samsung Galaxy phones, the path is generally:
Settings > Connections > Mobile networks > Access Point Names
Samsung’s APN guidance also recommends obtaining the correct settings from the network provider.
If your provider automatically configures the APN and its instructions do not tell you to edit anything, leave it alone.
APN troubleshooting is a distinct problem of its own, so avoid turning this into a full manual APN setup unless the provider specifically directs you to change those values.
10. Know When the Problem Is the Plan, Not the Phone
By this point, you can usually separate a phone-settings problem from a provider or plan problem.
| More likely a phone/settings problem | More likely a plan/provider problem |
|---|---|
| Wrong SIM was selected for data | Data allowance is exhausted |
| Mobile data was turned off | Plan validity has ended |
| Travel-line roaming was configured incorrectly | Current destination is not covered |
| Airplane Mode restores the connection | Provider account shows inactive or suspended |
| Correcting the APN restores data | Provider reports an outage |
| Manual supported-network selection works | Provisioning needs to be refreshed by the provider |
This distinction can save a lot of unnecessary troubleshooting.
If every relevant phone setting matches the provider’s instructions and the plan should still be valid, stop changing settings and contact the provider.
They may need to confirm provisioning, network authorization or account status from their side.
11. Reset Mobile Network Settings Only After the Easier Checks
A mobile-network reset is more disruptive than changing the selected data SIM or toggling Airplane Mode, so it should not be the first fix.
On current Google Pixel phones, Google provides:
Settings > System > Reset options > Reset Mobile Network Settings
Other Android phones use similar wording, but the exact path varies.
On iPhone, reset options are under:
Settings > General > Transfer or Reset iPhone > Reset
A network reset can remove saved Wi-Fi, VPN, preferred-network and APN settings, depending on the phone. Use it only after the simpler checks above and read the reset description on your device before confirming.
I would only reach this step after checking the data line, roaming requirement, plan status, network selection and APN.
Do Not Delete the eSIM as Your First Fix
Deleting an eSIM can make the problem harder to solve.
Some carrier or travel eSIM profiles cannot simply be installed again with the same QR code. You may need new activation details, carrier assistance or a replacement profile.
If the eSIM is already installed and showing signal, that is another reason not to remove it while you are still diagnosing a mobile-data problem.
This also keeps the troubleshooting sequence separate from a genuine reinstallation problem. If you have already deleted the profile or confirmed that reinstallation is required, follow How to Reinstall or Reactivate an eSIM in Canada instead.
eSIM Mobile Data Not Working on iPhone
For an iPhone that shows signal but has no internet, check these settings in this order:
- Turn Wi-Fi off temporarily.
- Open Settings > Cellular and confirm Cellular Data is on.
- If you have more than one SIM, open Cellular Data and select the correct eSIM.
- Tap the eSIM and make sure the line is turned on.
- If it is a travel eSIM, follow the provider’s roaming instructions for that line.
- Toggle Airplane Mode and reconnect.
- Check the provider’s plan status and remaining data.
- Check network or APN instructions only if the earlier steps do not solve the problem.
If the iPhone shows SOS or No Service instead of usable signal, move to network-registration troubleshooting rather than continuing through mobile-data fixes.
eSIM Mobile Data Not Working on Samsung Galaxy
On a Samsung Galaxy phone, start with:
Settings > Connections > SIM manager
Confirm the eSIM is enabled and selected for mobile data.
Then check Settings > Connections > Mobile networks for the relevant data-roaming or network options.
If you need to inspect the APN, look under Access Point Names and compare the settings only with information supplied by the carrier or eSIM provider.
Samsung menus can differ between models, carriers and One UI versions, so use the closest matching option rather than changing unrelated settings.
eSIM Mobile Data Not Working on Google Pixel
Go to:
Settings > Network & internet > SIMs
Check:
- Use SIM is on
- Mobile data is on
- the eSIM is selected as the data SIM
- Roaming matches the provider’s instructions
- the selected network is appropriate
- the APN matches provider instructions if a manual APN is required
Google also provides a Reset Mobile Network Settings option under System settings if the normal checks fail.
What If Your Phone Supports eSIM but the Connection Still Does Not Work?
If you are repeatedly having trouble even though the settings above look correct, make sure the issue is not actually device or carrier compatibility.
The phone may support eSIM hardware generally while still having a problem with its exact regional model, carrier lock, firmware, EID, Canadian network support or carrier provisioning.
That is a different troubleshooting path from a normal signal-with-no-data problem. See Phone Supports eSIM But Not Working in Canada? Here’s What to Check if compatibility itself is in doubt.
When to Contact Your Carrier or eSIM Provider
Contact the provider once the phone appears correctly configured but mobile data still will not establish a connection.
Before contacting support, gather:
- phone make and model
- destination or current country
- name of the eSIM plan
- whether signal bars appear
- whether LTE, 4G or 5G appears
- whether mobile data is enabled
- whether the eSIM is selected as the data line
- whether roaming is enabled when required
- the network currently selected
- whether the plan still shows available data
That gives support something useful to investigate rather than forcing you to repeat the same basic checks.
For a Canadian carrier eSIM with broader activation, compatibility or service problems, How to Fix eSIM Not Working in Canada covers the wider troubleshooting path.
eSIM Connected but No Internet FAQs
Why does my eSIM show bars but no internet?
Signal bars mean your phone has registered on a mobile network, but they do not confirm that mobile data is actually working through the eSIM. The wrong SIM may be selected for data, mobile data may be off, a travel eSIM may need roaming enabled, or the plan may no longer have usable data.
Start by turning Wi-Fi off and confirming that the eSIM is enabled and selected for mobile data. If those settings are correct, check the plan’s remaining data and validity, then move on to network selection and the provider’s APN instructions. On Dual SIM phones, pay particular attention to which line is carrying data because only one line normally handles the primary mobile-data connection.
Do I need to turn on data roaming for a travel eSIM?
Many travel eSIMs require data roaming because they connect through partner networks in the country you are visiting, but not every travel eSIM works the same way. Follow the setup instructions for the specific provider and plan rather than enabling roaming simply because the line is an eSIM. Saily, for example, currently instructs customers to enable roaming on its travel eSIM.
If you are using a travel eSIM alongside a Canadian SIM, make sure you are changing the setting on the correct line. The travel eSIM may need roaming enabled while roaming remains off on your Canadian line unless you intentionally want to use your Canadian carrier abroad.
Does resetting network settings delete an installed eSIM?
A normal Reset Network Settings action on an iPhone is separate from Apple’s Delete All eSIMs option. Apple documents them as different reset actions, so resetting network settings is not the same thing as choosing to erase your installed eSIM profiles. The network reset can remove previously used networks and certain VPN and cellular settings, so you may need to reconnect or recheck some settings afterwards.
Android devices should be treated more carefully because reset menus vary by manufacturer and software version. On Pixel, Google documents Reset Mobile Network Settings separately from the Erase eSIM command, but you should still read the confirmation screen before proceeding and avoid any option that specifically says it will erase or delete a SIM or eSIM.
What causes an eSIM to suddenly stop working?
If the eSIM was working normally and then lost mobile data, check the things that can change without reinstalling the profile. The data allowance may be exhausted, the plan may have expired, the phone may have switched to another SIM for data, or the device may need to register again after changing networks or locations.
Travel can add another possibility. After entering a new country or reconnecting to a different partner network, the plan must still cover that destination and the phone may need the correct roaming or network settings. If Airplane Mode or a restart restores data, that points more toward a temporary network-registration problem than a damaged eSIM profile.
How do I fix incorrect APN settings on an eSIM?
Use the APN supplied by your carrier or eSIM provider rather than copying settings from another network or an unofficial website. An incorrect APN can stop cellular data from working even when the phone has signal.
On iPhone, Apple allows APN viewing or editing only when the carrier permits it. The setting may appear under Settings > Cellular > Cellular Data Network, and Apple provides a Reset Settings option to restore the carrier’s default APN information when available. On Samsung Galaxy phones, APNs are generally under Settings > Connections > Mobile networks > Access Point Names. On Pixel, APN controls are under Settings > Network & internet > SIMs. If the provider normally configures the APN automatically, do not manually replace it unless its support instructions tell you to.
Should I delete and reinstall a broken eSIM profile?
Deletion should be a later troubleshooting step, not the first response to an eSIM that still shows signal. If the real problem is the selected data line, roaming, APN, plan status or network registration, deleting the profile will not address the cause and can create a new activation problem.
Apple specifically advises against erasing an eSIM for troubleshooting unless your carrier tells you to do so. If an iPhone eSIM is erased, Apple says you will need to contact the carrier to obtain a new one and set it up again. Other carriers and travel eSIM providers have their own reinstallation rules, so do not assume an old QR code or activation detail can always be reused. Confirm the provider’s reinstallation process before deleting a profile that is already installed.

Final Thoughts
An eSIM that has signal but no internet usually does not need to be deleted or completely set up again.
Start by confirming that mobile data is on and that the correct eSIM is actually carrying it. For a travel eSIM, check the provider’s roaming requirement. Then move through plan status, network registration, supported networks and APN settings in that order.
The key is to troubleshoot the data connection separately from the eSIM installation. Once the phone is already recognizing the eSIM and registering on a network, the problem is usually further down the connection path.
