eSIM Troubleshooting
Find the right checks for activation errors, No Service, missing mobile data, slow connections and hotspot problems. Start with the basics below, then choose your symptom for clear next steps.
Start Here
3 questionsStart with the plan and the selected data line. Work through these checks before changing advanced settings:
- Confirm that your package covers your current country, is active and has usable data remaining.
- Check that the travel eSIM is installed, enabled and selected for mobile data.
- Apply the provider’s data-roaming and APN instructions for that package.
- Turn airplane mode on briefly, then turn it off to refresh the connection.
- Turn Wi-Fi off briefly and try loading a new webpage.
If needed, restart the phone. Then follow the checks for No Service or signal without data. Keep the eSIM installed while troubleshooting; deleting it can make recovery harder.
No Service usually means the line has not registered on a usable mobile network. Confirm that the travel line is enabled and that your package covers the country you are in. Before arrival, a destination-only eSIM may have no service.
Move somewhere with better reception, restart the connection and allow the phone to register. Start with automatic network selection; if it fails, try an operator specifically listed for your package. A network appearing in the scan does not mean your plan can use it. Follow the network-selection checks.
Signal bars do not guarantee that the selected line has a working internet connection. On a Dual SIM phone, first check that the bars belong to the travel eSIM.
- Select that eSIM for mobile data and make sure mobile data is on.
- Check its roaming setting against the provider’s instructions.
- Confirm the package is active, unexpired and has data remaining.
- Check the APN if the provider requires a manual value.
Test a new webpage with Wi-Fi off. If only one app fails, use the app-specific checks. Our full eSIM troubleshooting guide explains the broader process.
Installation and Activation
5 questionsIf the profile already appears in your phone’s SIM settings, a travel eSIM can remain on Activating before you reach its supported destination. That status alone does not prove the installation failed.
Airalo documents this behavior on iOS. Check your own package’s activation policy rather than repeatedly reinstalling it. If you are already in coverage, confirm the required settings, restart and contact support if activation still fails. The phone’s status label is not a reliable substitute for the provider’s package-validity information.
An activation error can come from an unsupported device, carrier lock, used or expired installation code, incorrect manual details or a provider-side provisioning problem.
Keep the exact error message, use a stable internet connection and check whether the profile has already appeared in your SIM list. Confirm your exact model is compatible and can use the provider’s service. Apple’s eSIM setup troubleshooting covers iPhone checks. If the error continues, send the details to the provider before deleting the profile or buying a replacement.
First check whether the eSIM is already installed. If it is not, connect to stable Wi-Fi and display the complete QR code clearly on another screen or printout. Avoid cropping, glare and excessive zoom.
If scanning still fails, use the provider’s direct-install option or manual details when available. Manual entry will not make an expired or already-used code valid again. Ask the provider to check the code’s status. See the installation and activation FAQ for the available methods.
The profile may already be installed on this phone, attached to another device or recorded as used after an earlier installation attempt.
Check every line in the phone’s SIM list, including unfamiliar labels. Compare its identifier with the provider’s record if available. If you find the correct profile, follow the connection instructions instead of scanning again. Otherwise, ask whether transfer, recovery or reissue is supported. Do not delete an existing profile just to retry the code.
Check the exact model and regional version, not just the phone’s product name. Some versions lack eSIM support, and menu names vary by manufacturer and software.
Search Settings for eSIM or SIM manager, check the manufacturer’s instructions and install a supported software update if needed. A managed work device may also restrict cellular-plan changes. A carrier lock can block using another provider, but a missing menu alone does not prove the phone is locked. Start with our eSIM compatibility guide.
Roaming, APN and Networks
6 questionsAfter landing, check the travel line’s setup in this order:
- Turn airplane mode off.
- Enable the travel eSIM and select it for mobile data.
- Set data roaming and any required APN according to the provider.
- Confirm that the package includes your destination and has started.
- Allow time to register, then try a supported network manually if automatic selection fails.
Airport buildings can have weak indoor reception. Try another location before assuming the plan is faulty. The travel and roaming FAQ explains arrival settings.
Often yes, when the travel provider requires it. Many travel eSIMs use roaming agreements to access local networks. Follow the instructions for the exact package.
Make sure you are changing the travel line’s setting. Keep home-line data roaming off unless you intend to use its roaming service, and review automatic data switching. Android controls vary, so check which SIM a setting applies to. Enabling roaming does not add countries to your package or make home-line calls and texts free.
The Access Point Name, or APN, must match the provider’s connection instructions when manual configuration is required.
- iPhone: look under Cellular or Mobile Data for the selected line’s Cellular Data Network or Mobile Data Network menu, if available.
- Android: open the selected SIM’s mobile network settings and look for Access Point Names.
Enter the supplied value without extra spaces; change other fields only if instructed. On Android, save and select the APN when required. Apple’s APN guide explains carrier-controlled settings.
A missing APN menu does not automatically indicate a fault. Some carriers configure it automatically or prevent manual editing. On iPhone, the carrier determines whether you can view or change the APN.
If the connection fails, confirm that you are viewing the correct SIM and ask the provider whether this package needs a manual APN. Check for supported carrier or software updates. Do not install an unrelated configuration profile to reveal the field. On a managed device, ask the administrator if cellular settings are restricted.
A network name that differs from the eSIM seller’s brand can be normal: travel packages use local partner operators. Check the network list for your exact package and destination.
If the selected operator is unsupported or performing poorly, turn off automatic selection and try a listed alternative. If none registers, return to automatic and contact support. Restore automatic selection when changing countries unless the provider says otherwise. The coverage and networks FAQ explains how partner access works.
Check for automatic data switching, backup-data or data-during-calls features. Their behavior depends on the phone, carrier and roaming situation; switching is not available in every configuration.
Select the travel eSIM as the default data line and disable optional switching if you want to control data use. Recheck the selection after a restart or SIM change. With switching disabled, mobile data may stop during a call on the other line. See the Dual SIM FAQ for the trade-offs.
Top-Ups and Connection Stability
5 questionsCheck that payment completed and the top-up was attached to the intended eSIM. Compare the package’s destination and activation status with the profile selected for mobile data.
A queued top-up may wait until the previous package expires or its data runs out. If it should already be active, follow the provider’s connection instructions, refresh the app and restart the connection. Do not buy a second top-up solely because the balance display has not updated. Contact support with the receipt if necessary; the plans and validity FAQ explains top-up timing.
Check the selected data line, roaming setting and any manually entered APN. An update can affect these preferences; on iPhone, an iOS update can reset a manually changed APN to its default.
Restart the device and restore only the settings specified by your provider. On iPhone, check Settings > General > About for an available carrier-settings update. If the issue remains, record the OS version and when service stopped so support can investigate. Keep the installed profile while they check.
Give the phone time to reconnect, then check that the travel eSIM is enabled and still selected for mobile data. Confirm that airplane mode is off and that the package remains valid.
If the phone requests a SIM PIN, enter it only if you know it; ask the carrier if unsure. An old manual-network choice may also prevent registration after changing countries. Return to automatic selection or choose a supported operator. Use the connection-restart steps if it still does not connect.
Common causes include weak reception, congestion, a used-up high-speed allowance, background traffic or a long route to the service you are using.
- Check the package’s remaining high-speed data and fair-use policy.
- Pause downloads, backups and hotspot traffic.
- Move to a location with better reception.
- Try another supported operator if your package allows it.
If a VPN is optional, compare a brief test with it on and off. Avoid repeated speed tests on a small allowance because they consume data. See the speed and coverage FAQ.
Notice when the connection drops: while moving, in one building, during calls or even when stationary. This helps distinguish coverage problems from settings or device issues.
Restart the phone, try a listed partner network and check for supported updates over Wi-Fi. If 5G is unstable, temporarily try LTE/4G where your phone and plan allow it. If drops occur only during calls on the other SIM, check Dual SIM behavior. Record the locations, times and network names for support instead of repeatedly reinstalling the eSIM.
Hotspot, Calls and Apps
6 questionsFirst check that mobile data works on the phone itself with Wi-Fi off. If it does not, fix that connection before troubleshooting the hotspot.
If phone data works, confirm that the package permits tethering and has hotspot allowance remaining. Enable Personal Hotspot or Mobile Hotspot, check the network name and password, then restart both devices. Use a separate hotspot APN only if the provider supplies one. The hotspot troubleshooting steps cover the setup in more detail.
First identify which number should receive the call. A data-only travel eSIM does not provide ordinary cellular voice service of its own.
For your home number, make sure that line is enabled and has service at your destination or a supported Wi-Fi Calling connection. Check call filtering and forwarding if the line is connected but calls still fail. On some Dual SIM setups, the other number becomes unavailable during an active call. Your home carrier’s calling and roaming terms still apply.
Verification texts normally go to the number registered with the account. Check that its SIM is enabled and can receive SMS abroad; selecting the travel eSIM for data does not move those messages to it.
Try receiving an ordinary SMS. If that works but the code does not, check the registered number, blocked-message filters and the sender’s verification options. Ordinary SMS reception does not require home-line mobile data roaming. Use an existing authenticator or backup method if available, and contact the sender or home carrier if delivery still fails.
Your eSIM may connect to a local mobile network while routing internet traffic through a gateway abroad. Websites can therefore associate the public IP address with another country.
A VPN, virtual-location feature or inaccurate IP-location database can also affect the result. This is different from your phone’s GPS location and does not by itself prove the eSIM is misconfigured. If a service is affected, check the provider’s expected routing and use the app-specific troubleshooting steps.
If other apps and websites work, check the affected app before changing the eSIM setup:
- Make sure the app is allowed to use mobile data.
- Check any data-saving or background-data restrictions.
- Restart or update the app and check its service status.
- Compare with Wi-Fi and, if optional, briefly test without a VPN or content filter.
Some services also apply account, regional or IP-based restrictions. Follow the app provider’s guidance if it reports one. Changing the local mobile operator does not necessarily change the eSIM’s public IP location.
First establish whether ordinary mobile internet works. If the VPN is optional, disconnect it briefly and try a non-sensitive webpage. If that fails too, troubleshoot the underlying eSIM connection.
If only the VPN fails, try another server, a supported alternative protocol or the VPN app’s automatic protocol setting. Check for app updates and account or service issues. Proton VPN’s connection guide explains these checks. Restore the VPN after testing; for a managed work VPN, ask your IT team before changing its configuration.
Resets and Support
5 questionsIt can help after simpler checks fail, but first save your Wi-Fi password and the provider’s required connection settings.
On iPhone, use Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This resets saved Wi-Fi connections and network preferences, including relevant VPN and APN settings; roaming may need to be enabled again.
Android reset options and their scope vary. Read the confirmation carefully and avoid any option to erase downloaded SIMs or factory-reset the phone. Apple’s reset guide also distinguishes Reset Network Settings from Delete All eSIMs.
Only after the provider confirms how you can recover or replace it. Some installation codes cannot be reused, and a deleted profile may need to be reissued.
Try checking the settings, restarting the connection and contacting support first. Apple advises against erasing an eSIM as a troubleshooting step unless the carrier directs you to. Turning a line off and back on is different from deleting it. Removing the profile also does not by itself cancel a subscription or refund the package.
You can refresh the connection without deleting the profile:
- Open the phone’s SIM settings and switch the affected line off.
- Wait about 30 seconds, then switch the line back on.
- Confirm that it is selected for mobile data and its roaming setting is correct.
- Allow it to register, then test a webpage with Wi-Fi off.
Alternatively, enable airplane mode briefly and then disable it. For iPhone, Apple recommends leaving it on for at least 15 seconds. Restart the phone if needed. These steps do not pause the package’s validity period.
Check the provider’s official status page if it has one, app notices and support updates. The local partner network may also publish an outage notice for your area.
Try another operator only if your package supports it. A working SIM on a different network does not rule out an outage on yours. Use Wi-Fi to contact support and ask them to check your package and location. Recent customer reports can provide clues, but do not confirm a network-wide incident.
Send a short, complete report through the provider’s official support channel:
- Your order reference and package name.
- The country, city or area, and when the issue started, including the time zone.
- The exact phone model and operating-system version.
- The error message and relevant screenshots.
- The selected data line, network, roaming setting and APN if applicable.
- The package’s remaining data and expiry status.
- What you have tried and whether the connection worked previously.
Share device or eSIM identifiers such as ICCID, EID or IMEI privately if support requests them. Keep QR codes and activation details out of public posts, and never send account passwords or one-time login codes.
