eSIM Troubleshooting Guide: How to Fix Common eSIM Issues
If your eSIM is not working, check your coverage, selected data line and order instructions first. Keep the eSIM installed while you check. Deleting it may prevent you from reinstalling it, and you may not need to buy another plan.
Need help with an existing AloOui order? Send your order reference, exact device model, current destination and error message privately through the Help Center. Support can check the recovery options for your order.
Get help with your eSIM →Five Checks Before You Start
- Your device: confirm your exact model and regional version support downloadable eSIMs and that the phone is carrier-unlocked.
- Your destination: check that your purchased plan includes your current country.
- Your plan: check remaining data and validity where available. Usage information can take time to update.
- Your data line: confirm the intended eSIM is installed, enabled and selected for mobile data.
- Your settings: follow the roaming and APN instructions supplied for that eSIM. Do not apply the same settings to every line.
Find the Steps for Your Problem
1. Installation Failed or the eSIM Does Not Appear
Use a stable internet connection and check whether the eSIM is already listed in your SIM settings. Follow the installation method supplied with your order and the instructions for your device. If manual entry is offered, enter the supplied details exactly.
If the code is invalid or already used, send the exact message to support. Keep any installed eSIM in place while support checks whether recovery or a replacement code is available.
2. No Mobile Data, SOS Only or No Service
- Check that your current destination is included and the plan has not expired.
- Confirm the intended eSIM is enabled and selected for mobile data, and airplane mode is off.
- Follow your order's roaming and APN instructions for the travel line. Check your home line separately to avoid unintended carrier charges.
- Once installation has finished, briefly toggle airplane mode or restart the phone to refresh its connection. Do not interrupt an active eSIM download.
- Select a network manually only if your order or support names a supported partner. A network appearing in the phone's list does not mean your plan can use it.
An installed eSIM still needs supported destination coverage to connect. AloOui travel-eSIM validity begins when it connects to a supported destination network, not simply when you install it.
3. An Error Code Appears
Save the exact code, full message and the step where it appeared. The same number can mean different things on different phones or services, so send those details to support rather than guessing. Keep the eSIM installed and avoid resetting the phone based on a code alone.
4. Data Works but Is Slow
Check remaining high-speed data, any reduced-speed conditions, local signal and the apps using your allowance. Busy networks can also affect performance. Changing the phone's 4G or 5G setting may not solve the problem; follow the supported-network advice for your plan.
Did the Problem Start After a Border Crossing?
Check that your next country is included, then use the border-crossing troubleshooting guide for reconnection steps. It explains how to check the data line, settings and supported local network after moving between countries.
Before Resetting or Deleting Anything
Ask support before deleting the eSIM or factory-resetting your phone. Your installation code may not be reusable. A network reset can also change saved Wi-Fi and other settings, so check the device manufacturer's instructions first.
Keep your order reference and installation details private and accessible from another trusted device. A saved QR code alone does not guarantee you can reinstall or transfer the eSIM.
When to Contact Support
Contact the AloOui Help Center if the code is invalid, installation remains incomplete or data still does not work after these checks. Share your order reference, device model and software version, current destination, exact error and the steps you have tried. Hide QR codes and activation details in public screenshots.

Frequently Asked Questions
Should I delete an eSIM that is not working?
Keep it installed while you troubleshoot. Ask support to confirm recovery and reinstallation options before deleting it.
Does installing before departure start validity?
AloOui travel-eSIM validity begins when it connects to a supported destination network, not simply when you install it.
Does travel data cancel home-carrier charges?
No. Check each line's settings and your home carrier's call, SMS and roaming terms separately.
Will a new plan fix my phone?
Not necessarily. It cannot unlock a device or fix a hardware, software or account restriction. Check the existing issue before buying again.
