Travel eSIM Not Working? Fix the Most Common Problems

A safe troubleshooting order for installation errors, no service, no data, roaming settings, network selection and APN issues.

Quick answer First confirm you are inside the plan's coverage and validity window. Then verify the eSIM line is enabled, selected for mobile data and configured according to the provider's roaming instructions. Toggle Airplane Mode, restart and try automatic network selection before deleting anything. Do this in order Do not delete the eSIM profile; it may not be reusable. Confirm destination, start date, remaining data and device unlocking. Enable the travel line and select it for cellular data. Check the plan's roaming and APN instructions. Restart, then test automatic and approved manual networks. Installed but no service A travel plan may show no service outside its destination. After arrival, make sure the line is on and automatic network selection is enabled. Toggle Airplane Mode for about 15 seconds or restart so the phone performs a fresh network registration.

A QR code may be single-use or already installed. Look for the profile in SIM settings before scanning again, and contact support with the order and device details if the code is rejected. Troubleshooting FAQs Should I delete and reinstall the eSIM? Not unless support tells you to. Some profiles can be installed only once, so deletion can make recovery harder. Why must roaming be on for a travel eSIM? Many travel eSIMs connect through partner networks, so the travel line may require roaming. Keep home-line roaming configured separately. Why does one network work but another does not? The plan may support only specific partner networks. Use automatic selection first, then only approved networks listed by the provider. What should I send support? Send the order ID, destination, phone model, current location, screenshots of SIM and network settings, and the exact error. Do not publish QR codes or activation credentials.
