A travel eSIM is quick to use once it is set up, and most problems come from a missed step. Work through this checklist and you will be online when you land.
A week before you fly
- Check that your phone supports eSIM and is unlocked: device compatibility.
- Choose a plan that covers your route, data and dates: How to choose a travel eSIM.
- Note where the QR code will arrive: your email and your account.
- If your bank sends security codes by SMS, decide how you will receive them abroad: Keep your number with a travel eSIM.
The day before
- Install the eSIM while you have Wi-Fi. The guides for iPhone and Android show each step.
- Label the new line, for example "Travel", and choose it for mobile data.
- If the plan starts at first connection, leave the eSIM line switched off until you land, so the days do not start early.
- Download offline maps and anything you want to stream.
When you land
- Switch on the travel eSIM line.
- Turn on data roaming for that line. Travel eSIMs need it.
- Wait a minute for the phone to find a network. If nothing happens, switch airplane mode on for ten seconds and off again.
- Turn off mobile data for your home SIM if you do not want roaming charges.
If something does not work
- Check that the eSIM line is on, selected for mobile data and has data roaming enabled.
- Restart the phone.
- Check that the network is not set to a fixed operator: choose automatic network selection, or pick another operator from the plan's list.
- Check the APN if your setup instructions ask you to enter one.
- Read the troubleshooting guides: connection issues, slow speeds and activation issues.
- Contact support with your order number and, if asked, the ICCID of the eSIM.
On the way home
- Switch mobile data back to your home SIM.
- Switch off the travel eSIM line. Do not delete it unless support tells you to: most QR codes can be installed once.
- If the plan can be topped up and you travel again, check your account before buying a new one.
