Choose it for mobile data
The eSIM can be active but unused when another SIM is still selected for data.
Follow the roaming and APN instructions
Many travel eSIMs need data roaming turned on. Some also require a specific APN.
Reconnect the phone
Turn airplane mode on and off, restart the phone and try the recommended network selection. Contact support with screenshots if it still does not work.
Follow the plan instructions
Phone menus and activation rules differ. Use the instructions that came with the exact plan you bought.
Common questions
What to check before you buy
Can I do these steps before departure?
You can complete many checks and installation steps over reliable Wi-Fi before travelling. First confirm what starts the plan so you do not begin it too early.
Do all phones use the same menu names?
No. Menu names differ by operating system, phone maker and software version. Use the phone maker’s current instructions when the wording is different.
What should I save offline?
Save the QR code or manual setup details, order number, provider instructions and support contact somewhere you can open without mobile data.
