Check that the phone is unlocked
A phone can support eSIM and still be locked to one mobile network. It must be allowed to use another provider.
Check how many eSIMs your phone can store
Some phones can store several eSIMs but allow only a limited number to be active at the same time.
Check the destination separately
Phone compatibility does not guarantee that a plan covers your destination. Read the country and network details before buying.
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.
