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.
