FAQ
If a family of four all switch, do we earn four offers?
If each member does an MNP in their own name, four offers can in principle count. But offers stating "one per household" are excluded.
Do I need a separate SIM-free handset?
An eSIM-capable handset works as-is. For a physical SIM, the new carrier mails you one.
