Frequently asked questions
Can I keep my number if I move to iD Mobile?
Yes. Text PAC to 65075 from your current phone to get a free switching code, then give it to iD Mobile. Your number normally moves within one working day.
Is iD Mobile coverage the same as Three?
It uses Three's masts, so outdoor coverage is broadly the same. Some features, such as 5G or Wi-Fi calling, can differ — check iD Mobile's site.
Will iD Mobile credit check me?
Pay-monthly plans usually involve a credit check; pay-as-you-go does not. CompareDirect is not a credit broker and does not run credit checks.
