Frequently asked questions
Can I keep my number if I move to Sky Mobile?
Yes. Text PAC to 65075 from your current phone to get a free switching code, then give it to Sky Mobile. Your number normally moves within one working day.
Is Sky Mobile coverage the same as O2?
It uses O2's masts, so outdoor coverage is broadly the same. Some features, such as 5G or Wi-Fi calling, can differ — check Sky Mobile's site.
Will Sky 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.
