Bills & switching · UK guide

Switch mobile network — keep your number, cut your bill.

Last verified 21 Jun 2026 · Source Ofcom + Citizens Advice

Switching mobile provider takes minutes and one text. To keep your number, text PAC to 65075; for a new number, text STAC to 75075. Want to check exit fees first? Text INFO to 85075. Your code lasts 30 days, you give it to the new network, and your old one can’t charge you for notice after the switch. Here’s the whole thing.

The three texts

Text thisTo this numberWhat you get
INFO85075Any early-exit charges, without committing to switch — check this first.
PAC65075Your PAC (to keep your number) + any exit charges. Reply within a minute; code lasts 30 days.
STAC75075Your STAC (to switch with a new number, closing the old account).

Then just sign up with the new provider and give them the code. With a PAC, your number transfers — usually within one working day — and the two providers coordinate so you don’t pay twice. It works the same on pay-monthly and SIM-only; pay-as-you-go can transfer credit/number too.

You don’t have to phone up and be talked out of it

This text-to-switch system exists so you never have to sit through a “retentions” call. You can request the code by text and hand it to the new network — no awkward cancellation conversation required.

When you can leave free

  • Out of contract / minimum term ended: switch with no exit fee — and you should, because staying often means paying for a handset you’ve already finished paying off.
  • Still in your minimum term: you may owe the remaining line rental as an early-exit charge (text INFO to 85075 to see it). Sometimes the savings on a cheaper deal still beat the exit fee — do the maths.
  • Mid-contract price rise above what you agreed: you may have a penalty-free exit — see our mid-contract price-rise guide.
  • No charging for notice after you switch: Ofcom bans your old provider from billing you for a notice period that runs after the switch date.

Cut the bill while you’re at it

  • Drop to SIM-only once your handset is paid off — often a fraction of the bundled price for the same network.
  • Compare on a price-comparison site before you pick the new deal; check coverage at your postcode.
  • On a low income or benefits? Some providers offer cheap social tariffs — see our social tariff guide (covers mobile and broadband).
  • Keep your handset and just move the SIM — you rarely need a new phone to switch.

Switching mobile — common questions

Will I lose my number or have a gap with no signal?

No. With a PAC your number moves to the new network, usually within one working day, and switching is designed to avoid a gap. You keep using your phone in the meantime.

Do I have to call to cancel?

No. The PAC/STAC text process means giving the code to your new provider closes the old account — no cancellation call needed.

What if I'm still in contract?

You can still switch, but you may pay an early-exit charge (the remaining line rental). Text INFO to 85075 to see the amount, then compare it against the savings on a cheaper deal.

My provider raised the price mid-contract — can I leave free?

Possibly. If the rise is more than you agreed to, you may have a penalty-free exit. See our broadband & mobile price-rise guide for the current rules.

One text could save you hundreds a year.
