How to Keep Your Phone Number When Switching Networks (UK)

Switching mobile networks in the UK is easier than ever — and you can keep your number with almost no hassle.

Whether you’re moving to a cheaper SIM-only deal or improving your coverage, the process is straightforward.

Can you keep your number when switching networks?

Yes — in the UK you can keep your number when moving between:

  • EE
  • O2
  • Vodafone
  • Three
  • and most smaller SIM providers (MVNOs)

The easiest way: Text to switch (PAC code)

The UK now has a simple system.

To get your PAC code, text:

PAC to 65075

This works on almost every UK network.

You’ll receive a message containing:

  • your PAC code
  • any exit fees (if relevant)
  • the date the PAC expires

How long does it take?

Usually:

1 working day after you give your new provider the PAC code

In many cases, your number will switch the next day.

What happens during the switch?

Most of the time:

  • your old SIM will stop working
  • your new SIM will activate with your number

You might have a short window where calls/texts don’t work, but it’s normally quick.

What if you don’t want to keep your number?

If you want a new number, you can just:

  • order a new SIM
  • activate it normally
  • and don’t request a PAC

Important tips

  • Make sure your phone is unlocked
  • If you’re on a contract, check exit fees
  • Save important numbers before switching (just in case)

The takeaway

Keeping your number in the UK is simple.

Text PAC to 65075, give the code to your new provider, and your number usually moves over within a day.
