SWITCHING GUIDE

Switch networks in one working day

PAC codes, STAC codes โ€” how to move to any UK network while keeping your number.

Ask Our Team โ†’

The short version

Text PAC to 65075 โ€” free code in 60 seconds. Give it to your new network. Number moves within one working day.

1

Check your contract

Text INFO to 85075. Free text back with contract end date, any exit fee, and your PAC/STAC codes. No obligation โ€” just information under Ofcom rules.

2

Get your PAC code

Text PAC to 65075. A 9-character code arrives within 60 seconds, valid 30 days. Networks are legally required to provide this instantly and free of charge.

3

Or get a STAC (new number)

Text STAC to 75075 if you want a new number. Triggers the switch without number porting. Old contract ends automatically on switch completion.

4

Sign up and provide PAC

Sign up with your new network and enter your PAC code when asked. The new network handles everything โ€” you don't need to contact your old network separately.

5

Wait one working day

Switch completes in one working day. Old contract cancels automatically. Keep your old SIM in the phone until the new one is confirmed active.

6

Critical: never cancel first

Never cancel your old contract before completing the PAC process. Cancelling first may permanently lose your phone number. The PAC process ends your old contract automatically on the day of switch.

Ofcom rights

  • Networks must provide PAC or STAC within 60 seconds, free of charge
  • No exit fees are charged for switching after the PAC is provided
  • Your number must transfer within one working day of the PAC being submitted
