Mobile users are now able to switch networks by sending a single text and take their old number with them within 24 hours under new regulator rules.
Customer had to phone their mobile provider when they want to switch to a new mobile firm. They were given a porting authorisation code (PAC) to give to a new provider if they wanted to keep the same phone number.

The new way to switch networks comes after customer complaints about it being difficult to switch providers. Ofcom have said the new text-to-switch process will make it easier and quicker for customers to leave their mobile company.
Ofcom’s consumer group director Lindsey Fussell said: “Breaking up with your mobile provider has never been easier thanks to Ofcom’s new rules.
“You won’t need to have that awkward chat with your current provider to take advantage of the great deals available.”
The process:
- Customers who want to switch and keep their existing phone number text “PAC” to 65075 to begin the process
- Their existing provider will respond by text within a minute
- They will then be sent their switching code (PAC), which will be valid for 30 days
- The provider’s reply must also include important information about any early termination charges or pay-as-you-go credit balances
- The customer then gives the code to their new provider, and this company must arrange for the switch to complete within one working day
- While most people want to keep their mobile number when they switch, about one in six do not. These customers can text “STAC” to 75075 to request a “service termination authorisation code”.
Ofcom have now banned mobile providers from charging for notice periods running after the switch date. Ofcom has estimated that it will result in a saving of £10 million a year.
Customers need to give their new provider the PAC or STAC number, by doing this their old and new mobile companies can make sure there is no double payments.
