Uswitch tips
How do I switch and keep my number?
1. Choose your new deal
Select a deal below and click through to the network’s site.
2. Get your PAC code
You’ll need a special code to keep your number when you switch. It's quick and free:
Text 'PAC' to 65075 to receive your code.
3. Give the code to your new network
Contact the new network after signing up to provide them with your PAC code, which will begin the process and will automatically cancel your previous plan. Alternatively, you can enter the PAC code when signing up on the network’s site.
Should I buy a SIM-free phone and pair it with a SIM only deal?
Buying a phone outright, also known as SIM-free, can be a smart way to save money in the long run, especially when paired with a good value SIM only deal. It gives you more flexibility and means you're not tied into a lengthy contract.
If a brand-new handset is out of budget, consider a refurbished phone. These professionally tested and restored devices often look and perform like new, but come at a much lower price.

Uswitch services are provided at no cost to you, but we may receive a commission from the companies we refer you to. If a deal is "promoted" on Uswitch's tables, then it has been lent additional visibility as a result of us securing exclusivity on a great deal, or a commercial agreement to showcase what we believe to be market-leading value to consumers.

Until 2024, many mobile networks have increased contract prices in line with inflation. Starting in January 2025, Ofcom will introduce a ban on inflation-linked price hikes for new contracts. Future price changes will need to be set and fully disclosed in pounds and pence.
