To keep your number, request a PAC code from Chattr and give it to 1pMobile.
You can usually give 1pMobile your PAC code when you order, or after your new SIM card or eSIM has been activated.
1. Request a PAC code from Chattr
Here is how to get your PAC (Porting Authorisation Code) from Chattr:
- Text: Text "PAC" to 65075 from your Chattr phone. You will get a text back with your code within a minute. This is a free service from Ofcom (the UK's communications regulator).
- Email: Email Chattr at hello@chattr.co.uk to request your PAC code.
Chattr is an online-only network with no stores or phone line.
2. Order a SIM only deal from 1pMobile
If you have not ordered yet, compare current 1pMobile SIM only deals below.

If you already have your new SIM, continue to Step 3.
If 1pMobile asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give 1pMobile the PAC code using the method below.
1pMobile's 30-day Boost bundles have no contract, and if you use up your data the excess charges at 1p per MB instead of cutting you off.
1pMobile does not run a credit check, so there is nothing to wait for during sign-up.
1pMobile offers eSIMs, so you can switch without waiting for a physical SIM to arrive.
3. Give the PAC code to 1pMobile
Once you have your PAC code, here is how to give it to 1pMobile:
- Online: Enter your PAC code at checkout when you order, or log in to your online account, or contact support by email or live chat.
- Phone: Call 03333 442278, 9am to 5pm Monday to Friday, excluding public holidays. Calls are charged at your standard network rate.
4. Wait for your number transfer to 1pMobile to complete
1pMobile will send the transfer request to Chattr.
Your number should move to your new 1pMobile SIM within 1 to 2 working days.
