To keep your number, request a PAC code from Chattr and give it to Lycamobile.
You can usually give Lycamobile 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.

If you already have your new SIM, continue to Step 3.
If Lycamobile asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give Lycamobile the PAC code using the method below.
Most Lycamobile bundles include international minutes, making it a strong fit if you regularly call abroad.
Lycamobile does not run a credit check, so there is nothing to wait for during sign-up.
Lycamobile offers eSIMs, so you can switch without waiting for a physical SIM to arrive.
3. Give the PAC code to Lycamobile
Once you have your PAC code, here is how to give it to Lycamobile:
- Online: Enter your PAC code at checkout when you order, or email Lycamobile at cs@lycamobile.co.uk or use the live chat on their website.
- Phone: Call 322 from your Lycamobile phone or 0207 132 0322 from any other phone.
4. Wait for your number transfer to Lycamobile to complete
Lycamobile will send the transfer request to Chattr.
Your number should move to your new Lycamobile SIM within 1 to 2 working days.
