To keep your number, request a PAC code from iD Mobile and give it to Chattr.
You can usually give Chattr your PAC code when you order, or after your new SIM card or eSIM has been activated.
1. Request a PAC code from iD Mobile
Here is how to get your PAC (Porting Authorisation Code) from iD Mobile:
- Text: Text "PAC" followed by your date of birth as DDMMYY to 65075 from your iD Mobile phone (for example, PAC 010190). You will get a text back with your code within a minute. This is a free service from Ofcom (the UK's communications regulator).
- Online: Log in to the iD Mobile app or My Account online and go to Plan, then Leave iD, then Get PAC Code.
- Phone: Call 0333 003 7777 and follow the cancellations options. You will need your iD customer service PIN from your welcome text or email.
Your iD Mobile data rollover balance is lost when you leave. It cannot be transferred or refunded.
2. Order a SIM only deal from Chattr
If you have not ordered yet, compare current Chattr SIM only deals below.

If you already have your new SIM, continue to Step 3.
If Chattr asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give Chattr the PAC code using the method below.
Chattr includes EU roaming at no extra cost, and everything is handled online rather than in-store.
Chattr does not run a credit check, so there is nothing to wait for during sign-up.
Chattr offers eSIMs, so you can switch without waiting for a physical SIM to arrive.
3. Give the PAC code to Chattr
Once you have your PAC code, here is how to give it to Chattr:
- At checkout: Enter your PAC code when you order your Chattr SIM.
- Email: If you have already ordered, email your PAC code and the number you are transferring to hello@chattr.co.uk.
4. Wait for your number transfer to Chattr to complete
Chattr will send the transfer request to iD Mobile.
Your number should move to your new Chattr SIM within 1 to 2 working days.
