This guide explains how to switch from Talkmobile to Chattr and keep your mobile number.

Most number transfers complete within 1 to 2 working days once Chattr has your PAC code.

If you want a new number instead, text STAC to 75075 and give the code to Chattr.

To keep your number, request a PAC code from Talkmobile 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 Talkmobile

Here is how to get your PAC (Porting Authorisation Code) from Talkmobile:

  • Text: Text "PAC" to 65075 from your Talkmobile 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).
  • Online: Log in to your Talkmobile account and go to the Switching section to request your PAC code, or use live chat on their website.
  • Phone: Call 5888 from your Talkmobile phone (free) or 0333 304 8064 from any other phone (charges may vary). Support is open Monday to Friday 8am to 8pm, Saturday 9am to 6pm, and Sunday 10am to 5pm.

2. Order a SIM only deal from Chattr

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 Talkmobile.

Your number should move to your new Chattr SIM within 1 to 2 working days.
