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

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

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

This switch will take you from O2's network to Vodafone's network. Coverage may differ in some areas. Check Lebara's coverage checker before switching.

To keep your number, request a PAC code from Chattr and give it to Lebara.

You can usually give Lebara 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 Lebara

If you already have your new SIM, continue to Step 3.

If Lebara asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give Lebara the PAC code using the method below.

Most Lebara plans include international minutes, rising to unlimited on the top plans, so check the country list covers who you call.

Lebara SIMs must be activated within 30 days of ordering or the plan and any promotions lapse.

Lebara does not run a credit check, so there is nothing to wait for during sign-up.

3. Give the PAC code to Lebara

Once you have your PAC code, here is how to give it to Lebara:

  • Online: Enter your PAC code at checkout when you order, or complete the Port In form on Lebara's website afterwards. An advisor chat will take your PAC and the number you are transferring.
  • Phone: Call Lebara on 5588 from your Lebara phone or 0207 031 0791 from any other phone.

4. Wait for your number transfer to Lebara to complete

Lebara will send the transfer request to Chattr.

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