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

You can usually give Talk Home 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 Talk Home

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

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

Talk Home specialises in international calling, with international minutes to around 50 destinations included on its bigger plans.

3. Give the PAC code to Talk Home

Once you have your PAC code, follow these steps to give it to Talk Home:

Phone: Call 579 from your Talk Home phone. Their customer support team will help you get your PAC code.
Online: Give Talk Home your PAC code via your account area.

Talk Home will then handle the transfer of your number. Give them your PAC code within 30 days of receiving it — after that it expires and you will need to request a new one from Chattr.
