This guide explains how to switch from Talk Home to Grade Mobile and keep your mobile number.

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

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

Talk Home and Grade Mobile both run on EE's network, so your coverage will not change when you switch. You are changing provider, but your signal will still use the same network.

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

You can usually give Grade Mobile your PAC code when you order, or after your new SIM card or eSIM has been activated.

1. Request a PAC code from Talk Home

Switching from Talk Home and keeping your current phone number is easy. You don't need to memorise a new number or update all your contacts!

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

Text "PAC" to 65075 from your Talk Home phone. You will get a text with your code. This is a free service from Ofcom (the UK's communications regulator).
Phone: Call 579 from your Talk Home phone. Their customer support team will help you get your PAC code.
Online: Log in to your Talk Home account online. Go to the "Porting" section and click on "Porting Out" to get your PAC code.

Requesting a PAC does not cancel anything. Your Talk Home plan carries on as normal until the code is used, and if you never use it, it simply expires after 30 days.

The text with your PAC will also show any early exit fees you would pay or credit you would lose by switching, so check it before you hand the code over.

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

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

Grade Mobile is best known for refurbished phones, and you can bundle a refurbished handset with its SIM plans.

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

3. Give the PAC code to Grade Mobile

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

Online: Enter your PAC code at checkout when you order, or give it to Grade Mobile via their online contact form or by emailing contact@grademobile.co.uk.
Phone: Call Grade Mobile on 0808 175 2343 and give them your PAC code.
