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

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

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

To keep your number, request a PAC code from your current network 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 your current network

You do not need to change your number when you join Grade Mobile.

Request a PAC (Porting Authorisation Code) from your current network using one of these methods:

  • Text: From your current phone, text "PAC" to 65075. You will receive a text back with your code within a minute. This is a free service from Ofcom (the UK's communications regulator).
  • Online: Some networks will allow you to log in to your current online account and request your PAC code.
  • Phone: Call your current provider's customer service phone number from your current phone.

Requesting a PAC does not cancel anything. Your current 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.

2. Order a SIM only deal from Grade Mobile

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 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.

4. Wait for your number transfer to Grade Mobile to complete

Grade Mobile will send the transfer request to your current network.

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

If your new network asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give your new network the PAC code using its transfer process.

3. Give the PAC code to your new network

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

  • Online: When you order your new SIM card online, you can enter your PAC code.
  • Phone: Call your new network's customer service number and provide them with your PAC code.
  • In-store: If your new network has a store you can visit a store, and a staff member will help you transfer your number using your PAC code.

Your new network will handle the transfer. 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 Grade Mobile.

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

4. Wait for your number transfer to your network to complete

Your new network will send the transfer request to Grade Mobile.
