What do I need to do when I get a new SIM?

What do I need to do when I get a new SIM?

Here’s what to do when you get sent a new SIM:

  1. 1

    Pop the SIM into your device

  2. 2

    Activate your new SIM

    You only need to do this if you’ve upgraded and been sent a new SIM. Or ordered a new one because your old one no longer fitted your device.

  3. 3

    Wait for a signal and the EE symbol to appear on your screen

    This can take up to 24 hours but is usually much quicker.

And you’re all set up! We won’t even send an activation text, just a few network updates.

Good to know

If you’re using an Apple device, you may also need to refresh iMessage so it connects with the right number. Just:


    go to Settings > Messages


    turn iMessage off, wait 10 seconds and turn iMessage on again


    go to Settings > Phone and make sure My Number shows your correct mobile number 


    tap My Number and type in your correct number if the above steps don’t work

What information do I need if I have to activate my SIM?

What information do I need if I have to activate my SIM?

As we said above, you’ll only need to activate your SIM if:

  • you’ve upgraded and been sent a new SIM
  • ordered a new SIM because your old one was the wrong size for your device

If that’s you, we’ll ask for three things:

  1. The reason you’ve got a new SIM
  2. Your current phone number - So we can text you a security PIN
  3. The serial number of your new SIM - You can find this on the back of the SIM or under the barcode on the letter we sent with your new SIM

And that’s it!
