Installing your new SIM
Swap your SIM
Once everything’s ready, and you’ve read your instructions, it’s time to swap your SIM.
Let’s do this thing!
Your new SIM card is attached to your letter. As your letter is
written specifically for you and your handset, it’s important that you
read it through before you put your new SIM in your phone.
Remember, if you’ve got multiple SIMs to swap in your
household, make sure you put the correct SIM in the correct
phone. Your letter will tell you which SIM is linked to which phone.
There are two ways to request a switch date if you’re asked to
- By texting ‘SWITCH’ to 789255 from your old SIM
- By accessing your account
Note: It’s important you carry on using your old SIM until the date
we give you to switch.
How to swap your SIM
3. Insert your new SIM
Once you’ve popped out the right sized SIM just put it into your phone.
4. Restart your phone
You can now turn your phone back on with the new SIM card inside. It may take up to 10 minutes for the new SIM to register on the network.
Your phone might ask you to enter an unlock code once you’ve swapped the SIM. This is a one-off code that isn’t your personal passcode (don’t enter this as you may lock your phone). You can find your unlock code in the letter we sent with your SIM. If your code doesn’t work, please don’t keep trying. You can request a new unlock code by clicking the button below.
