Just insert your new SIM into your device and it will activate automatically within 24 hours, but often sooner
If you need to activate your SIM card online you will need an EE signal on your old SIM so you can receive a text.
During the activation process you will be asked for your new SIM serial number. It’s located underneath the barcode on the letter that came with the new SIM (see below). You will need to enter a 14 digit number so it’s important to include the 2 numbers in brackets at the end.
A few points to bear in mind…
If you have upgraded your phone and your old SIM card is the correct size you can continue using it
When upgrading from an Orange or T-Mobile plan to EE you won’t be left without service, your old SIM will continue to work until your number transfer completes
If your new SIM card fails to activate for any reason please get in touch with customer service
I hope this helps you get started, thanks for reading.
