Activate your phoneClose Article
All you need to do to activate your Tesco Mobile phone is make a call to any number.
Once you’ve done this, we recommend you register your phone's unique IMEI number on the Immobilise website. This might make it easier to recover if it’s stolen.
If you need a reminder of your new number, it's in your contract and also in My Account. Want to keep your old number?
Before you make a call
Make sure your SIM card is inserted. Our SIMs are standard size with a pop-out micro or nano - so they work in all phones.
If you’re a SIM only customer, make sure the phone you’ll be using works with a Tesco Mobile SIM – you might need to ask your old network provider to unlock it.
If you’re a pay as you go customer, you’ll need to top-up first.
Getting to know your phone
Our device guides have lots of step-by-step information to help you make the most of your new phone.
If your phone shows no service or network, there could be a temporary problem with the signal in your area - you can use our coverage checker to find out. If you’re still having problems calling, please contact us.
