Activating your phone
All you need to do to activate your Tesco Mobile phone is make a call to any number.
If you’ve upgraded your pay monthly phone and need to use the new SIM, when you switch your phone on the first time you may see it display ‘pay as you go’. Don’t worry, your new SIM will be activated on pay monthly.
If you need a reminder of your new number, it’s in your contract and also in My Account.
Before you make a call
Make sure your SIM card is in your phone – it’ll be on the side of your new phone’s box. Our SIMs are standard size with a pop-out micro or nano SIM, so they work in all phones. Make sure you check your new phone carefully to see what size you need to pop out. You can also check the phone instructions or find your specific device guide
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.
You’ll have to update your number on your new phone:
- Take the SIM out of your phone
- Switch your phone off
- Re-insert the SIM
- Reboot your phone
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.
