Unlocking your phone to join Tesco Mobile

If you want to use a phone or tablet from another network on Tesco Mobile, you might need to get it unlocked.

To find out if it’s locked to your old network, just put your Tesco Mobile SIM card into your new device. If it doesn’t work, it’s probably locked.

To unlock your device, just call your old network, but please note that they might charge you an unlocking fee.
