Unlock your Tesco Mobile phone
Checking if your phone is unlocked
If you’ve got a Tesco Mobile phone and you want to use another network’s SIM card in it, just put the SIM into the phone. If it doesn’t work, it’s probably locked.
How to unlock your phone
We don’t charge to unlock Tesco Mobile pay monthly phones or Tesco Mobile pay as you go phones over 12 months old. You just need to complete an online unlocking request and then follow the instructions. We’ll text you within 7 days with the code and a link. Click on the link and then follow the instructions to unlock your device.
We can unlock
- Any phone that’s locked to the Tesco Mobile network, as long as it’s not barred
- Tesco Mobile pay monthly phones that don’t have a Tesco Mobile SIM card
We can’t unlock
- Phones that are locked to any other networks
- Phones that have just been launched – you may have to wait up to 12 months
- Phones that weren’t supplied by Tesco Mobile
If you don’t know if your phone is pay monthly or pay as you go, we can check for you when you make your unlocking request. Then we’ll text you to let you know what to do next.
Paying to unlock your phone
If you’ve got a pay as you go phone less than 12 months old, you’ll need to pay £10 to unlock it.
To pay, just top-up the Tesco Mobile number you gave to us and we’ll take the £10 payment from the SIM card within 24 hours.
To request an unlock code, you’ll need a pay as you go SIM card with an active number. If you don’t have one, you can request a free Tesco Mobile SIM. Once it arrives and you’ve activated it, call 4444 free to top-up.
Once you’ve topped-up, complete an online unlocking request and follow the instructions. We’ll text you within 7 days with a code and a link. Once you receive it, just click on the link and then follow the instructions to unlock your device.
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.
