Moving your number from one Tesco Mobile SIM to another

Close Article
If you want to move your number to a different Tesco Mobile SIM then you can use our free text service to do it. You might need to do this if you’ve got a new device that uses a different size SIM.
Before you do, make sure you save your contacts to your phone and back up anything important (like photos or videos), as anything on your SIM won't be transferred.
  1. Text SWAP to 23424 from your original SIM card. It’s free
  2. We'll text you letting you know your number will be moved
  3. Then we’ll text you asking you to reply with the serial number of your new SIM card – this is either a 13 or 19 digit number
  4. We’ll text you asking you to put your new SIM into your phone. Your number will be on your new SIM within 24 hours
