Tesco mobile UK does not require many processes to get your new sim up and running. To activate your Tesco mobile sim, do the following:
- Inside your Tesco SIM into your mobile phone.
- Place a call to any number.
- 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.
- For iPhone users, You’ll have to update your number on your new phone.
If your phone still shows no service or network after you have done all these, there could be a temporary problem with the signal in your area. Alternatively, you can use our coverage checker to find out. If you’re still having problems calling, please contact Tescomobile.com.
