If you've purchased a phone from another network and want to use it with your Tesco Mobile SIM, it might be locked.
Step 1: Check if Your Phone is Locked
Insert your Tesco Mobile SIM card. If it doesn't work or shows an error, the phone is likely locked to another network.
Step 2: Get Your IMEI Number
Dial *#06# to display your phone’s 15-digit IMEI number. Note it down.
Step 3: Contact Your Current Provider
Get in touch with your current provider to request an unlock code.
