A Nokia SL3 is short for "SIM Lock 3." This means your Nokia phone has a lock protection feature that prevents you from switching providers. If you received your Nokia SL3 through the mail or from an online store, it may have come with a lock on it. To switch providers, you will need an unlock code. Your mobile provider will help you generate an unlock code using your phone's International Mobile Equipment Identification (IMEI) number. It is up to you to locate this number from your phone.
