Unlocking a LG GS390 Prime from AT&T only takes an unlock code and a few steps. An LG GS390 Prime unlocked will work on any SIM card based phone network, rather than just AT&T. In order to fully unlock your LG GS390 Prime you will need to an unlock code. This unlock code will remove the SIM lock that comes on many SIM based LG cell phones by default. Once this SIM lock is removed, you will be free to use your LG GS390 Prime with any GSM or SIM card based mobile phone carrier you wish.
Getting an unlock code can be free often if you cann up your LG GS390 Prime phone carrier’s support line. Request an unlock code and in exchange they will need your phone’s IMEI number, which on a LG GS390 Prime you can simply get by typing *#06# and hitting send or enter on your keypad. Your LG GS390 Prime’s IMEI number is used to calculate your LG unlocking code. If you do not currently have a carrier or cannot get a free one, then I would suggest you review some of the unlock code websites I have provided later in this guide.
