Sorry guys I was just clarifying the question of whether or not it would run on any GSM network.
To do so you just need simply to unlock the phone by purchasing an unlock code online. There are numerous sites that sell and email the code to you within a 24 hr period. I just Googled unlock "LG Optimus L9 P769" (just enter your model). I purchased the unlock code for $7.
Then once your phone is unlocked just purchase sim card from GSM provider you would like to use. Insert sim into phone (find sim slot under battery) and activate phone with new service provider.
*There are two variants of the p769. T-Mobile and MetroPCS. Make sure you get the correct model info from your phone.
