  1. I recently got a zte g n290 phone,TV phone, but its locked to a particular network/ service provider. I got some info on how to unlock it and did, before I did it said invalid sim but now it goes through and now it searches and then says Emergency / select a network. I've tried other codes and stuff.
    If there is any other way that I can do this please inform.
