Ok... Sorry if this has been asked and answered ,but my HTC EVO 3D is just about shot, and its hard to look around. So heres my question: Metro is now accepting ANY GSM phone as long as its unlocked. They just give you a sim card... I dont want to buy a Metro phone because they are not built well. If I use as Metro sim on a non-metro phone, will it lock certian services, aka Talk to text and stuff like that, that you get free when you flash your phone? Im thinking of getting a Samsung s3 because I like the big screen. If its better to flash should I look for one thats factory unlocked, or just get it unlocked when I get it flashed(or do I need to unlock it when its flashed). I guess Im asking if its better to use Metros sim casrd or just get it flashed. Thanks in advance to everyone who answers!
