LTE is for Internet., Not voice. Metro uses CDMA for voice and T-Mobile uses GSM for voice. The question is still unanswered.
The International version of Galaxy s3 has CDMA and GSM. I was trying to find out if Metro had GSM removed.
Theoretically, unless they butcher the hardware, the Galaxy 3 could work with ANY Carrier. And that's how most would prefer, but we all know how greedy corporations wanna put a chain and ball on everyone.
So does anyone know if the MetroPCS Galaxy S III will have GSM and CDMA in it? We all know that it has LTE. Geez, even Sprint is changing to LTE from WiMax.
