Ah nice.
So you mean the
WCDMA has to be unlocked every time you reboot. And WCDMA is hspa/hspa+/hsdpa ? Sorry for being a noob at frequencies lol.
WCDMA is the technology, and what they call umts which is also hspa.
So AT&T gs3's have lte which does work on T-mobile when unlocked. And it has 700mhz and class 17 /2100 for lte, according to gsmarena.
As soon as the sim is unlocked the phone works on both the refarmed towers (they run on 1900mhz) and LTE (running on 1700/2100) those frequencies are native to att as well which is why they work.
I'm not sure what class 17 means though. Since you're in Jax like me at least I know that it has working lte lol.
I am not sure what class 17 is, do you mean Band 17? if that is the case that would be the lte 700mhz that is native to att in most markets.
Another question to people, is the 1700 band AWS and is the 1900 band UMTS? Because I have an Amaze unlocked and I think T-Mobile refarmed the frequencies.
1700/2100 is called AWS 1900 is called PCS The UMTS is part of the technology.
And yes jax is refarmed though only in some areas, its difficult to roll it out across the entire city.
If that is the case T-mobile has definitely refarmed Jacksonville to 1900 hspa+.
Thanks for the help guys.
