There's a world outside of Texas you know...
Come to the Northeast. I can drive from Portland, Maine to Washington DC and NEVER loose LTE on VZW or AT&T. I can stream music perfectly.
TMobile? Mostly EDGE/GPRS. You get some HSPA when you hit Boston and then loose it in CT until you hit Hartford. Then it's gone until NYC. Then between NYC and DC, it is EDGE until Philly, and then between Phily and DC, it's gone once again.
I've done this drive many many times. My car runs on TMobile service. Its GPS can't buffer maps when on EDGE, which is most of the time. The built-in WiFi hotspot is worthless also. I wish there was a way to tether my AT&T or VZW connection to my car.
TMobile has more EDGE out there than HSPA. In fact, VZW and AT&T has more LTE than TMobile has HSPA. Ridiculous when you know that TMobile has been deploying HSPA for almost 5 years and LTE deployments started back in 2011.
Fact of the matter is that they haven't pledged any sort of updates for all this GPRS/EDGE. Legere is too busy spewing his BS to all the bottom dwellers, who love his kool-aid.
And no, I am not paid by AT&T or VZW. I pay for AT&T and TMobile. And get VZW from work. I am well-aware of what's going out there. If you don't care to admit, then I'm sorry.
