| T-Mobile | 103 W Main St | Along I-30 between Greenville and Rockwall, I always lose all service around Royse City. Just before and just after, i will usually resume 4G, but it is super slow. Like I can't even load a webpage on 4G anywhere with T-Mobile. If I don't have LTE coverage, then forget using any data. | 2015 |
