This weekend I caught some decent LTE coverage on 10th street in McAllen. Speeds and strength varied a whole lot as I drove down 10th, but from Dove down to around Business 83 things were pretty solid. Screenshots are both from the same location (Lone Star BBQ, about half a block south of Nolana.)
I've also been able to get an LTE signal south of Business 83 over the past couple of weeks, but never with working data.
