I would not recommend tmobile, well maybe to my worst enemy.. they throttle so bad it makes my device useless. Hulu, prime and Netflix all lag. Switching to cricket. So I can compare them. Swap in my cricket Sim and it's like the fog lifts and everything runs as it should. cricket throttles too.. but I don't notice it. cricket is cheaper too. I Feel sorry for sprint customers, Cricket 4G is way faster then Tmobile 5G. OH. I have never gotten this app to work. Galaxy tab S6. and Galaxy Note 9.
