T-Mobile was good in SoCal but now I'm out in nowhere and at&t is better here (T-Mobile here probably would take me 5-10 for anything too). I spent 4 weeks in Dallas and didn't have issues with reception. I love Dallas. After 4 weeks of eating brisket everyday, I came home and bought a heavy duty smoker.This is exactly why I use it. $20/mo to make up for my horrible Tmobile service. Before I had the car wifi it'd take about 5-10 minutes for Google Maps/Spotify/etc to work because of the density of where I'm at (Downtown Dallas).
I really need to get off tmo unless their 5g is legit.
