We have T-Mobile cell service and have no problems with it. But we tried the home internet and it was terrible. No idea why. We returned it during their trial period.
We have Spectrum now, but just the minimum. We don't have any gamers here anymore... just do live streaming and other basic internet stuff. It's fine. And I recently called and got a discount. But we have had TWO separate fiber-optic lines run down our street in the past few months -- one is Point, other is Alta. So there's some competition at least, finally.
