Yeah I do use T-Mobile as well. I don't know if I would ever use T-Mobile's home internet at all. I get pretty good speeds from Comcast. They're a bit more expensive but they work pretty well and they have a reliability rate of about 99% here. There's only been a couple of times where they were having a problem here. And I do think in my own personal opinion in my area T-Mobile would have to densify dramatically in order to provide such a service. During rush hour at times their network crawls. so I agree with you as a T-Mobile user I would be worried. Sent from my Pixel 3a using Tapatalk
As a T-Mobile network user I am concerned. As a computer consultant I think it is good. From a T-Mobile business standpoint it may help justify more rural sites and puts cable companies on the defensive.
Personally I would always recommend that your ISP and cell phone carrier should be different, since most people do not have different ISPs. That way if one goes down you can still communicate with the outside world (in everyday situations).
