I've cut the cord over a year ago and exclusively use Tmobile wireless.
I'm a network engineer/architect, work 100% remotely and never had a problem with my internet
I have read somewhere that since Tmobile internet became so popular that new subscribers are not getting the same bandwidth as the legacy user. It's currently 12;58 and my download speed is slightly over 200mb. I have seen speeds up to 300mb. My location is in the suburbs of Atlanta. At any given time 3 or more 4k TV"s are streaming along with other IOT devices, no real issues. Since I'm a Tmobile phone customer, internet costs me $30 monthly along with Netflix, AppleTV and Paramount+..
You can't beat that with a stick.....
Enjoy the Music
