T mobile internet is the most shittiest thing ive used

Bro, my mom is too fucking lazy to get good wifi, she gets T-Mobile 5g and 5g wifi sucks in suburban areas. My mom doesnt wanna get a gigspeed/gaming Wi-Fi and those wifis work best. Can't even run my twitch streams bc they always disconnect and i cant play world of tanks on my phone without an average of 600 ping to 2600. T mobile. FIX UR PIEICES OF SHITTY ASS INTERNET
