Horrible Signal/Service

I recently switched back to T-mobile due to cost of home internet & everything being pretty ridiculous else where. I am sadly regretting this choice! I get good home internet service only for about 4 hours a day. The rest of the day it is buffering constantly. I have to reset the internet password on my electronics multiple times a week as well because the internet goes out. I also have horrible cell service where I live. Inside my house it's decent but once I leave my home I lose ALL signal! I can't open apps & I have a difficult time making calls because there is no service! I am seriously breaking my contract or whatever to find a better service that I can actually use my phone when I am in town.
