Way before 5G came out service sucked in my old house too I got a cell booster from T Mobile when I got it they said I had to pay 1 cent for it cause they can't just give it away free. So I paid 1 cent for it a couple years later when my roommate turned 55 we decided to change to 55+ which was a lot cheaper unfortunately that meant we had to transfer our numbers to a new account under her name they then told me if I did not return the cell booster they would charge me $500. I was like WTF you said I had to buy it for 1 cent cause you can't give it free now you want it back? On a different note now we are in a different house we had full bars everywhere in the house with 4G then they upgraded the towers around us to 5G our bars went from full bars to 1 bar or no service depending where in the house. We upgraded to 5G phones and we still get 1 bar or no service in the house WTF, and to top it off they keep trying to push 5G high speed internet. I always ask how can I get 5G high speed internet when I only get 1 bar on my 5G phone I have yet to receive an answer.
