NO RECEPTION!

I LOVE our new apartment, but I can't stand that we have NO reception with our cell phone! haha... The phone has to work so hard to find towers that the battery honestly dies in a couple of hours and we receive no calls that we are supposed too.. When I want to talk with people I have to find a spot where reception can be found, set the phone down, and i cant move while I talk. it will even die if i just move in front of the phone in the wrong way... what do i do?!?! AHHHHHHH
