I'm always getting drop calls and a weak signal inside of my house. Most of my calls I recieve goes straight to my voice mail and when I do connect, it stays connected for only a minute. This is with wifi on or off but with wifi off, it's horrible, can't even dial out. Had to get a landline just to make and recieve calls. The coverage in my area is terrible and I've conducted all troubleshooting options that's listed. I'm out of options at this point, any help is appreciated. P.S. I've had an Iphone 5, 6, and now 7 and they all had the same issues... dropped callls and a bad signal!!!
