No Service on my iPhone 4s on Tmobile?

For the past few days my iPhone 4s has had trouble connecting at all to tmobile, ee, 3g or even Wi-Fi. It is only in certain places that it does not connect at all (one place is my house) but anywhere else I have really poor connection. Any idea why this could be and how I could fix it?

Added (1). Also, turning it on and off does not help.

I have had this phone for nearly a year and I have never had problems before.

You either have a bad radio or poor reception due to terrain, building contruction, elevation, BP, etc etc etc

call Tmobile and report the issue. If the iphone is to blame, you get another free warranty… If you live in a bad area… Suck itup and deal with it… Or leave tmobile.lmao

  • Would an iPhone 3gs pick up 4g service on tmobile? I have a jailbroken, unlocked iPhone 3gs that I used to use with tmobile. Before, I only received EDGE service no matter where I was. This was before tmobile began carrying the iPhone on their network. Right now I have an LG Optimus L9 and it has 2 gigs of storage on it so I'm wanting to change to the iPhone if the phone will get better service than EDGE. So, now that tmobile carries iPhones, will mine receive better service than before tmobile carried iPhones?
