So I have a rather interesting problem. I am able to turn on tethering, connect my iphone 5 with ios 6.0.2 and use it no problem. the problem arises when I turn off tethering and dont use it for a couple hours. When I go to activate tethering, it will boot me out of the screen and tell me that I have to contact my provider to set up tethering. to fix this, all I have to do is "reset the network settings". the problem is, I have to do this multiple times a day.
I have switched my sim card, got Apple to do a hardware swap (theyve given me another brand new iphone 5 as mine was only 1 week old) and have done multiple reinstalls from scratch (not using my backed up data) and have hard rebooted countless times. I have also contacted my provider and they have taken off and reinitialized the tethering service. It continues to happen.
I have read many boards but havent been successful in finding someone else with the same problem as me.
If anyone has any idea what is happening and know a fix, please share!
