Well if your out in the Fringed area of the service your phone is going to Act as you stated it's going to get Warm as it is constantly trying to connect to the service). I would suggest this if you can get 3G service were your at i would get this App that forces the phone to look for the 3G instead of 4G i can't remember what it's called but i will see if i can find it in the PlayStore.. But it maybe your in a Area that unless you can move around to get Signal you may have to get some kind of Antenna if one is allowed on the Vehicle your in.. And it might this as well if your in a Certain area on the Base the Military might be blocking the Signals i would contact the Base commander and ask...
Good Luck.. Welcome to the Forum.. And thanks for making us Safe.. b33 
I'm sorry Dude i miss read your post it happens when your half a sleep got to amit that. But if your Sim is bad as you mentioned getting a new one is as Easy as Calling Customer service and having one sent out to ya or go to your Local Comm store and they can switch it out. I always tell people Watch how you handle a Sim Card there not a Grenade or something like that were respect on how you handle them is at the up Most important's) But they are very sensitive in one area the Gold area to static Electricity & Oils in our fingers and if there touched a phone doesn't stand much of a chance of working correctly).
So hopefully that's all that is.. and i'll try to be more awake when i respond to your Post or the " Base" commander will have me doing Laps around the latrine..
Take Care..b

The last part of your post could of hit it on the Nail head.. It's hard to tell why those little ******* go bad when i got my First Maxx and was Talking to a Tear 3 tech i asked him on the do's and the don'ts of using my phone and the Sim..because it was all new to me and he mentioned at least 4 times over the course of o couple hours take care how you handle the card while installing it into your Maxx.. I asked him whats really on a Sim Card what does it do and he said it handles every thing from what on your account and plan to making sure the 4G signal gets to the Phone and i said all that on that on a Card that is about the size of Dime maybe a little thinner and he said all that..
