ANSWER:
I could top that, your wondering if your wife is cheating because she doesn't answer your call. Before I tell you a story, not because she is not picking up it doesn't mean that she is cheating. You forgot to mention if she works, if she do that will be a no no during working hours unless she is an operator. Or she's probably inside the ladies room, your the one that knows your wife's schedule. Unless the two of you are having problems, then you can question her action.
Contact your cell phone provider.

You should probably call your cell-phone company.. On a different phone of course. :)
Well to know if he's cheating try investigating (example: see if he smells of girl perfume, if you find any items that belong to a girl that's not yours, cell phone text messages....)
Impossible
If your cell phone has a sim card, your phone may say out of service if you are far from a town or city. A phone needs a cell tower to work, so you may get an out of service message if you are not close to cell tower.
