[iMore Question]

My daughters iPhone 4s loses cell service, nearly imidiatly if i try to swich on 3g.
With 3g on i can't even make a call.
It is a clean IOS 7.03
I already tryed network reset, software reset, flightmode off and on.
I tryed to change the antennacable. Nothing helps.
I have searched around, to find similar problems, but it doesnt seem to be an known isue.
Does anybody have an idea, what to do?
Best Regards

Call your service provider to see if they can troubleshoot the problem from their end.

Now i talked to the ISP, and they claim, that it is not a fail in there systems.
I also tried a colleges simcard from an other ISP, using a different network...
But... nearly same problem, except that signal drops, instead of disappere.
Still no phonecalles, when 3g is turned on.
Doesen't that sound like a hardware falior.

It could indeed be a hardware problem, but before you take it to a nearby Apple Store to have one of the geniuses look at it, I recommend you connect it to iTunes, backup your data, put the device in DFU mode and then restore and set it up as new via iTunes. Afterwards, your phone should auto-detect 3G or LTE, depending on your wireless provider and your wireless plan. If not, make an appointment with the nearest Apple Store.
