I can't receive incoming calls and sms on my iPhone 4 after the 3G connection has been activated and used actively by me. Outgoing calls and messages do work and as long as I use the Wi-Fi connection everything's fine but the problem appears after switching to 3G. Any help? Thx in advance!
iPhone 4, Operating System iOS 4.3.3.
Who's your carrirer? If it is Verizon, you can't use 3G and Voice at the same time.
oh I forgot to say that I'm using the phone in Germany. I haven't found any restraints so far concerning the use of 3G and Voice at the same time. Anyway, do you think it is rather a provider than a hardware problem?
I think the next step is to do a reset by holding the sleep and home buttons down at the same time until the Apple logo appears. If you haven't done this before, keep holding the buttons when the turn off slider appears. The screen will go black and after what seems like an eternity, actually several seconds, the Apple logo will appear. When the logo appears, release the buttons.
i have tried this 3times already i even reset my network settings, but still the same. it just suddenly happen to me today the rest of the days it still working find when my 3g is turn on pls help:(
