My iPhone says it's not activated?

I have a iPhone 4S 16 gb, after I updated my phone to iOS 7 it says it's not activated. A day later it worked fine for about a day then it kept on again and it's been about 3 days and it still doesn't work. I've tried turning it off and on, take out the SIM card and still nothing.

  • Why is my iPhone not getting activated? I updated the iOS on my iPhone 3GS from 4.1 to 6.1 or something like that. Now when the phone started i reached start-up up to the Wi-Fi network selection screen. After that it a screen appeared telling me to wait while the iPhone is being activated.iTunes is also not showing anything. Then suddenly the iTunes screen says it can't be updated, please try again later. I have tried several times but it's not working.
  • Why factory unlocked iphone 4s is showing that the iphone is not activated? I bought factory unlocked iphone 4s on ebay for my sister-in-law who is in europe. And the seller assured that it is factory unlocked and will work perfectly. I have non activated sprint sim card and when i inserted it in to the iphone it showed that "the iphone is not activated.contact the carrier". What does it mean? Does it mean that the phone is not factory unlocked?
  • My iphone says i'm connected to Wi-Fi but when i try to run something it says i'm not connected? My phone shows signal, it has a check mark by the device but when i try to open an app it says can't find a connection.
  • My Iphone isn't working to an extent, says not activated? My Iphone works like normal you know, making phone calls, texts, and surfs the web and all. What isn't working is the Facetime, Imessaging, and installing profiles under the Settings. When ever i try using facetime or installing a profile it says waiting for activation and then says Iphone isn't activated? I have verizon and I went to them and they said I probably have to go to apple, any suggestions or ideas.
