Why does my iPhone 4 say No Service but also 3g works and so does SMS?

Since this afternoon, my iPhone just said No Service. 3g is also show, and SMS works fine! What's wrong? I have ATT if it matters

It's probably a glitch, try turning off your phone. & if that doesn't work try resetting it with iTunes.

You have ATT… Thats what's wrong! LMAO

reboot the phone, all better now? If not, call ATT to make sure there's no tower issue in your area… If no issue, then be transfered to Apple for an iOS bug… An itunes restoral may be needed

Does anyone know what's going on or how to fix it? I've already tried restarting my phone and the network settings.
  • Why does my iPhone say no service? - 2 Well I took a trip to Wisconsin and my Verizon iPhone stopped working the minute I got here! It keeps saying no service then it will search for about 5 min then say no service! There's no Verizon towers anywhere! And I don't have roaming on because I fear the charges? Well I don't know does Verizon charge for roaming?
