My iPhone started displaying a "No Service" message a few days ago. When it didn't go away, I called the ATT Wireless people. Here are the easy steps to cure the problem:
Hopefully, service comes back.
While I was waiting for someone to help me, I started the process on the Apple Support site to get my $100 Apple Store Credit for early iPhone owners. As soon as the iPhone rebooted, the confirmation message came through. Nice way to check the connection!
Thanks! That worked for me too. The only thing that I might have done to trigger the bad behavior was spending all day yesterday in an area with no service.

Posted by: CB on January 26, 2008 1:19 PMThanks for the helpful post! Ran the battery down today pretty low for it to function properly. This fixed it right away.

Posted by: jose on March 5, 2008 8:52 PMRather than a data reset, I did a direct reboot (described in the iphone user guide)
Press and hold both the Sleep/Wake button and

I did hard reset, but didn't work. Finally,

Thanks a bunch. I couldn't figure out what was going on.

Posted by: emily on April 17, 2008 4:29 AMThanks a lot - I had emailed AT&T and their email back to me was that they would contact me within 2 days!! I re-set and had Phone Service again immediately.
Posted by: Victoria Lemaster on April 20, 2008 7:22 PMI was running on a 1.1.4 3.9 bl and i solved my problem by reflashing the bl to 4.6 and downgrading the baseband to 04.02.13_g and installing firmware 1.1.2 ... i then unlocked using geohot method and now my phone works perfectly.
i was getting random no service about twice a day and sometimes it was for about an entire day.
I hope this will help ... sry for my english

Posted by: Patrick on July 12, 2008 2:13 AMHi there ,i upgraded my iphone to 2.0 by total accident as i know better . I went through the correct procedure to restore it back to its unlocked status , but now i have no service , and there is no carrier tab in the settings menu ????!!!! Any suggestions , or possible solutions !!!?? Thanks very much for your time !!!!!!
Posted by: Paul on July 17, 2008 10:22 PMNo carrier tab is necessary. On the iphone, go to Settings > General> Reset (all the way at the bottom) and click Reset Network Settings.
