"No Sim Card Installed" error
In the past, if I shut the iPad all the way off, then re-booted, it fixed the problem. Now, however, even that trick isn't working.
I've tried re-seating the SIM thinking it might be lose, but that's not the issue.
***? This has become very annoying, and I'm not getting the 3G use I'm paying for when it only works part of the time.
