let me know if you find something that works. I am exactly in your boat, I can't figure this out. i've done everything as well and still get "no sim card installed".

This happened to me three times in the past three months. I solved it each time by rebooting (holding down home button on front and power button on top right). This last time it took a few tries.

Oh well hope its sorted tomorrow.

I live in the SF Bay area, which has notoriously bad 3G network service, and my iPhone is about 9 months old. I went to sleep listening to music on my iPhone and woke up to the "No SIM installed" message.

I'm in favor of starting with the least invasive solutions first, so I did a few hard reboots. It didn't work.

I read about resetting network connections as a solution and was about to do that next when I read somewhere to try putting the phone into "Airplane Mode" and doing a hard reboot, then taking it off "Airplane Mode". THIS WORKED for me. As soon as I took it off "Airplane Mode" it redetected the network.
