In the past two days my iPad 2 3G has randomly changed the signal status to No SIM. I haven't tried leaving it to see if it changes back, but switching it off and on again immediately resolves the problem.

It's not happening frequently so hasn't become a problem yet but I'm curious if anyone else has had the issue, or if anyone knows why? Could it a sim or iOS issue? I have iOS 5.

Maybe clean the sim card. I have had that happen on some phones and clearing the dust usually does the trick. If that doesn't work you could get a new one.
 
This happened to me a few weeks ago.
No sim just popped up randomly and did not go away.
I tried the following -
Clean the sim, tried a new sim, backup and re-install ios, googled it and tried a few fixes.
I rang apple and they confirmed that i had tried everything, the next step was for a collection and repair or take it back to an Apple Shop, i took it back to the Apple shop and they replaced with a brown box Ipad.

Did it completely stop working at once or did you get No SIM occasionally before it finally died? It's just happened to me a third time in three days and it fixed immediately by switching airplane mode on then off. I would liked know if this problem is likely to get worse though.

Well the message appeared out of the blue - first thing i did was restart then turn off/on cellular a few times and it started working again for a few hours, next day No Sim again, tried the method again and cleaned the sim - it started working for around 5 mins then back to No Sim.. and continued like that for 5 day's until i got it replaced.
So be warned it may appear again!

Thanks, it's just become a lot more common in the past half hour - happened like 10 times and sometimes airplane mode wouldn't fix it. I have a feeling this fault is developing exponentially! What a pain for a 6 day old iPad...

maybe it's about the Card slot,maybe it's about the SIM card itself.try to wipe the slot off,it may get normal back Image

I don't know, but it seemingly hasn't happened for a whole day. I can't really expect Apple to replace it if the fault isn't easily replicable or constant, so I guess time will tell...
 
Same thing

I have the same error. AT&T offered me 190 on trade and apple reset it and did their thing and said I would need a new one if I want 3G. Works fine with wifi. Probably gonna sell on Craigslist. Seems to be ok market for 64g
