Sudden "No SIM" error while the SIM is in there!

[wildonrio]

I restarted my phone and when it came back on, it said No SIM all of the sudden. The SIM was definitely still in there. I restarted the phone over and over and it still said No SIM. Then I took the SIM out and put it back in perfectly, still No SIM. So basically on iDay 2 the rest of the day my phone was out of commission. It wasn't until later that night when I restored my phone that it fixed the problem. VERY weird. I talked to my friend and he said that he has gotten that No SIM error on and off ever since he got it. This happened on day 1, I hope it doesn't ever happen again, especially when I'm stuck on the side of the road with no computer to restore my phone in.

This common problem can be fixed easily using this method.

works for sim unlocking adapters and possibly for just plain sim cards by themselves also

try a peace of tap, it might be falling back from the sensor while in your phone
