My iPad Air randomly displayed the, " No SIM installed" message and invalid SIM up where the signal strength normally is. I tried resetting the iPad and reset the network settings with no success. Before taking it into the Apple Store, I want to see if it is the SIM card that went bust or something is wrong with the iPad Air. I want to simply take the SIM from my iPhone 5 and put it into the iPad Air( both Verizon models) just to see if the iPad Air will recognize the card and it will go right back into the iPhone. Will that mess anything up with either device?
