This is interesting. Some of the owners of the Apple iPhone 4S are reporting that their devices are giving them a strange error ‘No SIM card installed’.
The problem is limited to a very small number of owners but is affecting the users on all the three networks AT&T, Sprint and Verizon.
Apple has not made any statement yet. It is not clear if it is a software problem or a hardware glitch.
Apple iPhone 4 famously suffered from the bad reception problem if the device was held in a particular position. This is the first issue being reported about the iPhone 4S edition.
