Many iPhone users claim that the latest iPhone 4S smartphone from Apple has new problems.
Although the battery autonomy problems were not solved even after a update was released, now United States iPhone 4S users claim that they have big problems with the functionality of the AT&T network. Precisely, they are experiencing SIM activation problems on their iPhone 4S phones.
Those who reported the problems say that the phone displays messages like Sim Card failure or Bad Sim Messages, after using Siri.
What is weird is that the error messages are not only experienced by clients who use iPhone 4S on the GSM network ( AT&T ) but alos by those who own phones connected in the CDMA network ( Verizon ).
For the moment it is unknown what causes this problem ( mobile operators, iPhone 4S smartphone or the iOS 5 operating system ) but it seems that in most cases a iPhone 4S reboot solved the problem.
Even if the problem has such an easy fix, we have to note another iPhone 4S problem.
