I need fast help on this.
I bought an iphone 4s recently and the problem about my iphone is that it gets full range but still most of the times i can't receive a call from anyone nor i can make a call to anyone. To make my phone i available on the network i have to turn airplane mode on and off several times, or reset the network settings, or reboot the iphone 4s.
After like 4 hours or so without using the phone it says invalid sim. But when i reset the network settings again the sim is available.
Got any idea on what is happening to my phone?? This is the first time something like this is happening to an iphone that i bought. Please give me some quick help on this.
