I just switched from ATT to Verizon and also got a new iPhone 4s (traded in the 3Gs I had for 2 years). After I synced it at home to put all my apps, music, etc. back on it. It came up with a message on the phone's screen which said no SIM card was installed (or not found). The phone seems to be working fine. I thought it needed a SIM card to work? I really don't know what a SIM card is but I remember when I bought the first one 2 years ago hearing something about them. Can anyone tell me if I should be worried or what I can do to fix the issue? (I am going to call Verizon tomorrow but wanted ask the community as well).
