I started getting the SIM Failure Message 3 days ago. I removed and reseated the SIM and am still receiving the message. I called Sprint and they transferred me to their international division. The person on the other end of the phone that I ended up with didn't have a clue as she was clearly reading from a script. I asked her if she could just send me another SIM and she told me that she couldn't and that I would have to go to a Sprint store and have them examine the phone. She didn't mention that I could go to an Apple store also. Is replacing the SIM the normal course of action here? In 12 years I have never had a phone do this. Any thoughts?
