My G3 was notifying me that there is No SIM found. At one point it said the SIM was not readable. I went through the troubleshooting steps and the problem remained. Once again, I went through this with the VzW representative over the phone. I took it to a VzW store and they replaced the SIM. After 24 hours I now have the same problem. I'm wondering if it is the phone and if there is a solution that anyone may know of.
