Yers sir it a sim
SOURCE: will not read smartchip
I had the same problem but i fixed it. I'm not sure if this will work for you though. I took off the battery door and noticed that although my battery fit, it was somehow off by a few millimeters maybe. I took a tiny piece of paper, folded it and then fit it near the edge of the battery. This pushed the battery exactly where it should've been and then the phone could read the sim card again. I don't know how it got knocked outta wack but this seemed to help.
SOURCE: my lg shine says that it needs a smartchip but its
Turn off the phone. Take the battery and Sim Card out. Make sure there is no dust or dirt of where the Sim Card goes. Blow air (from your mouth) of where the Sim Card goes. Sometimes rubbing a soft pencil eraser on the Sim Card contact points can help. Then place the Sim Card back in the phone. Make sure it is in the right position; copper contacts facing downward. Put the battery back in your phone. Turn it on, and see if the smartchip rejected goes away.
If not you may need to contact your Phone Provider’s Tech Support to troubleshoot and confirm that you may need a PUK reset code to register or you may need a new Sim Card, as they do fail from time to time.
