I just bought a Verizon prepaid phone from Walmart, and I can't get it to activate. Customer service did not help at all, and they didn't know what was wrong. An error keeps happening when I try to register the sim, it says "Sim not recognized or registered." The phone wont activate either online, by phone, or call code. I have called customer service 5 times, and the keep hanging up on me and can't fix the problem. Does anyone know of anything that would help?!
