Nokia 6300 Dual-Sim RM217 Problem I went abroad and purchased a Nokia 6300 Dual-Sim mobile phone, it was working perfectly fine over there, I just came back from my holiday and now it doesn't read any Sim Card, the message pops up 'Invaild Sim' and sometimes 'Emergency Calls Only'. I have tried many Sim Cards but same result over again, I even went to some local mobile phone shops but they were left scratching their heads. |
