Whenever I restart or power off & on my HTC one V, next moment I see a cross mark on the network service i.e. SIM shows offline and on screen only message shows "no SIM found, Emergency calls only". Frustrating part is there is no option to make the SIM online or switch to the network operator manually. my phone is not even a month old. I have already given it for a s/w update when it showed a number of problems after buying and expected this problem will also fix. This time, after a software update, I restarted the phone. And since then, the SIM has gone offline. This is so disappointing. . Please help.
