Galaxy nexus No Signal

[mertbba]

I just bought Galaxy Nexus from Play Store couple days ago. I inserted my Straight Talk Micro Sim and the phone saw it. It was working perfectly. After charging my phone at night, in the morning there was no signal on my phone. I tried reinserting the sim card, airplane mode, other sim cards. Even when no sim card is installed, the phone doesn't say "No sim card installed", it just stays as there is no signal. When I search for networks, I get a "Error while searching for networks" message.

What should I do? Thanks.

It might be defective, but, you could try "Factory data reset" under Settings> Backup & Restore.
