Have you tried to remove and reinsert it again ?
If you already have done that.. Try soft reset
If it's still same . Hard reset is recommended

Same thing happened here... I tried the Technical Preview 2 days back and problems began to show up after a day. Phone was not detecting SIM card and I reinserted the SIM a number of times, a notification came saying "your flight mode is turned on, please turn it off", but when I checked the setting, I could see nothing under the flight mode section (there was no option to turn on or off). I then restarted the phone 2 times and the phone went black and nothing was working. I borrowed my friends PC (as mine was running on Windows XP and the recovery tool does not support XP) and installed recovery tool and it took me about a day to go back to Windows Phone 8.1. I lost a lot of data from my phone due to this incident. So, if your phone is still alive, please back up all the things before it stop working...
