Problems with the Cellular radio

Nov 9, 2012 at 1:27 PM

I recently bought the cellular radio by seeed studio, at first it was working perfectly, it sent and recieved messages without any problem but it suddenly stopped working. I didn´t change anything  and the modem initialized fine, but that´s all it does.  I used the reset button and reinstalled the driver but it still doesn´t work.Does someone has any suggestions about what could had happened?Thanks
