The SIM908 GPS/GPRS module I'm developing with is having problems registering with my local towers.
I can plug in it and communicate with the UART just fine. It doesn't seem to be a power issue as the module doens't power off or report low voltage. There is a GSM antenna attached, and the signal appears to be good. The NET LED is flashing for a fraction of a second, every second or so.
Here is the output of CREG, COPS, CSQ and CENG:
What I find interesting is COPS is reporting the "Rogers" network (MCN 720), while the Engineering report only references a Telus network (MCN 220)
The simcard I have should work on the Telus network.
Any thoughts?
