Great. In addition, you might want to try and attach something to the diagnostics port. You should be able to read through the port any AT commands, to make sure it's working correctly. 

I believe there's a list somewhere of the messages you'll get from the diagnostic port for that chip.. 901 is it?  (I can't remember, but it's what we used to diagnose the SIM card was at fault.)

Nikki. 

P.S. What SIM are you using? Global? O2?

All the v2 modules are supposed to be machine soldered, and we have had almost zero returns of broken modules.I would be grateful if you could let me know the serial number of your module, the approximate date you received it, and if possible a picture of the soldering issues.
