Difficulty enabling modems

[Marc Murphy]

Thanks Alex, I will have to check the sim connection to the modem as there is definitely a sim in there and it's enabled if I stick it in the phone. 

It's on a development embedded platform so there are some teething problems at the moment. 

I'll get the iron and scope out.
