Can Connect to 3G Modem via GSMComm but cannot see any SMS

Question

Hi,

I'm trying to write an application that receives SMS messages into the app I'm developing (in C# if you care :). Research indicates the best bet is to use GSMComm library.

I've downloaded the library and using the demo app I have managed to connect to the 3g modem (a Huawei E1756) but when I query it for SMS's received it comes back with 0.

Interestingly if I use the software that comes with the application then I can see the messages.

Anyone got any clues on why this would be? Or other tips on how to retrieve the messages?

Cheers, Kym

Depending on how the modem is setup, messages can be stored on either the SIM card or in phone memory.

I would check that the demo app is looking in both places for old messages.
