Hi, I have a big problem because I was sending SMS using NCLMsg.dll and visual basic and everything was working fine. But now I bought the 3120 and tried using the same application but it doesn´t work.

It say the phone is connected and everything looks fine, but it always says message send fail.

Why could this be? Does the 3120 have any restrictions the 3100 doesn´t have?

Maybe some security?

Any help is appreciated, I need it for my work.
