Using GSM library: how to select mobile network

Hi all,

I am using the GSM library for sending SMS text messages. How can I select the mobile network to connect to? I have entered my PIN, but the network is not selected.

I've never used one, but my understanding was it's a matter of which network you got a sim for.... Just like when you stick your sim in a phone handset? Or is that too simplistic an approach?

Thanks for the reply. It is correct which kind of SIM you have received. But for testing purposes, I need to connect to a different network (such as roaming etc).

Any clue if there is somekind of function available to select an appropriate network?

any update from someone? :-)

What library? Have you investigated the library documentation and source code?
