Question: I have read the answers send by drelectro, which are very detailes. Althiugh I need more specif programming tips.

I am trying to satrt the GM29 by using my personal SIMM card, first is this possible?

Second can I use this card and the modem to conect to a RS232 PLC port and use thois modem as an standard data modem? Which stpes do I need to consider?

Third is there a way to know if I am really looking at the modem ones I had conected it to the computer an setting it as a Standard 19200 modem?

Did you try to use a ISDN modem or better a call from one GM29 to other GM29?
By GSM to GSM call you can be nearly 100% to get the bearer data, but may no bearer data if the base station does not send any bearer code. Please make a GSM to GSM call and tell the result.
