I am developing an hardware which uses wavecom Q24 series module to send data from remote location to server.
Now the problem is I am unable to established (CSD) data call.
For testing purpose I am using two sony ericsson(w550) mobile having SIM cards with data number facility on each and connected via hyperterminal to two different PC. I then dialed the data number using AT command ( ATD). But response is “No carrier”. I am using proper AT command on both side.
The SIM provider said data number is activated.
So my question is where I am doing wrong?
Can I make (CSD) data call between two mobile?
Is there any settings required on mobile to established data call?
Your help will be appreciated.
