Data call over GSM is not working


#1
  1. When we dial out of WMP100:

atdphone#; - makes the voice call to the phone#
atdphone# - without ; does not make call and says NO CARRIER

  1. When dialing into the WMP100 from PC (or phone) WMP gives out:

CALL EVENT: 0 (ignored) - each time a ring occurs.

What could be the reason.

Is it possible that WMP100 is not configure to make Data GSM calls? If that
is the case how what configuration is required?

Thanks for any pointers.

What do you mean, “does not make call” ?

Does it attempt to call, but fail to connect, or does it not even attempt to call.

What clearing cause do you get?
(use AT+CEER)

If you enable WIND indications, what WIND events do you get?

What application are you using to give that?

I think it’s is more likely that your SIM is not correctly provisioned for Data calls - check with your service provider.
