GSM AT Command for issuing service command

[traxonja]

Hello,

Is there an AT command for dialing /issuing gsm service commands?

For example, when you dial on your phone's keypad: *43# and press YES you would see "Requesting..." or something like that. That's cool.

The question is, how to do that by using AT commands?

I have tried:

ATD*43#
ATD*43#;

The result is the same, it never "dials" as "service" command but tries to establish plain data or voice call.

I don't need it for call waiting, I need this for refilling my prepaid account. The command I will need to issue is:

*124*PREPAID_NUMBER#



Thanks!
