GSM AT Command for issuing service command

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!

AT+CCWA Call Waiting
3GPP TS 27.007, Section 7.12 /2/. Controls call waiting supplementary service and presentation of +CCWA unsolicited result code. When the status request response from the network indicates that SS is active for specific data bearer services (for example, ‘circuit async’), the AT interface shall only indicate ‘data’ (<class>=2) (‘not active’ case is displayed only when SS is not active for any service; that is, +CCWA: 0,7). Supported <class> values are 1, 2, 4, 5, and 7.

Is the AT command set for siemens is the same as that of NOkia or are there some difference?

Well, 80% AT commands are the same. The rest is phone-based AT commands which are not the same. Here is a pdf document in attachment - AT commands for siemens and AT+CUSD is not listed
