Yes, all other commands work ok.
I make GSM controllers many years...
(> elektronika.rs.ba)

Everything works fine... Siemens mobile phones and Siemens GSM module, even on sim300.

Call *101# is code for check prepaid account, and only this call don’t work with SIM900 modul (return ERROR).

The command syntax is:
ATD#;
Where "#" is the complete format of the number and, the ";" tells the MODEM that this is "Voice Call" not a "Data Call"

I tried this command many times on different phones and MODEMs.

Hope this helps.

BUT THIS IS VIOCE CALL!
Answer, of mobile operator is plain text (account and date of expiration of SIM card). Is it the same for most of the Countries?

Nooooo!!!!

This not VOICE - this CUSD.

Correctly call for SIM900:

AT+CUSD=1,"*111#" // for Kievstar - Ukraine // ( or AT+CUSD=1,"*101#" for UMC )
OK
+CUSD: 0,"Na rahunku: XXX.XXgrn; Xhvyl;Info pro bonusy na *112#,*118# i *119#. Zagubyv svoiu SIM? Vidnovy ii! Info:XXX*XX*",XX

or

ATD*111# // for Kievstar - Ukraine // ( or ATD*101# for UMC )
OK
+CUSD: 0,"Na rahunku: XXX.XXgrn; Xhvyl;Info pro bonusy na *112#,*118# i *119#. Zagubyv svoiu SIM? Vidnovy ii! Info:XXX*XX*",XX

Anyway that infernal continous ringing has stopped. Probably sorted out the other bugs too!

Thanks
