SIM900 can't execute command: ATD*101#;

What is solution ?
 

can you execute all other basic commands.... and is 101 a valid number in your country

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).
 

Update firmware SIM900 to 7 version.
And no use ;
ATD*101#

; used voice call only
 

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?

Where I can find flash software and flash file ?
 

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

After reset module add command at+cusd=1\r" // ---->Enable unstructer service
 

Hello,

tried
at+cusd=1\r" //
error

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

2.45 am going to bed

Thanks

Ally
