there is no respond after AT+CMGS in sim900

[nta_xyz]

hi.

I write this code for sending sms by sim900:

AT+CMGF=1;
AT+CSCS="GSM";
AT+CMGS="MY PHONE NUMBER";
//Write my SMS
SendCharToGPRS(0x1A);

after send 0x1A I receive the sms in my phone but I dont get any answer form sim900.
I think sim900 should send me "+CMGS:"LENGTH" but nothing happen .

could you please help me ?
