memset( &SmsMsg, 0, sizeof(SmsMsg) );
SmsMsg.cbSize = sizeof( SmsMsg );
SmsMsg.dwParams = SIM_PARAM_MSG_ALL;
wcscpy( (SmsMsg.lpszAddress), TEXT("+8613812345678") );
SmsMsg.dwAddressType = SIM_ADDRTYPE_INTERNATIONAL;
SmsMsg.dwNumPlan = SIM_NUMPLAN_NATIONAL;
//GetSystemTime( &(SmsMsg.stReceiveTime) );
SmsGetTime( &(SmsMsg.stReceiveTime), &dwTmp );
SmsMsg.cbHdrLength = 0;
//strcpy( (char*)(SmsMsg.rgbHeader), "" );
wcscpy( (SmsMsg.lpszMessage), TEXT("Received sms message.") );

Yes, I have tried it. I found I set dwNumPlan = SIM_NUMPLAN_TELEPHONE; maybe you can try it.

Hi,

Since you don't use SmsMsg.rgbHeader, I think you should set SmsMsg.dwParams = SIM_PARAM_MSG_ALL & ~SIM_PARAM_MSG_HEADER;

Thanks

you should call SimInitialize at first and call CloseHandle in the end.

Thank you,

But, I have tried it, Fail too.

SIM_PARAM_MSG_ALL & ~(DWORD)SIM_PARAM_MSG_HEADER;// & ~(DWORD)SIM_PARAM_MSG_HEADER_LENGTH;

Did you test your method

I've sent it to you. Because it's a privileged API, make sure you have provisioned your device with privilege and signed the code. Hope it will help.
