wavecom 2687 cann't send sms in application!
Hi to all

I have a very weird problem: I can send sms in shell ,by AT+CMGS.And i receive sms in application,but i cann't send my sms in application!
there are two method i used in my application.
1、call adl_smsSubscribe，then adl_smsSend，but in my ctrl_Handler,it print : ADL_SMS_EVENT_SENDING_ERROR

2、adl_atCmdCreate("AT+CMGS=\"+86159xxxxxxxx\"",false,SendSMS,"",NULL);

  bool SendSMS(adl_atResponse_t *paras)
{
  if(adl_atCmdSendText(paras->Dest,"test thanks!!!\x1A"))
{
TRACE((1,"send sms ok"));
}
else
TRACE((1,"send sms ERROR"));
}

it says that the Dest isn't aviliable!

I think it isn't the code's problem,is there any configuration in my hardware?thanks a lot!
