CDMA cat! @ #￥ #% (*, Only text messages can be sent if the PDU is not supported. In addition, the Chinese text message is UNICODE and cannot be input in the Super Terminal. Only programs can be written.
This problem is often discussed on the Internet, and sometimes garbled. Post the successful code of C.
Reprinted please indicate the source

// Chinese CDMA Transmission, UNICODE encoded bytes
Byte [] B = Encoding. BigEndianUnicode. GetBytes (content );
// You cannot add 86 to the phone number of the AT command of CDMA. Otherwise, although the message is successfully sent, the SMS center responds to error code 5.
