For details, refer to the prompts in the table to find the protocol. <alpha> character information corresponding to the address in the phone book of the simplified type. For the format, see + CSCS.
The length of the information body <data>. When the PDU mode (+ CMGF = 0) is used, it indicates the number of TPDU bytes.
