Defined Values
<spn_type>:
0: GSM_SPN
1: UMTS_SPN
<disp_rplmn>:
0: Do not display RPLMN
1: Display RPLMN
99: This field is invalid, and it is not necessary to read the spn_name field any longer.
<coding>: coding scheme. It means the character code of the spn_name field, and
specifies the language.
0: GSM 7 bit Default Alphabet
1: UCS2 (namely, upload the spn_name in the format of original data).
<spn_name>: a string. In case of GSM7bit code, the string is composed of 16
characters at most. When the coding scheme is 1, and the contents of the string are
data described by “hexadecimal text value”, the string will not be greater than 32.
When the coding mode reported on the board is “UCS2”, this parameter should be
completed as a hexadecimal numeral with 0x removed.

Examples
For example: When the 7 bit coding format of SPN is read as "China Mobile", the
following will be fed back after the read result is reported: ^SPN:0,0, China Mobile; if it
is "China Mobile" in the USC2 coding format, the following will be fed back: ^SPN:1,1,
"804E2D56FD79FB52A8".
