Class 2, for use of SIM only. After storing it,
the storage state is returned to the SC.

Class 3, stored to the TE. When the MS
receives the message, but has not
transmitted it to the TE, it will give a response
to the SC.
<TP-UDL>: number of bytes occ
upied by the “user data” domain. If the value is 0, the
“User data” domain does not exist.
<TP-UD>: t
he “user data” domain may include “user data header”. If it includes the
header (namely, the value of bit6 in byte0 is 1), the value of TP-UDL is equal to the
length filled in the “User-Data-Header” plus the length of “User-Data”. The value of
TP-UDL depends on the specific coding mode. If it is a 7-bit default code, it indicates
that there are a total of how many septets; if it is a 8-bit code, it indicates there are a
total of how many Octets; if it is a UCS2 code, the TP-UDL still means a total of how
many Octets; if there are compressed 7-bit or 8bit or UCS2 codes, the TP-UDL
indicates there are a total of how many Octets after compression. The specific
representation structure in the “User data” domain is shown in the following diagram:
