1111 Data coding/message class
<VP>: Indicates the validity period, which starts from the message being received by
the SC. If VPF=00, this field is lacking. The duration is expressed as follows:
VP value
0 to 143
144 to 167
168 to 196
197 to 255
<UDL>: Length of user data. The value of UDL depends on the specific coding mode.
In case of default 7-bit coding, it indicates there are a total of how many septets.
In case of 8bit coding, it indicates there are a total of how many Octets.
In case of UCS2 coding, UDL indicates there are a total of how many Octets.
In case of compressed 7-bit or 8bit or UCS2 coding, UDL indicates there are a total of
how many Octets after compression.
For the compressed message codes, the data length of <UD> should not be more
than 160septets; for the message of uncompressed codes, the <UD> length should
not be more than 140Octets.
<UD>: User data. The data validity depends on the parameter UDL.

Bit2 Reserved. The value is 0.
Bit2 Coding mode of message. The values are as
follows:
0: GSM 7 bit default code
1: 8bit data
Bit1 bit0 message type indication
0 0 : Class 0, providing display and reply to the SC
that the message is received but not stored.
0 1 : Class 1, stored to the NV (or SIM card if the
NV is full)
1 0 : Class 2, for use of SIM only. After the
message is stored, the storage state will be replied to the
SC. If the SIM card is full, the SC failure and the reasons
will be reported.
1 1 : 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.
