Contents:

This data item commences with the TS‑Service‑Centre‑Address as specified in TS 24.011 [10]. The bytes immediately following the TS‑Service‑Centre‑Address contain an appropriate short message TPDU as specified in TS 23.040 [6], with identical coding and ordering of parameters.

Coding:

according to TS 23.040 [6] and TS 24.011 [10]. Any TP‑message reference contained in an UE originated message stored in the USIM, shall have a value as follows:

Value of the TP‑message‑reference:

message to be sent: ‘FF’.

Message sent to the network: the value of TP‑Message‑Reference used in the
message sent to the network.

Any bytes in the record following the TPDU shall be filled with ‘FF’.

It is possible for a TS‑Service‑Centre‑Address of maximum permitted length, e.g. containing more than 18 address digits, to be associated with a maximum length TPDU such that their combined length is 176 bytes. In this case the ME shall store in the USIM the TS‑Service‑Centre‑Address and the TPDU in bytes 2 to 176 without modification, except for the last byte of the TPDU, which shall not be stored.
