This TS specifies the structure of the Secured Packets in a general format and in implementations using Short Message Service Point to Point (SMS-PP) and Short Message Service Cell Broadcast (SMS-CB).

Furthermore, the coding is specified for a set of common application commands within the secured packets. This set is a subset of commands specified in TS 11.11 and allows remote management of files on the Subscriber Identity Module (SIM) in conjunction with SMS and the SIM Data Download feature of TS 11.14.

For SIM cards based on TS 03.19, the set of commands used in the remote applet management is defined in this TS. This is based on the Open Platform card management specification. For SIM cards based on other technologies, other loading mechanisms may be used.

This TS is applicable to the exchange of secured packets between an entity in a GSM PLMN and an entity in the SIM.

Secured Packets contain application messages to which certain mechanisms according to TS 02.48 have been applied. Application messages are commands or data exchanged between an application resident in or behind the GSM PLMN and on the SIM. The Sending/Receiving Entity in the GSM PLMN and the SIM are responsible for applying the security mechanisms to the application messages and thus turning them into Secured Packets.
