(Pg 7):

MNOs' UICC architecture has it's limitations. Imo MNOs will use the TEE to deploy services and apps for which the UICC is not suited.

Mobile Network Operators: MNOs are considered reliable partners for service deployments on smartphones. The use of a UICC (usually owned and managed by the MNO) is relevant to deploy some services, but for some applications that exceed the resource capabilities of the UICC, there is a need to have a higher level of security than what the Rich OS offers. The Advanced Trusted Environment: OMTP TR1 specification1 provides a mechanism to satisfy this requirement by delivering a comprehensive security roadmap aligned with current threats, business opportunities, and the overall industry
objectives of achieving hardware-backed security.


Again, MNOs as service providers can deploy their app products in the TEE including a TPM MOBILE running in the TEE, apps the UICC can't properly host.

OS and Application Developers: A well-defined and standardized TEE allows defragmentation and creates broader alignment in the industry around commonly deployed security frameworks and associated software and APIs. This allows for a large ecosystem of application vendors in numerous segments and industries, which ultimately leads to greater economies of scale.


TCG and Global Platform are converging, in fact Microsoft Phone 8 has already deployed a TPM in TrustZone TEE in conformance with the TCG/GP standards.

In 2012, GlobalPlatform and the Trusted Computing Group (TCG) created a joint work group to enable the sharing of expertise and collaboration around mobile device industry standards. This white paper, the first joint work item, introduces how GlobalPlatform's defined TEE standards and TCG Mobile Trusted Module (TPM MOBILE) can work together in mobile devices to provide security, peace of mind and enhanced services to users.
