“*” means this function is under development.
3.10. USIM Card Interface
The module contains one USIM interface to allow the module to access to the USIM cards.
3.10.1. USIM Card Application
The USIM interface supports the functionality of the 3GPP specification, which is intended for use with a
USIM application Tool-kit.
The USIM interface is powered by an internal regulator in the module. Only 3.0V USIM cards are
supported.
