SIMDTC
The module provides the regulated supply voltage for the SIM-card and the circuitry to detect the insertion
or extraction of the SIM-Card in or from the mobile.
The SIMDTC is disabled by default (see AT$SIMDTC in the EIII AT Command Manual for settings).
When enabled, the SIMDTC pin has an internal pull up to Vcc and can be configured to detect a SIM
insertion when the SIMDTC is either pulled to ground or left floating.
It can configured to detect either just a SIM removal or both removal and insertion.
When the module detects a SIM removal, it will de-register from the network. When the module is
configured to and detects a SIM insertion, it will reset the module and re-register on the network.
The SIM-card presence detection logic is active even when the system is in idle model.
