Question: In a scenario where a Mobile Equipment (ME) initiates an emergency call without a Universal Subscriber Identity Module (USIM), and the Emergency Call Code (EFECC) file contains no valid number, what does the ME rely on to set up the emergency call?
Option 1: The ME uses the last dialed number from its call log.
Option 2: The ME prompts the user to manually enter an emergency number.
Option 3: The ME defaults to a standard, internationally recognized emergency number (e.g., 112 or 911) hardcoded into the device’s firmware.
Option 4: The ME uses the emergency numbers it stores internally for such scenarios.
Explanation: According to the specified behavior for handling emergency calls without a USIM, if the EFECC does not contain any valid number, the ME is designed to utilize its internally stored emergency numbers. This ensures that emergency services can still be reached even in the absence of a USIM, relying on pre-configured numbers within the device itself.
