A smartphone user inserts a new SIM card provided by their cellular carrier. To activate data services, the network operator requests the unique identifier assigned specifically to the subscriber account on the SIM card. Which identifier should be provided?

  1. IMSI (International Mobile Subscriber Identity)Answer
  2. B
    IMEI (International Mobile Equipment Identity)
  3. C
    APIPA (Automatic Private IP Addressing)
  4. D
    POP3 (Post Office Protocol 3)

Answer

IMSI (International Mobile Subscriber Identity)
IMSI (International Mobile Subscriber Identity) is the unique string of numbers assigned to a SIM card to identify and authenticate the subscriber on a cellular network.

Step-by-Step Solution

1
Identify the cellular network provisioning requirement
The carrier needs the specific identification number associated with the SIM card subscriber account.
Cellular carriers use subscriber identifiers stored on SIM cards to authenticate access and link devices to specific service plans.
2
Differentiate between mobile hardware and subscriber identification terms
IMSI (International Mobile Subscriber Identity) uniquely identifies the user's cellular subscription on the SIM card, while IMEI identifies the physical device hardware.
Providing the IMSI satisfies the request for SIM-based subscriber provisioning.
