Difficulty: MediumMobile Device Wireless and Network Connectivity

A help desk technician is setting up a newly unboxed cellular tablet for a remote employee. After inserting a provisioned corporate SIM card into the device, the tablet shows a 'No Service' status indicator and cannot establish a cellular data connection. The cellular carrier indicates that the physical mobile device hardware itself must be whitelisted on the corporate account profile using its unique 15-digit international hardware serial number. Which of the following identifiers should the technician locate on the tablet and provide to the carrier?

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

Answer

The technician must locate and provide the International Mobile Equipment Identity (IMEI) to the cellular carrier.
The International Mobile Equipment Identity (IMEI) is a unique 15-digit hardware identification code embedded in mobile radios. Cellular network providers use the IMEI to identify, authorize, or block specific physical mobile devices on their networks.

Step-by-Step Solution

1
Identify the carrier's provisioning requirement
The carrier requires the unique 15-digit physical hardware serial number of the mobile device.
Whitelisting a physical mobile phone or tablet on a carrier network requires registering its unique hardware radio identifier.
2
Differentiate between device hardware identifiers and subscriber SIM identifiers
The International Mobile Equipment Identity (IMEI) represents the physical device, while the International Mobile Subscriber Identity (IMSI) represents the SIM card and subscriber account.
Providing the IMEI registers the tablet hardware, whereas the IMSI was already associated with the inserted SIM card.

Key Concept

Mobile device cellular network identification using IMEI versus IMSI.
