Zorluk: OrtaMobile Device Wireless and Network Connectivity

A field service technician is provisioning a cellular-enabled tablet for a remote employee. Although the SIM card is physically inserted, the tablet fails to register subscriber data services. The cellular carrier reports that the technician provided the 15-digit unique serial number tied to the tablet's physical wireless hardware modem instead of the account subscriber identifier. Which identifier was mistakenly submitted to the carrier?

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

Cevap

The IMEI (International Mobile Equipment Identity) was mistakenly submitted because it identifies the physical mobile hardware device rather than the SIM card subscriber profile.
The correct answer is IMEI (International Mobile Equipment Identity). The IMEI is a 15-digit global hardware identifier permanently assigned to the physical mobile device and its cellular radio interface. Submitting the IMEI identifies the physical device model and serial status, but does not provide the subscriber authentication credentials linked to the SIM card.

Adım Adım Çözüm

1
Analyze the scenario requirements
The technician submitted a 15-digit hardware serial number assigned to the physical mobile modem.
Differentiating between hardware identifiers and subscriber profile identifiers is critical during cellular provisioning.
2
Identify cellular hardware vs. subscriber identifiers
IMEI represents the physical equipment modem, while IMSI represents the subscriber account on the SIM card.
Providing the IMEI to activate subscriber services fails because the network authenticates subscriptions via the IMSI/SIM profile.
