A mobility technician is training a junior technician on mobile network connectivity components and device identifiers. Match each mobile connectivity term on the left to its correct technical description on the right.
- IMEIA unique 15-digit hardware serial number used to identify a specific physical mobile device on a cellular network.
- IMSIA unique identifier tied directly to the SIM card used to identify and authenticate a subscriber on a cellular network.
- Baseband UpdateA firmware update for the mobile device's radio interface layer that controls cellular communication and modem functionality.
- APNThe configured network settings that determine the gateway path and IP routing for mobile cellular data connections.
Answer
IMEI matches the unique 15-digit physical device serial number; IMSI matches the unique subscriber identifier tied to the SIM card; Baseband Update matches the radio interface firmware update controlling cellular communications; APN matches the network configuration defining the cellular data gateway routing.
Each cellular connectivity term correctly aligns with its distinct operational level: IMEI identifies physical hardware, IMSI identifies the SIM card user/subscriber, Baseband updates update modem radio firmware, and APN settings direct data traffic through the correct carrier gateway.
