A user reports that their smartphone is experiencing intermittent connectivity issues, specifically with the cellular network. The user has confirmed that other devices on the same network provider are working correctly in the same location. Which physical component of the smartphone is MOST likely causing this issue?
- ANFC chip
- BCellular antenna
- CBluetooth module
- DGPS antenna
Show answer & explanationAnswer & explanation
Correct answer: B. Cellular antenna
If cellular connectivity is the only issue and other devices work fine, it points to a problem with the specific phone's cellular hardware. The cellular antenna is the primary physical component responsible for sending and receiving cellular signals.
Why the other options are wrong
- A. A faulty NFC chip would affect tap-to-pay or short-range communication, not cellular network connectivity.
- C. A faulty Bluetooth module would affect short-range wireless connections (headphones, etc.), not cellular network connectivity.
- D. A faulty GPS antenna would affect location services, not cellular network connectivity.
