Statistics
The Statistics tab contains these details:
- Band — The frequency band in use.
- Signal Type — The type of cellular connection, such as 4G or 5G.
- Reference Signal Received Power (RSRP) — Indicates the received signal power in decibels per milliwatt (dBm).
- Reference Signal Received Quality (RSRQ) — Indicates the ratio of the received signal power (RSRP) to all levels of signals on the same frequency in decibels (dB). A higher RSRQ value indicates a better signal to noise ratio.
SIM Card Lock PIN
Some cellular providers lock their SIM card with a PIN to prevent unauthorized use. If the SIM card is locked, you can specify the PIN to unlock the SIM card.
If you do not know your PIN, contact your provider for information on how to disable or unlock the SIM card. Do not attempt to guess the PIN because too many incorrect entries can lock and disable the SIM card.
After you specify a correct PIN, the Firebox unlocks the SIM card and disables the PIN permanently. The PIN is not required again even if the Firebox is rebooted or restored to factory default settings because the action is performed on the SIM card.
The Unlock SIM Card option only appears when the Firebox detects a locked SIM card. This option is only available in Fireware Web UI and Firebox System Manager.
