FC (Frequency Channel Number)

Returns the EARFCN of the current cellular connection.

The EARFCN encodes the carrier frequency or frequencies that the cellular radio is using. Refer to the 3GPP specifications or various online tools or guides to determine the corresponding band number.

If the value cannot be retrieved for some reason, such as the device is not on the network, the response is empty. When in command mode and the value cannot be retrieved, OK is returned.
