Pk (Sim Puk); Cu (Cellular User Name); Cw (Cellular Password); Fc (Frequency Channel Number) - Digi XBee 3 Cellular LTE-M User Manual

AT commands
PK (SIM PUK)
Specifies the PUK for unlocking a SIM. This is needed only if the wrong PIN was used and the SIM is
locked out.
This command is write-only.
Parameter range
8 ASCII digits or space character
A value of a single space character (ASCII 0x20) acts as an empty value.
Default
0x20: A single ASCII space that indicates there is no PUK.

CU (Cellular user name)

Specifies the user name used when authenticating to the cellular network.
This command is write-only.
Parameter range

Default
0x20: A single ASCII space that indicates there is no cellular password.
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.
