Tap on “Cellular status” in order to display the current status of the network communication. Check the
value of the “Registration status” field.
If the value is:
● REGISTERED
● REGISTERED ROAMING
The sensor has registered on the network. You do not
need to change the network settings of the device.
If the value is:
● NOT REGISTERED, SEARCHING
The sensor is still trying to connect to the NB-IoT
network. Wait for 5 minutes and check the status
again. It may also be required to manually select the
network, on which the device has to register (this is
described in the further steps of this manual)
If the value is:
● REGISTRATION DENIED
● REGISTERED EMERGENCY ONLY
● UNKNOWN
The device is not able to properly register on the
network. Contact your mobile operator to identify and
solve the issues. If the device has been rejected by
the network, the reason will be listed in the
“Registration reject cause”. Provide your operator with
that value, to speed up the troubleshooting.
If the value is:
● NOT REGISTERED_NOT_SEARCHING
Most probably there is no NB-IoT network coverage in
the place where the sensor is located.
If the device has not registered on the network automatically, you need to manually select the carrier.
Connect to the sensor with Efento Logger, go to the “Settings” menu and select “Network settings” ->
“PLMN code”. PLMN is an unique operator identifier. You should get the information about the PLMN
code of your operator either from the operator or you can check it
. Set the PLMN code, save
changes and after a few minutes check, if the sensor has successfully managed to register on the
network.
In order to allow the sensor to communicate with the server, you need to assign it to a proper APN. The
APN (Access Point Name) is the name of a gateway between a mobile network and the public Internet.
