The modem is being assigned an IP address by the network operator, and there is some data being sent.
But when testing with a loramote, all information is sent via the ethernet conection instead.
Bearer priorities are set to "ppp0, eth0, eth1".
Checking the log, I find this:

daemon.warn pppd[1214]: Could not determine remote IP address: defaulting to 10.64.64.64
