Is the "orange" APN the one you would have expected to be connected?

We can see how there is TX traffic (bytes tx > 0) but there is no RX
traffic (bytes rx == 0, the field is not shown).

The DNS configured by the network, 192.168.10.110 is a bit weird given
the address you got, but that doesn't mean anything really. Can you
try to "ping" that DNS address?

Can you install dnsutils in mobian and run these? (assuming you still
have that same DNS server address):
dig @8.8.8.8 modemmanager.org
dig @192.168.10.110 modemmanager.org

What's the output of "ip route"? Do you have a default route set in
the WWAN connection?
