wwan0 (cellular data) ip configuration is POINTTOPOINT not BROADCAST
Carrier: ATT prepaid (US)

I use Settings -> Mobile Network screen and slide the switch icon to on. Makes a connection to my carrier but no Internet access (I can ping att.com but that's it).

ip link show wwan0
4: wwan0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1430 qdisc pfifo_fast state UNKNOWN qlen 1000

"POINTTOPOINT" makes me think of a PPP connection; compare to my Wifi settings:

ip link show wlan0
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether 02:ba:93:10:c9:af brd ff:ff:ff:ff:ff:ff

Is there a command (like an option to ip) that I can configure wwan0 as BROADCAST? Where in the NetworkManager startup sequence, or elsewhere in the postmarketOS networking configuration, would I be able to find/change the settings for wwan0?

Surely I'm not expected to make a PPP connection?
