No such luck: (sorry for the wrap)

As you mentioned, there's probably some logic missing here in OpenWrt. I'm
guessing the only recovery here is to restart ModemManager.
Here's some more debug if it helps:
root@AWC-EI:~# mmcli --modem 1 --bearer=1
------------------------------------
General | path: /org/freedesktop/ModemManager1/Bearer/1
| type: default
------------------------------------
Status | connected: yes
| suspended: no
| interface: wwan0
| ip timeout: 20
------------------------------------
Properties | apn: firstnet-broadband
| roaming: allowed
| ip type: ipv4v6
------------------------------------
IPv4 configuration | method: static
| address: 10.55.89.75
| prefix: 29
| gateway: 10.55.89.76
| dns: 107.112.229.135
| mtu: 1430
Earlier, when it was running:
Wed Jul 14 11:50:45 2021 daemon.notice netifd: wwan (6178): modem available at
/org/freedesktop/ModemManager1/Modem/0
Which looks like the modem here moved from 0 to 1 (I don't know how the number
allocation happens)
After restart of ModemManager and then ifup wwan, reconnection is successful.
