When the data connection is started with AT^SWWAN, the modem expects the DHCP discover packet from the TE while the command is running, i.e. while the modem has not replied yet. In order to achieve that, the bearer is marked as connected as soon as the command is issued. This makes the NetworkManager start the DHCP process. If the modem replies with an error, the bearer will be marked disconnected later on. See https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/50 for a similar functionality in the ublox driver.
