How to make ZTE MF823D modem work in Bananian?

Question

Debian

There is a Bananian latest build. And the new ZTE MF823D modem from Beeline
When connected to a Banana (BananaPi), it is correctly recognized as a usb0 interface.
Next, I raise dhcpcd usb0 - an IP is assigned to it and everything seems to be fine, but there is no Internet at all.
Even Google does not respond:

[email protected] ~ # ping -I usb0 8.8.8.8 
PING 8.8.8.8 (8.8.8.8) from 192.168.0.182 usb0: 56(84) bytes of data.
From 192.168.0.182 icmp_seq=1 Destination Host Unreachable
From 192.168.0.182 icmp_seq=2 Destination Host Unreachable
From 192.168.0.182 icmp_seq=3 Destination Host Unreachable

Although everything is OK with the local

[email protected] ~ # ping -I eth0 8.8.8.8                                                                                                                    :(

auto eth0

I think that the cant is in the network settings, but the skill is not enough to deal with it.
PS: Everything connects and works correctly on my laptop, there is Internet. If you send a CGI command from the device to activate the network, then in response it writes an error:
