Problem - connection is not working. I use these commands (discovered by sniffing original firmware):
(SIM is pinless, APN is internet - Polish ISP Play)
AT+ZGDCONT=5,"IP","internet",0
AT+ZGPCOAUTH=5,"","",0
AT+ZGACT=1,5
In terminal:
OK
AT+CFUN=1

Thanks for using picocom
Now, I can use dhcp on interface usb0:
root@OpenWrt:~# ifconfig usb0 up
root@OpenWrt:~# udhcpc -i usb0
udhcpc: started, v1.33.2
udhcpc: sending discover
udhcpc: sending select for 10.155.212.195

It looks similar to Mikrotik R11e-LTE6. But there's no transmission, you can only ping the gateway, nothing else.

Do you have experience with a similar modem? What else can be done?
