With Openplotter 1.2 on RPi3 B + I have used so far a 4g Huawei E5377 router without problems, it is connected in usb and raspberry sees it as ethernet. I can remotely access with vnc by configuring the openplotter ports as virtual servers on the router.
Now I would like to use the data sim also for sending sms, so I thought to replace the router with a usb stick. My problems start here ...

I tried to run 3 different 4G keys without success:

Alcatel IK40V
I have tried very hard tests following several guides but if active usb-modeswitch at boot most of the times raspbian crashes

D-Link DWM-222
Configuring usb-modeswitch activates the serial port and also the network, then starting wvdial the connection remains inoperative.

Huawei E3372
Configure usb-modeswitch and the internet connection works but this dongle is seen as ethernet not as serial, so I do not think it is possible to make the sending of SMS work.
In addition, being seen as a router but without the possibility of setting up virtual servers, I do not see how it is possible to use remote access with VNC

I ask if anyone has a solution with one of these devices or anything else would be welcome, thank you!

PS I apologize for not good English
Update...
I managed to make the D-link DWM-222 work, just add the gateway manually with:
sudo route add default gw 10.64.64.64

The Huawei E3372 can also work in serial mode by following this guide:
http://www.draisberghof.de/usb_modeswitc...f=3&t=2596
also in this case the gateway must be added manually with:
sudo route add default gw 10.64.64.64

I still have to finish tests and checks and post more details.

I noticed however that openplotter does not show in the icon (or even in the configuration of network interfaces) the active network when it is ppp0
try sakis3g script?
