Hello everybody,
i’m interested in enabling a 3G/4G/LTE connection for downloading information from my Raspberry/Navio2 platform through a web service. Is it possibile to install a USB Dongle ? Is it plug and play or should i download some specific drivers ?
Thank you so much.

sure it’s possible!
I’m using a huawei e3372 in hilink mode - it’s creating a eth device over usb - so it’s actually plug and play!

what do you mean exactly?
I just insert the usb stick into the usb port of the rpi and I’m online;

LOL, nice. I have not had the same or even close to similar luck. Been using the Netgear/Sierra Wireless modems, which work on the AT&T network here in the US.
Looks like more research is in order.
which modem do you use?
you might have to look into wvdial - or sakis3g script (or umtskeeper) for dial up connections (ppp);
on aliexpress you can buy hilink huawei (plug and play) devices (eg huawei e3372) for about 35euros…

The new modem is the Sierra Wireless Aircard340U.
The older modem is modem is Sierra Wireless Aircard313U.
And this is the 3G I’ve attempted to use, and no go.
check out this link for wvdial:

I recommend huawei’s hilink devices because it’s easy and they automatically keep up connection and reconnect if necessary…
