4G/LTE modem for Navio 2/rasperry pi 2

Hi,

Does someone know working modems?? Does ZTE831 work???

I’m new on this rasperry systems.

I ordered one of these after reading that they are very simple to setup on the RPi2 & it also acts as it’s own wifi router. I figured for the price it’s worth a try: http://www.ebay.com/itm/181539050737?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
