KiwiSIM 4G LTE WiFi Router with Sim Card, Portable Modem WiFi Router, 300Mbps WiFi, CAT4, Support AT&T and T-Mobile, 3000mAh Battery, Data SIM Card Included

It works great. However I noticed when I unplug it, and it runs out of power in 12 hours or so, it turns off and won't come back on automatically when power is restored. I'm planning on using it in a remote location and using solar power, so sometimes the power is interrupted.

Works great! Easy setup. I just inserted the SIM card I also got from Kiwi and it worked right away, no need to configure settings or activate card like I was expecting. Only complaint was slow shipping.
