Review on 🌍 KuWFi 4G LTE Mobile WiFi Hotspot: Unlocked Router with SIM Card Slot for Travel in Europe, Caribbean, South America, Africa by Daniel Greene

To properly configure LTE for T-Mobile USA, be sure to change the following settings. See attached picture. LTE preferred > LTE FDD preferred Tested with a laptop. It's good for surfing the web with a laptop, I was also able to play some YouTube videos at 480P resolution (it takes a few seconds to load on screen, but they play without interruption) or with constant buffering.) Testing data transfer from one and then from two smartphones. Two phones playing Pokemon Go at the same time will get network error while playing, this KuWFi can not provide enough data to two smartphones at the same time. Only one phone is connected while playing, performance is acceptable although I get better response times with phone data. So if you need it for your laptop go ahead this will work, if you need to play online games with mobile devices this will not work well.
