Review on GlocalMe U3 Mobile Hotspot 4G LTE Wireless Portable WiFi - No SIM Card Required, Connects up to 10 Devices, Establishes WLAN Anywhere, Intelligent Local Network Auto-Selection, comes with 8GB US & Global 1.1GB Data by Dan Bobbert

Don't waste your money. It's unreliable until it just dies, and is best used as a paperweight or doorstop. I bought one of these for a longer trip abroad. He seemed to work for 1 week and then he died. Customer service was a joke. Her suggestion to fix this was to plug it in and leave it overnight. So much time was spent using my data from another source, which I was trying to avoid. I paid $165 for the device itself, $90 for data, some of which was unused after death, and a $20 protective case. It didn't serve its purpose as a reliable Wi-Fi enabler, so it's nothing more than a $275 paperweight that's not even fun to look at. At best, he was temperamental and then just died. Save time or money and look elsewhere.
