Review on Huawei E5577 E5577-321 Mobile WiFi Hotspot - 12 Hour Working Time, Portable Sim Card Router Mifi - 4G LTE in Europe, Asia, Middle East, Africa & 3G - Not Compatible with USA Sim Cards by Ada Marciniak ᠌

Good model, I recommend Has pros: A small, compact battery lasts decently, there is a connector for 2 antennas, the most important plus is the ability to use SIM cards from different operators, and there you already need to determine the quality of network coverage Has some cons The router incorrectly shows the amount of traffic spent (only approximately), you will need to contact your operator to clarify the rest of the traffic, or maybe only I have such a problem
