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 Aneta Trzonkowska ᠌

I expected to get a simple and reliable product, but it did not work out. I tried to call the Huawei service centers - I listened to music for a long time, and did not get through. The router, when ating the firmware, says that the newest one is installed. Those. this problem is unrecoverable. If you expect to use storage in win 10 - you can forget about it! Has pros: It is compact, there is a screen on which there is useful information (I really liked it when using it), there are outputs for external antennas. The quality of communication does not differ from most "whistles". With prolonged use of 2-3 days from the network without shutting down / rebooting, it works stably. Its cons: Specifics about E5577Cs-321: The use of SD storage in a Huawei router is a moot point. Nominally, there is a map, but how to enter through Windows, as on a normal disk, I could not. File hosting works through a smartphone, but does not work in Windows! The function is buggy. I even bought a 128GB card for this case. Then I realized that in vain. In the settings through Windows, as the router went to the closed position of access to the card, it does not return either to the open mode via WEB or the open mode via USB. Jumps back again after pressing the apply button. Deep reboot does not solve the problem. After a one-time connection of the smartphone using the application from Huawei to the storage, it is no longer in win 10. Simplified functions, as implemented on other models with a usb drive, are not here!
