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 Riko Mizuseki ᠌

My hopes of receiving a straightforward and trustworthy item were dashed. I listened to music for quite a while and attempted calling the Huawei support lines, but I was unable to connect. With the latest firmware, the router claims to be up-to-date. There is no way to fix this issue now. Don't bother planning on using any sort of storage space with Windows 10. Contains a number of advantages: It's small, has an easy-to-read display with helpful data (I found this to be the case during my time with the device), and has ports for connecting external antennas. Like with most "whistles," the quality of the message is unremarkable. It continues to function normally even after being disconnected from the network for a period of two to three days. The disadvantages are as follows. Information pertaining to E5577Cs-321: As far as Huawei routers are concerned, using SD storage is irrelevant. There is ostensibly a map there, but I couldn't figure out how to access it in Windows like I would a regular disk. Shared file hosting is accessible from a mobile device but not on Windows. The feature has several glitches. That's why I went out and bought a card with 128 gigabytes of storage space. When I finally did, it was pointless. When I change the router's settings in Windows, it immediately locks itself in a closed posture, preventing me from switching back to an open configuration through the web interface or a USB port. Reverses course once the apply button is pressed. A hard restart does not fix the issue. If you only sync your Huawei phone once to the cloud, Windows 10 won't recognize it. Unlike other variants that include a USB drive, this one doesn't have simplified controls.
