Concise Review of The Huawei E8278s-602 USB Mobile Wi-Fi Dongle

Four months ago, my Huawei E5730s-2 Mobile WiFi shut down on me and refused to come on. After several attempts to fix it, I succeeded but quickly started looking for a backup mobile wifi should in case it goes completely dead on me in the future. This time around I had my eyes on a mobile wifi with a beefier battery capacity.

That’s how I stumbled on USB Mobile Broadband WiFi Dongles. These are normal USB modems with added WiFi functionality and the ability to be powered by wall adapters, car chargers, power banks and practically any power source with a USB port/outlet.

After much bargain research, I settled on the Huawei E8278s-602 which cost me $51 on sale. It arrived 3 weeks later without a box, manual etc. Just the new branded but unlocked USB Mobile Wifi stick. See images below
