Huawei’s 3G HiLink modems and wingles are USB devices that use the browser-based HiLink interface (no driver installation needed). Models like the E8238BWs, E8231, E8131, and E3531 plug into USB and broadcast WiFi, providing internet to multiple devices simultaneously.

Despite being 3G, these devices remain widely used in areas without 4G coverage. They ship carrier-locked and can be unlocked with a V4 (8-digit) unlock code.
