Portable 4G LTE USB modem with SIM slot

The KuWfi UF909-U9 is a compact cellular modem that creates a personal Wi-Fi hotspot from a compatible SIM card. It targets travellers, remote workers and anyone needing internet access on a laptop or tablet without relying on public networks. The device measures 96 by 31 by 13 millimetres and draws power from any standard USB port. Up to ten Wi-Fi-enabled devices can connect simultaneously.

Sustained connectivity on 4G FDD bands 2, 4, 5.

The modem supports download speeds up to 100 Mbps and upload speeds up to 50 Mbps on the listed North American LTE bands. In continuous use it maintains a stable link for multiple clients such as phones, tablets, smart speakers and cameras. Performance depends on carrier coverage and the selected data plan rather than burst-mode specifications. The web interface at 192.168.0.1 allows APN adjustments when the automatic profile does not connect.

USB-powered thermal profile with foldable antenna

Because the unit is powered entirely from a USB source such as a laptop, power bank or car port, its power draw stays within the limits of a standard USB supply. The foldable multi-directional antenna can be repositioned for better reception without adding bulk. Under normal loads the enclosure remains cool to the touch and produces no audible fan noise. Default Wi-Fi credentials are printed on the device for quick setup.
