Jiawu 4G Mobile WiFi Hotspot with Unlocked SIM Slot

The Jiawu 4G Mobile WiFi Hotspot targets a specific need: internet access where broadband isn't practical. It's a lightweight, pocket-sized router with a SIM card slot that accepts a standard 3G or 4G card, then shares that mobile connection with as many as 10 devices simultaneously. Travelers, remote workers, outdoor streamers, and anyone wanting in-car Wi-Fi are the obvious audience. The pitch is simplicity — no broadband contract, no installation disc, just a SIM and a USB power source to get a network running.

On the practical side, the design leans hard into portability and flexibility. Power comes through any USB port, whether that's a wall adapter, a laptop, or a car charger, and the same unit can switch roles to serve as a USB modem when connected directly to a computer. Setup is plug-and-play, with no CD required. A 4G LTE chipset drives the connection, supporting 802.11 b/g/n standards with an effective Wi-Fi reach of about 10 meters and speeds rated up to 300Mbps. Firewall configuration support is included for users who want tighter control over security. It's worth remembering the SIM card is not supplied, so a data plan needs sorting before the first connection.
