Your Upgrade for Stable 4G Internet
The Huawei E3372 is no ordinary surfstick – it is the crucial upgrade for your laptop or PC to get a fast and, above all, stable internet connection anywhere. Forget unreliable public Wi-Fi or tethering via your smartphone that drains the battery. This 4G USB adapter is designed as a pure client to provide your device with the best possible mobile connection. It is the direct, uncomplicated bridge to mobile internet, without frills, but with maximum performance for a single device.
Maximum Reception Performance: The 4G Stick with Antenna Connection
The outstanding feature of the E3372 are its two external Antenna connections (TS-5/CRC9). Especially in rural areas, in the basement office, or in a camper, mobile reception is often weak. This is where the stick plays to its greatest strength: simply connect suitable 4G Outdoor Antennas and experience a dramatic increase in speed and stability. The integrated 'Receive Diversity' technology already ensures good basic reception, but with external Antennas, the E3372 becomes the ultimate solution for demanding reception situations.
Simplicity Meets Pro Functions: The HiLink Web Interface
Complicated software installations are a thing of the past. Thanks to Huawei HiLink, the E3372 is ready for operation immediately after plugging in. You manage everything conveniently via a clear web interface in your browser – just like with a modern router. Here you can not only check your data consumption or send SMS, but also view in-depth technical data such as signal strength (RSRP), signal quality (RSRQ), and signal-to-noise ratio (SINR). These values are invaluable if you want to align an external Antenna with millimeter precision for the best performance.
Universally Applicable: On the Go, At Home, or as a Fallback
Whether as a mobile internet stick for the laptop on the train, as the primary internet access in a holiday home, or as a fail-safe backup solution for your home router (e.g., connected to a Fritz!Box) – the Huawei E3372 is a true multi-talent. Its broad frequency support makes it a reliable companion throughout Europe. Many of our customers in the Yacht / Camper / Motorhome sector swear by this stick in combination with a compatible 4G / 5G Routers to establish a stable connection even in remote locations.
