With the Huawei E5577Cs-321 White you can create a WiFi hotspot for up to 10 devices. Plug a 4G SIM card into this hotspot and use it on the road, on a (business) trip, or during a festival, for instance. Thanks to WiFi Offload, the device automatically switches to a free WiFi network when you come within range. This means one less action for you, and saves costs in your data use. To connect to the E5577Cs-321, download the app and scan a QR code. On the clear LCD screen, you can read 3 messages at the same time. It also shows useful information, such as the battery life and connection status.
