This is the customer question: Could you please tell me how can I connect Huawei dongle for internet connection? If you have the same as about that issue, you can do that like this.

You need to connect the 3G card to USB interface, the 3G must support WCDMA and the unit have to turn off. Then turn on the unit, the 3G network will be automatic connected.
The same as android dongle. But your Huawei dongle maybe can’t support our unit and you need to try it.
