I have just started using the Samsung Galaxy Tab 2. I got this Android tablet as a birthday gift. While looking at the specs I come to know that you cannot put SIM in it in order to connect to the internet or make video call. But it has wifi where I can connect this device to a wifi router or hotspot and use the internet as needed. The Samsung manual also says that this device does support the USB dongle. So I am planning to use the 3G dongle so that I can connect to the internet whenever I want without the need of wifi. Does anyone know which model or what manufacturer 3G dongle supported in this Tab. Do I need any extra accessories also?
