Anyone wishing to connect their mobile device to the internet is going to need a dongle. Dongles are small modems, which connect via a USB port. The modem allows data to be sent and received as long as it is close enough to a signal. Internet signals are like electromagnetic waves or radio waves, meaning they exist in the air to be caught by antennas and dispersed appropriately. When you have 3 dongles you have the ability to connect to any signal 3 sends out for mobile broadband purposes.
3 is going to be your mobile broadband provider offering you a secure network via the dongle. You will have a secure code to use in order to connect ensuring your privacy even in a mobile setting. The dongle will attempt to pick up the strongest signal to connect with.
