The 3 dongle is a useful portable device that allows you to connect to the internet within minutes. Compatible with Windows XP, Windows 7, Windows 8, and MAC OS, the 3 dongle functions much like a pay-as-you-go mobile phone, allowing you to specify the amount of online data you would like to purchase. You can simply select the amount of data usage that suits you, rather than signing a contract for a given period of time.
The 3 dongle is particularly useful as a backup when your primary internet connection is unreliable; however, it functions well as a primary internet connection. You can plug the dongle into a PC or laptop USB port to get back online. The 3 dongle is compatible with both 3G and 4G SIM cards.
