Dual SIM smartphone: what is it and what is it for?


More and more dual SIM smartphones are available in the world and, although it might seem crazy to have two mobile lines at the same time, they can be more useful than they seem. Although some allows only one SIM for 4G LTE, while the second is only connected to 3G, many others already have dual 4G LTE support so you can navigate with the best speed in the two lines. But what is the dual SIM and how is it used?
