Asus has introduced a variety of Android smartphones, mainly using Intel processors instead of the usual ARM ones, and they often come with dual SIM slots. The company has made a significant impact in major mobile markets, especially in countries like India, China, and other parts of Asia. Their popular smartphone line is called the ZenFone series. Before the ZenFone, Asus had launched feature phones like the Asus v70 and smartphones that operated on Windows Mobile back in the mid-2000s.
