Mast Mobile was a telecommunications service company that provided integrated mobile communication solutions. The company's key feature was its ability to combine both personal and business phone numbers on a single mobile device, allowing users to manage different aspects of their lives seamlessly. This innovative service was geared towards professionals who needed to separate work and personal communications without carrying multiple devices. As of my last update, the website http://mastmobile.com is inactive, suggesting that the company may no longer be operational.
