Headquartered in Pittsburgh, Pennsylvania, Smith Micro maintains multiple domestic and international offices.

Currently, the company focuses on digital lifestyle solutions[buzzword] and security technologies, and is integrated into the evolving wireless media industry, as indicated by partnerships with cellular service providers such as Verizon Wireless,[1] AT&T,[2] and Sprint Corporation,[3] now owned by T-Mobile US after the Sprint & T-Mobile merger in April 2020.

Smith Micro's initial focus was on dial-up modem and fax software technology, distributing predominantly to OEM computer software/hardware manufacturers.

While fax and modem-related products were still a part of their portfolio, the QuickLink Platform of wireless connection managers became a primary source of revenue in the early 2000s.

Smith Micro introduced multiple solutions for enhanced mobile communications, such as push-to-talk software, visual voicemail services, and video streaming.
