April 2023 History made: First-ever space- based voice calls using everyday smartphones O vodafone "Today, we have taken another major step in mobile communications. 30 years after Vodafone sent the world's first text message, we supported AST SpaceMobile in successfully making the first ever direct-to- smartphone test call using satellite communications. This is just the start. As a lead investor in AST Space Mobile, we will continue to break technological boundaries by connecting many more millions of people across the planet when the service becomes commercially available." -Margherita Della Valle, CEO AT&T "AT&T's heritage began with the birth of the telephone 147 years ago and has continued with many other firsts including: trans-continental call, overseas call, call from the moon, and partnering to deliver the only network built with and for America's first responders. We connect people to greater possibility, and this important milestone with AST Space Mobile is a big step and we can't wait to see what's next in our space-based journey." -Chris Sambar, Head of AT&T Network Rakuten "It was a unique thrill and honor to have the Rakuten team talk with Abel in a world- first direct-to-satellite experience. Congratulations to AST SpaceMobile and all of its strategic collaborators on this groundbreaking event. As technological advancements like space connectivity become possible with pioneers like AST Space Mobile, Rakuten will also progress even further along the road to democratizing connectivity for all." —Mickey Mikitani, Chairman & CEO AT&T Milestones AST SpaceMobile FST Spor The first voice call was made from the Midland, Texas area to Rakuten in Japan over AT&T spectrum using a Samsung Galaxy S22 smartphone 1876 First phone call First television transmission over transcontinental radio relay of President Truman 1951 1954 First solar battery First transmission of content over a satellite 1962 1977 First Fiber install in Chicago First ever two-way voice call on AT&T spectrum via satellite with an everyday cellphone by AST SpaceMobile 2023 8 ast-science.com ASTSpaceMobile "SATELLITE AST SpaMale Source: AT&T.
