AST Completes Voice Call via Satellite Using Regular Cell Phone

[cdmagurus.com]

AST SpaceMobile has successfully completed a test of the first full two-way voice call using a standard, off-the-shelf cell phone connecting directly to a satellite in orbit (instead of to a land-based network.) Other recently-announced space connectivity solutions have focused only on messaging, not voice calls, and/or require new phones with added satellite technology. This test used an unmodified Samsung Galaxy S22 connecting directly to AST's BlueWalker 3 test satellite in orbit. It took place in Texas using AT&T radio frequencies; AT&T plans to use AST's system to provide coverage in remote areas. AST has completed additional tests that "confirm the ability to support cellular broadband speeds", as well as multiple cellular technologies from 2G to 5G. Tests also confirm compatibility with a variety of different phones and other cellular devices.
