AST SpaceMobile ($ASTS) update: Chris Ambar joins T-Mobile, FCC grants Grain 800MHz test authority, plus a major new strategic hire.

Anpanman opens with a real-world tale of losing cell coverage entirely during a family trip, using it to frame why AST SpaceMobile's direct-to-cell satellite mission matters. He then breaks down two huge news items from last week: former AT&T and AST board member Chris Ambar officially joining T-Mobile as Chief Enterprise Officer, and the FCC granting AST SpaceMobile a Special Temporary Authority to test on Grain Management's nationwide 800MHz spectrum, a move tied directly to build-out requirements and potential T-Mobile coordination.

Anpanman also covers the hire of Ozzy Ramos, a former Barclays and UBS vice chair of investment banking, as a strategic advisor for AST SpaceMobile, and what it signals about upcoming M&A, joint ventures, and spectrum deals. He walks through the broader legacy direct-to-device playbook seen at Ligado, Echostar, Globalstar, and Iridium, the SES-OmniSpace-Link transaction, and Viasat's L-band opportunity.

The episode wraps with an audience Q&A covering ASTS stock institutional ownership jumping to 52.6%, the Japan joint venture, and the status of Bluebird satellites 14 through 16 ahead of a possible September launch.
