Who Owns the Billing Relationship

Whoever sends the monthly bill gets to own the customer, the upsell, and most of the long term economics. In direct to cell, that usually means the mobile carrier, not the satellite operator. AST has signed carrier led deals with AT&T through 2030, and its own materials describe SpaceMobile as a wholesale service for mobile network operators. Starlink is different because T Mobile is selling the service today, but Starlink is also building toward a world where it can become the carrier layer itself.1 2 3 4

• AST fits the tower supplier model, not the retail phone plan model. The user keeps an AT&T or Verizon relationship, uses the same phone, and satellite coverage shows up as an extension of the carrier network. That makes AST economically closer to a wholesale capacity vendor than a consumer brand.2 3 4
• Starlink has already shown the first step of the same pattern. T Mobile opened its Starlink beta broadly, with satellite service bundled into some plans and sold to others for $10 per month, while SpaceX is compensated through carrier style wholesale terms in its current setup.1 5 6
• The strategic prize is escaping wholesale. SpaceX has spent years moving up the stack from launch into end markets like residential broadband, aviation, and now mobile. Research on SpaceX points to the same playbook here, use carrier partnerships first, then push toward owning the full service and billing relationship globally.5 6 7

The market is heading toward a split between satellite networks that sell capacity to carriers, and networks that try to become carriers themselves. If Starlink can turn direct to cell into a native global phone service, it captures far more revenue per user than AST. If carriers keep the interface and the invoice, AST remains the supplier and the carrier keeps the crown jewels.1 3 5 6 7
