Elon Musk says his Starlink satellite venture could need between $20 billion and $30 billion in investment.
Investment costs before Starlink achieves fully positive cash flow would be between $5 billion and $10 billion, Musk says.
"It's a lot, basically," Musk said, according to Reuters, in a video interview from California at the Mobile World Congress, which is the telecom industry's largest annual gathering.
SpaceX, Musk's space-travel-services company, began to take preorders for its Starlink satellite internet service from more countries starting in February.
Preorders of a beta of the service called Better Than Nothing will now be available in Australia, New Zealand, Mexico and parts of the U.S. and Canada where it is not yet up and running.
Better Than Nothing launched in October and had been available in parts of the northern U.S., southern Canada and parts of the U.K.
People interested in the service who are outside the current service areas can put down a $99 deposit to get access to the service once it becomes available. That's expected later this year.
The company uses a network of satellites to provide internet access. Starlink costs $600 up front, plus $499 for an antenna and router, and then $99 a month.
Starlink is currently in the regulatory portal in the Caribbean, Austria, Spain, Ireland, Italy, the Philippines, India, Japan, South Africa, Brazil and Columbia, according to a report from Teslarati.
