Canadian mobile carrier Telus has paired with satellite manufacturer AST SpaceMobile to kick off testing of direct-to-device (D2D) services.

In an announcement, Telus noted that the two companies have completed their first integration test using Telus' wireless network and AST SpaceMobile's space-based network infrastructure as part of a satellite-to-smartphone test.

According to Telus, this test is a key milestone in showcasing the ability to access broadband data services, make voice calls, and send text messages directly between smartphones and satellites.

The partnership aims to leverage AST SpaceMobile's LEO satellite constellation to expand cellular broadband coverage for Canada's population, while enhancing access to critical emergency services.

In Canada, D2D presents itself as a key use case given large parts of the country are rural areas where terrestrial connectivity is not readily available.

"Connecting smartphones directly to satellites is opening up new possibilities for how Canadians stay connected," said Nazim Benhadid, EVP and chief technology officer, Telus.

"This successful milestone with AST SpaceMobile is a major step forward in extending cellular coverage to places where service isn't available today, reinforcing our commitment to bringing reliable service to more Canadians, no matter where they are."

AST SpaceMobile previously outlined plans to launch between 45 and 60 of its latest generation BlueBird satellites this year, though it has since readjusted that target to 45 by early 2027.

As for when D2D services, Telus said it expects to launch the service for its customers within the next year, noting that the service will be available for customers to use with eligible smartphones beyond the reach of traditional cell towers.

"This milestone demonstrates how mobile network operators can seamlessly extend their existing networks with space-based cellular broadband using everyday smartphones and reflects the strength and maturity of our technology," added Chris Ivory, chief commercial officer at AST SpaceMobile.

Beyond mobile, Canadian telco Telus has previously outlined plans to invest more than CA$70 billion (US$50.6bn) to expand and upgrade its network infrastructure and operations over the next five years.

Founded in 1990, Telus serves more than ten million mobile subscribers across the country. The carrier also sells fiber broadband and TV subscription services.
