iPhone users can now participate in a test of SpaceX's Starlink direct satellite connection, which is supported in the iOS 18.3 update released this week.

According to Bloomberg, Apple has been secretly working with SpaceX and T-Mobile US Inc, a program partner, to add support for the Starlink network to its latest software.

Before that, T-Mobile had said that the service would also be compatible with Samsung models such as the Z Fold and S24.

Apple already offers a satellite service through Globalstar that allows you to send text messages and call emergency services when there is no cellular coverage. Starlink differs from Globalstar in that it works automatically, without the need to point the iPhone at the sky to find a satellite.

T-Mobile began inviting users in the United States to test Starlink on January 16, and this week the carrier updated its website to confirm support for some iPhones with the release of iOS 18.3.

The first users received text messages from T-Mobile that said:

"You're in the T-Mobile Starlink beta. You can now stay connected with texting via satellite from virtually anywhere. To start experiencing coverage beyond, please update to iOS 18.3."

In a post on the X platform, Elon Musk noted that the current Starlink technology supports medium-resolution images, music and podcasts, and future updates will include video support. The full launch of the service is scheduled for February.

As a reminder, on January 27, SpaceX began beta testing its new Starlink service, which allows mobile phones to connect directly to the Internet via satellites.
