iPhone 17 and 5G satellites: What Starlink has in store

Apple’s “Awe Dropping” event (September 9, 2025, 10am Pacific Time, 9pm UAE) is anticipated to provide crucial hints to how Apple could regain momentum in artificial intelligence. It could also give some insights on forward collaboration with SpaceX. Though it is uncertain that Apple will address Starlink 5G direct-to-cell (D2C) features of the newest iPhone iterations remains to be seen.

Emergency SOS

iPhone 14 and previous devices already support satellite connectivity for emergency SOS, roadside assistance, and messaging via Globalstar. This is free for two years with device activation, and continues to be a distinctive benefit, though it is not available in specific areas like China and Russia, according to Apple Support.

Apple 5G Modem

Apple has been developing its own 5G modems after getting Intel's modem business in 2019 and is speculated to finally launch them in certain iPhone 17 models.


Reports indicate that some iPhone 17 models, particularly the ultra-thin iPhone 17 Air, will have Apple’s in-house 5G modem, eventually replacing Qualcomm modems that's used now across the iPhone series. This transition is anticipated to be incremental, with the fully Apple-designed chip being a potential selling area for the iPhone 17 Air.

Extension of LTE

A latest option presented in iPhone cellular settings to control the satellite feature. It operates automatically, needs no manual alignment, and treats Starlink satellites as an extension of the LTE network with T-Mobile's 1900 MHz spectrum.

Initial Starlink Rollout

In late January 2025, Apple added support for Starlink's DTC in iOS 18.3, enabling select T-Mobile users to send messages through satellite in regions without cellular coverage. The feature was launched in “beta” to a restricted group of T-Mobile users, who received notifications such as:

“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.”

Is this a Breakthrough?

Previous reports explained the feature initially as a "game changer" in regard to its seamless integration. However, clarifications highlighted that it is carrier-specific and does not showcase a full Apple-Starlink partnership.

Elon Musk made confirmation on X that the current setup aids in medium-resolution pictures, music, and audio podcasts, with plans to include video and higher data speeds in future.

FAQs:

Q1. What is the Emergency SOS?
It enables users to contact help through satellite when cellular network is not available.

Q2. What is special about the iPhone 17 Air?
It may have Apple’s own 5G modem instead of Qualcomm chips.
