Satellite Internet Service Promises Direct Connection on Compatible Smartphones, Even in Remote Areas, with Message Sending and Location Without Needing an App or Antenna, but Is Not Yet Available in Brazil.
Starlink, SpaceX’s satellite internet service, has begun to roll out direct access to mobile phones to send text messages and share location in areas without coverage from traditional carriers, using the low Earth orbit satellite constellation.
The feature, called Direct to Cell, works on LTE phones, without changing devices, installing antennas or downloading apps, and is operating commercially in the United States in partnership with T-Mobile (T-Satellite).
In Brazil, Starlink’s free internet on mobile phones is not yet authorized by Anatel and, therefore, is not available here at this time (August 10, 2025).

What Is Direct to Cell and How Does It Work
Direct to Cell turns satellites from Starlink into a kind of “cell tower in space,” with an eNodeB onboard that integrates with mobile networks as if it were a roaming partner.
The compatible cell phone connects automatically when there is no terrestrial signal, provided there is a view of the sky, and the experience is to send SMS as usual.
Starlink itself summarizes: “it works with existing LTE phones […] without hardware, firmware, or app changes”.
For now, the active offer allows text and location sharing in outdoor areas.
Data (optimized apps) are set to be rolled out in 2025 and voice is expected to arrive later, according to the company itself.
On the ground, T-Mobile reports that satellite connection may experience delays in sending and depends on open skies, with limitations in closed environments, canyons, dense forests, or aircraft.
Is It “Free Internet” for Everyone?
No. The term “Starlink free internet” refers to the commercial model with no additional cost on specific plans from the partner carrier in the U.S.
At T-Mobile, T-Satellite is included in the Experience Beyond/Go5G Next plans and can be activated as a monthly service in other cases.
In other words, it is not a “universal free service” and varies according to the plan.
Outside the U.S., availability and pricing depend on each carrier that strikes a deal with Starlink and local regulatory approvals.
In Brazil, Anatel reported that direct service to cell phones is not authorized and there is no approval for use on smartphones, although the agency expanded, in April 2025, Starlink’s satellite operating license in the country.
Therefore, Starlink’s free internet on mobile phones does not work in Brazil at this time.
How to Activate When Available
In markets where it already works, like the U.S., activation is automatic: the phone switches to the satellite network when it leaves terrestrial coverage.
T-Mobile advises keeping the operating system updated and, when required, use eSIM and allow automatic data switching.
On iPhone, signal bars appear with the indicator “SAT” and the network name “T-Mobile SpaceX”.
On Android, a satellite icon appears with the same network name.
There is no dedicated app or complex configuration.
In practical terms, the official recommendation is simple: send the message as always and the system will attempt to retransmit it until sending is completed.
Performance may vary based on the number of users, terrain, and sky conditions.
The service prioritizes outdoor use, with an unobstructed view.
Which Phones Are Compatible?
There is an essential point to avoid confusion: there is no “global and definitive” list of 50 models certified by Starlink for all countries.
Compatibility lists are published by partner carriers and may change as each manufacturer’s software updates.
In the U.S., T-Mobile reports over 60 compatible models today, including all lines from iPhone 13 to 16, Google Pixel 9 (and 9a), several Motorola 2024/2025 models (such as razr, razr+, edge, g 5G, and power 5G) and a wide range from Samsung (Galaxy A14 onwards, recent A-series, S21 to S25, FE, XCover, and Z Flip and Z Fold lines).
Compatibility may vary per device variant and by region.
And in Brazil? Even if your phone appears on foreign lists, Starlink’s direct-to-cell service does not operate here due to lack of authorization and an active commercial partnership with a local carrier.
Starlink’s free internet, therefore, cannot be legally used in the country via mobile at this time.
What You Can Do Now and What Comes Next
Currently, text and location are the features effectively available in the U.S.
T-Mobile has begun the gradual expansion of MMS (photos) for Android and plans satellite data for optimized apps next, a phase that Starlink points as data rollout in 2025.
Voice calls are expected as the next phase.
From the perspective of a user on an eligible plan, yes, it is “free internet” because the cost is already included in the plan.
For other users, there is a monthly fee.
Step-by-Step Verification Before Traveling
What to check in your case:
- System updates and the manufacturer’s firmware updates for the phone.
- If your carrier offers Direct to Cell and what the price is on your plan.
- If your device appears on the local compatibility list and if there are any eSIM requirements.
- If use only works outdoors and does not replace regular coverage for continuous browsing.
And Brazil, When?
Anatel expanded Starlink’s satellite operating license, but did not authorize direct service to cell phones.
As the agency has already clarified publicly, Starlink’s free internet on mobile phones is not available in the country.
Any information different from this is not accurate.
Without authorization and without a local partnership, Direct to Cell cannot be activated on Brazilian smartphones.
Quick Questions to Avoid Mistakes
Does Starlink’s free internet apply to my plan in Brazil? No, there is no active offer in the country.
Do I need to buy another phone? In theory, it works with existing LTE phones, but it’s the partner carrier that defines compatibility.
Do I need to download an app? No. The connection is automatic when there is no terrestrial network.
Can I browse the web? Not widely yet. The current focus is text messaging; expanded data is expected in 2025, and voice later.
In what situations does this help? In trails, remote roads, rural areas, and other locations without coverage — always with open sky and patience for potential delays.
List of Models: U.S. Reference
For those looking to use the service in the U.S., here are examples of models mentioned by T-Mobile as eligible (the complete list is longer and may change):
Apple
- iPhone 13, iPhone 14, iPhone 15, and iPhone 16 (all versions).
- Pixel 9, Pixel 9a, Pixel 9 Pro, Pixel 9 Pro XL, and Pixel 9 Pro Fold.
Motorola
- razr/razr+/razr ultra 2024/2025 family, edge 2025, g 2024/2025 (g 5G, power 5G).
Samsung
- Galaxy A14, A15, A16, A35, A53, A54, and recent A-series lines.

- Z Flip3 to Z Flip7 and Z Fold3 to Z Fold7.
- XCover6/7 Pro.
In Summary, What You Need to Know
Starlink’s free internet on mobile is currently available commercially in the U.S. through T-Satellite, without an app and without changing devices for compatible models.
In Brazil, Starlink’s free internet on smartphones has not been authorized and does not have a confirmed public date. To use it outside the country, check plan, compatibility, eSIM, and open sky conditions.
And you: if “Starlink’s free internet” arrived in Brazil tomorrow, would you use it on your mobile for trails and emergencies, or would you keep only your carrier’s network?
