Starting July 31, 2025, Starlink, SpaceX’s satellite internet service, begins offering free connectivity for compatible smartphones in Brazil and other countries, promising to revolutionize access in remote areas. Partnering with T-Mobile, the Direct to Cell service allows around 50 smartphone models from brands like Apple, Samsung, Motorola, and Google to connect directly to satellites without additional antennas or accessories. The feature activates automatically in areas without traditional mobile coverage, initially supporting text messaging, location sharing, and emergency services. Activation requires only an updated device and enabling automatic connection in settings. The project aims to serve isolated regions, promoting digital inclusion and safety in critical situations.
Starlink’s technology uses a constellation of low-orbit satellites to provide signal in areas where traditional cell towers cannot reach. This innovation eliminates reliance on terrestrial infrastructure, enabling communication in rural areas or during natural disasters.
- Initial features: SMS sending, GPS location, and emergency calls.
- Supported devices: Recent iPhone, Galaxy, Pixel, and Motorola models.
- Activation: Automatic connection when traditional carrier signal is lost.
- Future expansion: Voice calls and internet browsing by the end of 2025.
The service’s rollout in Brazil aligns with the global schedule, focusing on areas with low coverage. The initiative is seen as a milestone for global connectivity, particularly in regions with limited internet access.
How satellite connectivity works
Starlink’s Direct to Cell technology turns compatible smartphones into terminals that connect directly to satellites without additional equipment. When a device loses a conventional carrier signal, it automatically searches for the satellite network, displaying a satellite icon and “T-Mobile SpaceX” on the screen. The process is native, requiring no apps or complex configurations. The connection is optimized for open areas with a clear view of the sky for better signal quality.
To use the service, the smartphone’s operating system must be updated. For iPhones, iOS 18.3 or higher is required, while Android devices need the latest versions, such as One UI 7 for Samsung phones. Enabling the emergency network feature is straightforward, typically found in the “Connections” or “Mobile Networks” settings.
Testing began in January 2024 in select regions, with promising results in the United States. In Brazil, the gradual rollout starts in July 2025, prioritizing areas with limited telecom infrastructure, such as rural zones and indigenous communities.
Compatible devices
The list of smartphones compatible with Starlink’s free service includes models released in recent years, all supporting 5G and advanced sensors. The variety of brands ensures broad accessibility, though the requirement for recent updates may limit access on older devices.
- Apple: iPhone 14, 14 Plus, 14 Pro, 14 Pro Max, 15, 15 Plus, 15 Pro, 15 Pro Max, 16, 16 Plus, 16 Pro, 16 Pro Max.
- Samsung: Galaxy A14, A15, A16, A35, A53, A54, S21 (FE, Plus, Ultra), S22, S23, S24, S25 (all variants), Z Flip3 to Z Flip6, Z Fold3 to Z Fold6, X Cover6 Pro.
- Motorola: Razr 2024, Edge 2024, Moto G Stylus 5G, Moto G Power 5G, Moto G 5G 2024.
- Google: Pixel 9, 9 Pro, 9 Pro XL, 9 Pro Fold.
T-Mobile devices, such as the REVL 7 5G and REVL 7 Pro 5G, are also compatible but not available in Brazil, emphasizing the need to verify device compatibility before attempting to access the service.
Benefits for remote areas
Starlink’s satellite connectivity is particularly valuable in regions with scarce telecom infrastructure. In Brazil, rural areas, indigenous communities, and border regions will benefit most. The technology enables basic communication, such as texting and emergency calls, even without traditional carrier signals.
The initiative is strategic during natural disasters, like floods or landslides, when terrestrial networks may fail. Rescue teams and residents can use the satellite network to coordinate actions, share locations, or request help, enhancing safety and efficiency in critical scenarios.
Additionally, free connectivity can boost digital inclusion, enabling small businesses, students, and professionals in remote areas to access digital tools. While the initial service is limited to basic functions, the planned expansion to internet browsing and voice calls opens new possibilities for education, telemedicine, and local commerce.
Steps to activate the connection
Activating Starlink’s free connection is simple but requires attention to detail. Users must ensure their devices are ready to recognize the satellite network automatically.
- Update the system: Ensure the phone has the latest iOS or Android version.
- Enable automatic connection: Go to “Connections” or “Mobile Networks” settings and activate the emergency networks option.
- Open area: Position yourself in a location with a clear view of the sky for optimal signal reception.
- Check compatibility: Confirm your smartphone model is on the supported devices list.
The lack of need for additional accessories or apps makes the service accessible, though signal quality may vary in areas with obstructions like dense forests or tall buildings.
Future plans and expansion
Starlink plans to expand Direct to Cell features by late 2025, adding voice calls and internet browsing. This will depend on increased satellite capacity and integration with local carriers. In Brazil, no partnerships with local operators have been announced, but compatibility with carriers like Verizon and AT&T in the U.S. suggests similar agreements may follow.
The initial service is free, but advanced features, like mobile data and VoIP calls, may introduce costs. In the U.S., prices are speculated to range from $10 to $15 per month for non-premium T-Mobile plan users, with discounts during the beta phase. In Brazil, pricing remains undisclosed, but basic functions like SMS and emergency services will stay free.
The technology also paves the way for Internet of Things (IoT) device connectivity, such as agricultural sensors and medical equipment, expanding its impact on sectors like farming and healthcare. Starlink’s satellite network, with thousands of units in orbit, ensures global coverage and capacity for growing user demand.
Technology behind Direct to Cell
The Direct to Cell innovation lies in integrating eNodeB modems into Starlink satellites, functioning as space-based cell towers. These satellites operate in low orbit, reducing latency and boosting connection efficiency. The technology uses mid-band frequencies, achieving speeds up to 4 Mbps in the initial phase, sufficient for real-time messaging and location sharing.
The absence of additional hardware requirements in smartphones is a key advantage, as compatible devices already have built-in sensors to detect satellite signals. The T-Mobile partnership, though limited to specific markets, enables seamless transitions between terrestrial and satellite signals.
The technology is designed to withstand adverse conditions, like heavy rain or strong winds, though signal quality may be affected by physical obstructions. Starlink recommends using the service in open areas to maximize performance, especially in remote regions.
Global impact of the initiative
Starlink’s free connectivity launch marks a significant step in reducing the digital divide. In countries like Brazil, where vast areas lack telecom infrastructure, the service can transform the reality of isolated communities. Real-time communication in areas without coverage strengthens safety and access to essential services.
The initiative aligns with SpaceX’s mission to democratize internet access globally. With the beta program expanding through July 2025, more users can test the technology, contributing to its refinement and scalability.
Collaborations with international carriers, such as Optus in Australia and Rogers in Canada, indicate Starlink’s pursuit of global partnerships to broaden the service’s reach. In Brazil, expectations are high for local carrier agreements to enhance integration and provide technical support to users.
