The Japanese operator Rakuten Mobile announced compatibility with the Apple satellite messaging service on several iPhone models and the Apple Watch Ultra 3. The new feature allows users to send and receive SMS and iMessage messages even in places without mobile network coverage or Wi-Fi. The feature represents an important expansion of the security functions already existing in the brand’s devices.
Users with iPhone 14 or newer models, in addition to the Apple Watch Ultra 3, can now count on this additional connectivity. The functionality is especially useful in emergency situations or in remote areas where conventional communication is unavailable. Implementation occurs through direct integration with the satellite infrastructure maintained by Apple.
Device support and technical requirements
The satellite messaging service works on iPhones released from model 14 onwards and on the Apple Watch Ultra 3. To use the feature on your smart watch, you must have an active contract with a compatible mobile phone operator.
The satellite connection allows you to send short texts and share your location with registered contacts. The system automatically directs messages to an Apple relay center when it detects the absence of a conventional signal.
Expanded functionality in emergencies
In addition to sending SMS and iMessage messages, the feature expands the SOS capabilities of Emergência and the Localizar app. Usuários can contact Apple’s specialized team by text in areas without coverage.
This communication can be forwarded to local emergency services as needed. Sharing your geographic position with family or friends also benefits from satellite technology, ensuring greater security in risky scenarios.
Free use period and conditions
Apple offers the satellite communication service free of charge for two years from device activation. Para iPhones 14 and 15 activated before midnight on September 9, 2025, the exemption period is extended for an additional year.
After the end of the promotional period, sending SMS messages via satellite follows the normal rates charged by the operator. Rakuten Mobile does not charge extra fees for activating the functionality during the initial free phase.
Service operational details
- Messages sent via satellite are limited to short texts to optimize transmission.
- The Localizar feature allows accurate sharing of coordinates even in isolated regions.
- Integration with Apple Watch Ultra 3 requires pairing with a compatible iPhone and an active data plan.
- The system automatically prioritizes satellite connection when terrestrial networks are not available.

Integration with existing Apple resources
The new Rakuten Mobile support expands the security tools already present on Apple devices. Usuários who already used SOS via satellite now have the possibility of exchanging direct messages.
The function allows textual contact with company specialists before activating rescue services. Essa additional layer of communication can reduce response time for serious incidents.
Rakuten Mobile has confirmed that the update is now available to eligible carrier customers on Japão. Activation occurs automatically on devices compatible with the latest version of the iOS and watchOS operating systems.
Availability and next steps
Rakuten Mobile customers with iPhone 14 or higher and Apple Watch Ultra 3 can check compatibility directly in the device settings. The operator advises that the satellite connection requires a clear view of the sky for best performance.
The announcement reinforces the Japanese company’s commitment to offering advanced connectivity technologies to its users. The expansion of Apple’s satellite service through Rakuten Mobile expands security options for consumers in the local market.
The implementation represents yet another advance in the convergence between traditional operators and space communication solutions. Usuários gain greater peace of mind knowing that they can maintain contact even in situations where conventional networks fail completely.
