Messages via satellite, introduced with iOS 18, allows users of iPhone 14 and later models to send and receive text messages without cellular or Wi-Fi connectivity. However, this feature is currently limited to the United States and Canada.
Key Features of Messages via Satellite
- Compatibility: Available on iPhone 14 and newer models running iOS 18.
- Functionality: Users can send both iMessages and SMS messages via satellite. iMessages are encrypted, while SMS can be sent to any mobile number, but replies can only be received from pre-designated emergency contacts unless the user has initiated the conversation.
- Limitations: The service does not support sending photos, videos, or group messages. It requires a clear line of sight to the sky for effective operation and cannot be used indoors or under heavy foliage[1][2][4][6].
- International Use: As of now, Messages via satellite is primarily designed for use in the U.S. and Canada. There is no indication of when or if this feature will be expanded to other international markets[5][6].
In summary, while you can use Messages via satellite for communication in remote areas within the U.S. and Canada, its international availability is not confirmed at this time.

What are the differences between using iMessage and SMS via satellite
The differences between using iMessage and SMS via satellite on iPhones primarily revolve around functionality, encryption, and message handling. Here are the key distinctions:
1. Encryption and Security
- iMessage: Messages sent via iMessage are end-to-end encrypted, meaning only the sender and recipient can read them while in transit[1][2].- SMS: SMS messages sent via satellite do not have the same encryption and are not as secure as iMessages[1].
2. Message Types Supported
- iMessage: Supports sending texts, emojis, Tapbacks, and is integrated with iMessage effects (like bubble and screen effects) when using satellite[5]. However, it does not support sending photos, videos, or group messages[3][4].- SMS: Also allows sending texts and emojis but lacks support for advanced features like Tapbacks or effects. Like iMessage, SMS cannot send multimedia messages (MMS) such as photos or videos[1][4].
3. Recipient Requirements
- iMessage: To receive iMessages via satellite, the recipient must have an iPhone running iOS 18 or later. If they do not meet this requirement, the message will default to SMS[3][4].- SMS: Recipients do not need a specific version of iOS to receive SMS messages; any mobile phone can receive them. However, for a non-emergency contact to reply to an SMS sent via satellite, the sender must initiate the conversation first[2][3].
4. Sending Process
- iMessage: When you send an iMessage via satellite, it automatically connects to the nearest satellite if you are outside cellular coverage[1][3].- SMS: The process is similar, but you must first send an SMS message to allow other contacts (who are not in your Family Sharing group or emergency contacts) to respond[2][3].
5. Usage Context
- Both services are designed for use when cellular and Wi-Fi coverage is unavailable, primarily in the U.S. and Canada. They provide a way to stay connected in remote areas, but neither should be used for emergenciesâEmergency SOS is recommended for urgent situations instead[1][4].In summary, while both iMessage and SMS can be used via satellite on compatible iPhones, iMessages offer better security and more features compared to SMS messages.
