Since iOS 18 it is possible to send messages via a satellite connection if there is no mobile and Wi-Fi cover. You can send and receive text messages and tapbacks via iMessage and SMS via the connection.
However, the function is only available in the United States and Canada for the time being. If you go on holiday in these countries, you can use it. You can use the messages via satellite service for free for the first two years. This free period starts after the activation of an iPhone 14 or newer.
What is Messages via satellite
With the messages via satellite service you can send messages via the standard Message app from iOS. If the person you want to send a message does not have an iPhone (with at least iOS 18) or another brand of mobile phone, you can use SMS messages via satellite. Some message functions are not supported with the use of a satellite connection. For example, in a group message you cannot send or receive photos or videos, audio messages, stickers or messages.
Conditions Use messages via satellite
To be able to use messages via satellite, you must meet the following conditions:
- You have an iPhone 14 or newer (all models) with at least iOS 18. Please note! Satellite connection is not available on iPhone devices that have been purchased in Armenia, Belarus, mainland China, Hong Kong, Kazakhstan, Macao or Russia.
- At the location where you are, there is no mobile range and no WiFi connection available.
- Your iPhone must be provided with an active SIM card.
- To use iMessage via satellite, you must switch on iMessage before you are outside mobile and WiFi coverage. To use SMS messages via satellite, your provider must support this.
- For the time being, the function is only available in the US and Canada. Availability in other regions depends on regulations by government agencies and necessary approvals. Apple is working on making the function available in more regions.
Send messages via satellite
When your iPhone detects that you are outside of mobile and WiFi coverage, it warns you. The lock screen shows a message that you can send and receive messages via satellite.
To send a message, open the Message app. You will be asked to accept messages if you have not done that yet. On your iPhone you will see instructions on how to connect to a satellite. The strength of your connection is displayed in the Dynamic Island of your iPhone.
If you can be improved, arrows in the direction for a better signal. If you tap Dynamic Island, the connecting assistant will be opened that can also help you improve the reception of the satellite signal.
Sending messages via satellite is much slower than via a standard WiFi or a mobile connection. In ideal conditions with a direct view of the air and the horizon it can take 30 seconds for a text message to be sent. Under trees it can take longer than a minute before the message is sent. You may not be able to connect to a satellite under a heavy leaf deck or if you are surrounded by other obstacles.
