Be patient when it comes to satellite messages. It may take just a few minutes to send a message, especially with a clear sky and no tree coverage. But getting a connection to a satellite may be tough in some locations, and even the positioning of satellites or heavy cloud cover can alter the timeline of your message.
Keep in mind, there’s no guarantee you can get a signal to a satellite, so some cases may require a high level of patience or willingness to move in order to connect to the satellite.
