Users in emergency situations in off-grid areas can request help by sending a message to help teams via satellite on iPhone 14 and 15 models.
Apple announced that it will provide two years of free access to this feature to anyone who purchases iPhone 14 and 15 devices.
Apple did not say how much it will charge for this feature when the free access period expires.
"From a man in Los Angeles who was rescued after his car fell off a 400-metre cliff in Los Angeles to missing hikers found in the Apennine Mountains in Italy, we continue to hear stories of our customers being able to connect with emergency responders they might not otherwise be able to reach," said Kaiann Drance, Apple's vice president of worldwide iPhone product marketing.
"We are delighted that iPhone 14 and iPhone 15 users will be able to enjoy this groundbreaking service for free for another two years."
