Can an iPhone Really Replace Your Satellite Messenger?

The Future of Communication for Backpackers: Is Apple’s iOS 18 a Game-Changer?

Backpackers and outdoor enthusiasts have been buzzing with anticipation over Apple’s release of iOS 18, which introduced a groundbreaking satellite messaging feature for iPhone 14 and newer models. With the ability to send non-emergency text messages from remote wilderness areas—where traditional cellular service often falters—this feature could significantly enhance safety in the great outdoors. 

However, the pressing question remains: 

Can it replace dedicated satellite messengers, like Garmin inReach devices, that have long been essential for backcountry communication?

How the Feature Works

After testing the new satellite messaging capability in Colorado's West Elk Mountains, the initial results were promising. When standing above 8,000 feet, I found myself in a dead zone, completely devoid of service. With the SOS icon visible, I was able to access the satellite messaging prompt in iMessage, which guided me towards the nearest Globalstar satellite overhead. I managed to send and receive texts with my mom seamlessly, complete with emojis—an experience that felt as fluid as regular texting.

However, the satellite messaging feature does come with limitations. It only activates in areas with absolutely no service, and you cannot use it if you have any cellular signal, even if it’s too weak to send a message. Additionally, airplane mode must be disabled to access the feature, which is counterintuitive since many hikers use this mode to conserve battery life.

The Deal-Breakers

Despite its innovative potential, the satellite messaging feature has significant drawbacks that should make outdoor enthusiasts cautious:

1. Orientation Requirements: Users must physically orient their phones toward the satellite to send and receive messages. This could be particularly challenging if you are injured or immobilized, where movement may not be feasible.

2. Battery Drain: Using this feature drains the iPhone’s battery much faster than typical usage. In remote settings where charging options are limited, this poses a serious risk, especially when smartphones are also used for navigation and photography.

3. Durability Concerns: Even with rugged cases, smartphones are vulnerable to drops, extreme temperatures, and the harsh conditions of the outdoors. In contrast, dedicated satellite messengers are designed to withstand these elements and often have preset message options for emergencies.

4. Limited Coverage: Currently, Apple’s satellite messaging only works within the United States and Canada. For global adventurers, this limitation could be a critical factor when choosing communication devices.

Redundancy is Key

The essence of safety in the wilderness lies in redundancy. Relying solely on an iPhone for satellite messaging could leave you stranded without communication if your device fails or loses battery. While iOS 18’s capabilities may be useful in emergencies, having a dedicated satellite messenger like the Garmin inReach ensures a reliable backup. The inReach devices are designed for extreme outdoor use and can operate independently of your smartphone, lasting up to 600 hours on a single charge.

Conclusion: An Essential Tool, Not a Replacement

Apple’s iOS 18 satellite messaging feature is indeed a revolutionary step forward in outdoor communication, potentially saving lives in specific scenarios. However, it should not be seen as a replacement for dedicated satellite messengers. For backpackers and adventurers, the best strategy remains a combination of both technologies: use the smartphone for convenience and casual messaging while keeping a dedicated satellite device for critical communication.

As technology advances, the future may see smartphones integrate more robust outdoor features, but for now, the durability and reliability of dedicated satellite messengers ensure they will remain an essential tool for any serious adventurer. After all, when it comes to safety in the wild, it’s better to be over-prepared than under-equipped.
