Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for No-Phone Texting

This newest model of Garmin's flagship Fenix adventure watch brings a life-saving feature: phone-free messaging and SOS alerts via 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new mobile technology, along with an available state-of-the-art microLED display in a special edition. This is the brand's top model and engineered to be the single tool needed to explore virtually any location and monitor every activity.

This makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the cost of the regular Fenix 8.

Users get a lot of features for your money, with best-in-class fitness, activity and outdoor monitoring. The full offline mapping of the globe can automatically direct you return to the trail if you lose your way absent a phone, and appear excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as tested boasts an extra day of smartwatch battery life even with the screen always active, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital service service rather than relying on a watch plan linked to your mobile provider, like other smartwatches. However unlike competing satellite-enabled products, emergency communication is not included for free.

Rather, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and audio messaging, calls and LiveTrack position tracking – so your friends or family can monitor you while out running, biking or comparable pursuits – along with emergency orbital SOS messaging.

Check-ins and messages via orbital are then billed on top, with higher-tier subscriptions offering different allowances of satellite usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you simply head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, send texts and overall stay connected with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a mobile number is enough to sign up for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable canned replies you can use to speed things up. Spoken messages and calls perform OK, though as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the quality is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a URL to chosen contacts whenever you start an activity, so they can track your live location on a map. It’s great for following race performance, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned well, though the actual position has occasionally lagged when transitioning in and out of strong LTE coverage.

These features are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location check-ins and emergency SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is important to note that satellite coverage is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available through the support site. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal schemes on new purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re without coverage.

Outcome is an even more impressive outdoor device for those that want to be phone-free. If you want to have someone monitor you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is quite liberating to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the features. Fortunately it isn’t reliant on your phone carrier so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, cycling or trekking, but nevertheless desires to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors all activities with premier GPS, built-in flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: extremely expensive, LTE and orbital features need ongoing payment, restricted Garmin Pay financial compatibility, speech capabilities are slow, basic wearable functionality compared with Apple/Google/Samsung watches.
