Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Messaging

This newest version of the flagship Fenix adventure watch brings a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new cellular technology, plus an available state-of-the-art microLED display in a special edition. It is the brand's top device and designed to be the only tool needed to venture virtually any location and monitor all your movements.

That makes it an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

You do get a lot of features for your investment, with industry-leading fitness, movement and outdoor monitoring. Its complete offline maps of the world can seamlessly direct you back to the trail if you lose your way without a phone, and appear great on the sizable, sharp and super-bright display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life even with the display on all the time, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and orbital service plan rather than relying on a watch plan tied to your mobile provider, as with other wearables. But unlike Apple or Google's satellite-enabled devices, emergency communication is not provided for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes limitless LTE text and voice messaging, call functionality and LiveTrack location tracking – so your friends or loved ones can monitor you while engaged in jogging, biking or comparable pursuits – plus SOS satellite SOS messaging.

Location updates and messages via orbital are then charged on top, with higher-tier subscriptions offering various allowances of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

Once you have completed setup, you just head out outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you can place and receive calls, send texts and generally keep in touch with your family and friends.

Whenever you text someone, Garmin dispatches them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, just a phone number is sufficient to sign up for texts.

Messaging on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It has a set of customisable canned responses you can use to speed things up. Voice messages and calls work OK, though as with the majority of wearables, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the handiest feature. You can configure to on its own send a link to chosen contacts whenever you start an activity, so they can track your real time location on a map. It’s excellent for following race performance, but it mostly acts as a utility for someone you rely on to be aware of your location in case something happens. It has generally functioned effectively, though the actual location has sometimes lagged when transitioning in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance displays you how to find the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is important to remember that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally repairable with services available through the support site. The battery is rated to retain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers recycling schemes on recent purchases.

Cost

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

Conclusion

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re out of coverage.

The result is an increasingly remarkable adventure device for those that desire to be phone-free. If you wish to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is quite liberating to be outside without a phone, but that capability 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 all brand of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still desires to be trackable and reachable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED screen, monitors all activities with premier GPS, integrated torch, voice and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very costly, LTE and orbital features need ongoing subscription, restricted Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch functionality versus competing watches.
