Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

The latest iteration of the premium Fenix outdoor watch introduces a potentially lifesaving capability: phone-free communication and SOS messaging using 4G LTE or orbital links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge cellular technology, along with an available state-of-the-art microLED screen in a limited edition. This is the brand's premier device and designed to be the single tool needed to explore virtually anywhere and track every activity.

That positions it as an very pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the price of the regular Fenix 8.

You do receive a significant features for your investment, with industry-leading workout, activity and outdoor monitoring. The complete offline maps of the world can seamlessly guide you return to the path if you get lost absent a phone, and look great on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as tested does have an extra day of watch battery life despite the display on all the time, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your phone provider, as with other wearables. But unlike competing satellite-enabled devices, emergency messaging is not provided for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, calls and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, cycling or similar activities – plus emergency satellite SOS alerts.

Check-ins and texts via orbital are then billed on top, with more expensive plans offering different allowances of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the service.

Once you have got it set up, you just head out the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you can place and receive calls, send texts and overall stay connected with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via typed or voice communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a phone number is sufficient to sign up for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable canned responses you can use to speed things up. Spoken recordings and calls perform acceptably, though as with most wearables, you’re unlikely going to wish to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own send a link to chosen contacts every time you start an activity, so they can follow your real time position on a map. It’s excellent for monitoring race progress, but it mostly acts as a utility for someone you trust to be aware of your location in case something happens. It has generally worked effectively, though the actual location has sometimes been delayed when transitioning in and out of good LTE signal.

All of these features are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A guide displays you how to find the line of sight 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 crucial lifeline, however it is important to remember that satellite service is limited 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 services available through the customer service site. The battery is rated to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused components. Garmin offers disposal programs on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re out of coverage.

The result is an even more impressive adventure device for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

This is very freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to enable the service. At least it is not reliant on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, biking or hiking, but nevertheless wants to be locatable and contactable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED display, tracks all activities with best-in-class GPS, integrated torch, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and satellite functions need ongoing payment, limited Garmin Pay bank compatibility, speech features are sluggish, limited smartwatch features versus Apple/Google/Samsung watches.
