The Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

This most recent model of Garmin's top-tier Fenix outdoor watch brings a potentially lifesaving feature: phone-free communication and SOS alerts via 4G LTE or orbital links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge cellular tech, plus an optional advanced microLED screen in a special edition. This is the brand's premier model and designed to be the only gadget required to venture almost any location and monitor all your movements.

This makes it an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the cost of the standard Fenix 8.

You do receive a lot of functionality for your money, with best-in-class workout, activity and outdoor tracking. Its complete offline mapping of the world can automatically guide you return to the trail if you get lost absent a phone, and appear great on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed does have an additional day of smartwatch battery life even with the display on all the time, enduring a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

The company operates its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan tied to your phone provider, as with other smartwatches. But in contrast to Apple or Google's satellite-capable devices, SOS communication is not included for free.

Instead, plans start at £7.99 or similar a month, which includes unlimited LTE text and audio messages, call functionality and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while out jogging, cycling or similar pursuits – plus emergency orbital SOS alerts.

Location updates and messages via orbital are then billed on top, with more expensive plans offering various quotas of orbital use, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the functionality.

After you have got it set up, you just head out outside without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you are able to place and receive calls, send texts and generally stay connected with your relatives and friends.

When you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message back and forth using typed or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, only a phone number is sufficient to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a collection of customisable canned replies you can use to speed things up. Spoken recordings and calls perform acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a link to chosen contacts whenever you begin an activity, so they can track your real time position on a map. It’s great for monitoring race performance, but it primarily serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has typically worked effectively, although the real location has occasionally been delayed when transitioning in and out of good LTE signal.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, though it is essential to note that satellite service is restricted to the US continent, the majority of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available through the customer service site. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled components. Garmin provides disposal programs on recent purchases.

Cost

This Fenix 8 Pro costs 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

The Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without coverage.

The result is an even more remarkable adventure tool for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is quite liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone carrier so works with all brand of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when jogging, biking or hiking, but still wants to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: very costly, LTE and orbital features require monthly payment, limited Garmin Pay bank compatibility, voice features are slow, limited smartwatch functionality versus Apple/Google/Samsung watches.
