Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for Phone-Free Messaging

This most recent version of the flagship Fenix adventure watch brings a potentially lifesaving capability: phone-free communication and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding new cellular technology, along with an optional advanced microLED display in a limited edition. It is the brand's top device and engineered to be the single gadget needed to explore almost anywhere and monitor every activity.

That positions it as an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the cost of the regular Fenix 8.

Users get a significant functionality for your money, with best-in-class workout, activity and adventure monitoring. Its complete offline maps of the globe can seamlessly direct you back to the path if you get lost without a phone, and look excellent on the large, crisp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the more compact 43mm size 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 despite the screen on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and satellite service plan instead of relying on a watch plan tied to your phone provider, as with other smartwatches. However unlike competing satellite-enabled products, SOS messaging is not included for no cost.

Rather, plans begin from £7.99 or equivalent a month, which includes unlimited LTE text and audio messages, call functionality and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while out jogging, biking or similar pursuits – along with SOS orbital SOS messaging.

Check-ins and texts via orbital are then charged additionally, with higher-tier subscriptions including different allowances of satellite use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have got it set up, you just head out outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you can place and receive calls, send texts and generally keep in touch with your relatives and friends.

When you message someone, Garmin dispatches them an SMS from a random 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 spoken communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to register 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 customisable pre-set replies you can send to speed things up. Voice messages and calls work acceptably, although as with the majority of wearables, you’re unlikely going to wish to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically transmit a URL to chosen contacts whenever you begin an exercise, so they can follow your real time location on a map. It’s excellent for following competition 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 effectively, though the actual position has sometimes lagged when transitioning in and out of good LTE signal.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is important to remember that orbital coverage is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with options available through the customer service site. The battery is rated to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused materials. Garmin provides recycling 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 subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re out of coverage.

Outcome is an even more remarkable outdoor device for those that desire to be phone-free. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

It is quite liberating to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone provider so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, biking or trekking, but still wants to be trackable and contactable. For other users, it is a significant expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely costly, LTE and satellite functions require monthly payment, limited Garmin Pay bank compatibility, voice features are slow, limited wearable functionality versus competing watches.
