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

This most recent iteration of the flagship Fenix adventure watch introduces a life-saving capability: phone-free communication and SOS alerts via 4G LTE or orbital links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new mobile tech, plus an available advanced microLED screen in a limited edition. This is the brand's premier device and designed to be the only tool needed to venture almost anywhere and track every activity.

This positions it as an very pricey proposition, starting at £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 variant with microLED screen – nearly twice the price of the standard Fenix 8.

You do receive a lot of features for your investment, with best-in-class fitness, activity and outdoor monitoring. Its complete offline mapping of the globe can automatically direct you return to the trail if you lose your way without a phone, and look great on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan linked to your phone provider, like other smartwatches. But unlike Apple or Google's satellite-enabled products, emergency messaging is not included for no cost.

Instead, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE text and voice messaging, call functionality and LiveTrack location tracking – so your friends or family can monitor you while engaged in jogging, biking or similar activities – plus SOS satellite SOS messaging.

Check-ins and messages via orbital are then charged on top, with higher-tier subscriptions including different quotas of orbital usage, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you simply head out the door without your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and overall keep in touch with your family and companions.

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

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of customisable canned responses you can send to speed things up. Voice recordings and calls work acceptably, although as with most wearables, you’re not going to wish to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to on its own send a link to selected contacts whenever you begin an exercise, so they can follow your live position on a map. It’s great for following race progress, but it mostly serves as a tool for someone you rely on to be aware of your location in case an incident occurs. It has typically functioned well, though the actual location has occasionally lagged when transitioning in and out of strong LTE signal.

All of these features are accessible 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 transmit texts, position check-ins and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, though it is important to remember that orbital coverage is limited to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally repairable with services offered through the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled materials. Garmin offers recycling programs on new 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 plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

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

The result is an even more impressive outdoor tool for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is quite liberating to be outdoors without a phone, but that capability comes at quite a price, both in terms of the colossal price of the watch and the monthly fee of the inReach service to enable the service. Fortunately it isn’t reliant on your phone carrier so works with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED display, tracks everything with premier GPS, built-in flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and satellite features require ongoing subscription, restricted Garmin Pay financial support, voice capabilities are slow, limited wearable features versus Apple/Google/Samsung watches.
