Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for Phone-Free Messaging

The newest version of Garmin's top-tier Fenix adventure watch includes a life-saving capability: phone-free communication and emergency messaging using 4G LTE or satellite connections.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by adding new cellular technology, along with an available advanced microLED display in a special edition. It is the brand's premier model and designed to be the only tool needed to explore almost any location and monitor all your movements.

This makes it an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the price of the regular Fenix 8.

You do get a lot of functionality for your money, with best-in-class fitness, activity and adventure tracking. Its full offline maps of the globe can seamlessly guide you return to the path if you get lost without a phone, and appear excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other models, so it is a large watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of watch battery life even with the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than depending on a watch plan linked to your phone provider, like other smartwatches. However unlike competing satellite-capable products, SOS communication is not provided for no cost.

Rather, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and voice messages, calls and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while out running, biking or similar activities – plus SOS orbital SOS messaging.

Check-ins and messages over satellite are then charged on top, with higher-tier plans offering various allowances of orbital usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you just head out the door without 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 generally stay connected with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then message 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 mobile number is sufficient to sign up for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is slow. It has a collection of personalizable canned replies you can use to speed things up. Voice recordings and calls work acceptably, though as with most wearables, you’re not going to want to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to on its own transmit 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 following competition progress, but it mostly serves as a utility for someone you rely on to know your whereabouts in case something happens. It has typically worked effectively, although the real position has occasionally been delayed when moving in and out of strong LTE signal.

These features are available on other Garmin watches 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 check-ins and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is important to remember that orbital service is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available through the customer service portal. The battery is certified to retain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin offers disposal programs on new purchases.

Cost

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

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of signal.

The result is an increasingly remarkable adventure tool for those that want to be phone-free. 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 does so without needing additional gear.

It is quite liberating to be outdoors without a phone, but that functionality carries quite a price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to enable the features. Fortunately it isn’t dependent on your phone carrier so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, cycling or hiking, but nevertheless desires to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, voice and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Drawbacks: extremely expensive, LTE and orbital functions require monthly payment, restricted Garmin Pay bank compatibility, voice features are sluggish, basic wearable functionality compared with competing watches.
