The Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Messaging

This latest version of Garmin's premium Fenix outdoor watch introduces a life-saving capability: no-phone messaging and SOS messaging via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating cutting-edge mobile tech, plus an available state-of-the-art microLED screen in a special edition. This is Garmin's top device and engineered to be the single tool needed to explore virtually anywhere and monitor all your movements.

That positions it as an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the price of the regular Fenix 8.

Users get a lot of features for your investment, with best-in-class fitness, activity and adventure tracking. The full offline mapping of the world can seamlessly guide you back to the trail if you lose your way without a phone, and appear excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan tied to your phone provider, as with other smartwatches. However unlike Apple or Google's satellite-capable products, SOS communication is not provided for no cost.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE text and audio messaging, calls and LiveTrack location sharing – so your contacts or family can keep an eye on you while engaged in jogging, cycling or comparable pursuits – along with SOS satellite SOS alerts.

Check-ins and messages via satellite are then charged additionally, with more expensive plans including different allowances of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the service.

Once you have completed setup, you just head out outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable activities, but you can place and receive calls, dispatch texts and overall stay connected with your relatives and companions.

When you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth via typed or spoken messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable canned replies you can send to speed things up. Spoken messages and calls perform acceptably, although as with most smartwatches, you’re not going to wish to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest function. You can configure to automatically send a URL to selected contacts every time you begin an activity, so they can track 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 location has sometimes been delayed when moving in and out of good LTE coverage.

All of these features are available on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, though it is important to note that orbital service is restricted to the US mainland, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with options available via the support site. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal schemes on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital communication, 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 phone-free. If you wish to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is quite liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to provide the features. At least it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless wants to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED screen, monitors everything with best-in-class GPS, integrated torch, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: extremely costly, LTE and orbital functions require monthly subscription, limited Garmin Pay bank support, speech features are sluggish, basic smartwatch functionality versus Apple/Google/Samsung watches.
