The Fenix 8 Pro Analysis: Integrated LTE and Orbital Communication for No-Phone Messaging

This latest version of Garmin's flagship Fenix outdoor timepiece introduces a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new cellular technology, along with an optional state-of-the-art microLED screen in a limited edition. It is Garmin's premier device and designed to be the only tool required to venture almost any location and track every activity.

This makes it an extremely expensive proposition, starting at £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 variant with microLED display – almost double the cost of the standard Fenix 8.

Users get a significant functionality for your money, with industry-leading fitness, movement and outdoor monitoring. The full offline maps of the world can automatically direct you return to the path if you lose your way without a phone, and look great on the sizable, crisp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as tested boasts an additional day of smartwatch battery life even with the screen on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital service plan instead of relying on a watch plan tied to your mobile carrier, like other wearables. But unlike Apple or Google's satellite-enabled devices, emergency messaging is not provided for no cost.

Instead, plans start at £7.99 or similar a month, which includes limitless LTE text and audio messages, call functionality and LiveTrack location tracking – so your contacts or family can monitor you while engaged in jogging, cycling or similar activities – plus emergency orbital SOS messaging.

Location updates and texts via satellite are then charged on top, with higher-tier subscriptions offering different quotas of orbital use, climbing 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 just head out outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you are able to make and take calls, dispatch texts and generally stay connected with your family and companions.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a phone number is sufficient to register for texts.

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable canned responses you can use to speed things up. Spoken messages and calls work OK, though as with the majority of wearables, you’re not going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a URL to chosen contacts every time you begin an activity, so they can follow your real time position on a map. It’s excellent for monitoring competition performance, but it primarily serves as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally worked well, although the actual position has sometimes lagged when transitioning in and out of strong LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to note that satellite coverage is limited to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available through the support portal. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled components. Garmin provides disposal schemes on recent 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

The Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an even more remarkable adventure tool for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin does so without needing anything else.

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

The Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks everything with best-in-class GPS, built-in torch, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: very expensive, LTE and orbital functions need monthly payment, restricted Garmin Pay financial support, voice capabilities are sluggish, basic smartwatch features versus competing watches.
