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

This latest version of the premium Fenix outdoor timepiece includes a life-saving capability: no-phone messaging and emergency messaging via 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by adding cutting-edge mobile tech, along with an optional state-of-the-art microLED screen in a limited edition. This is the brand's top device and engineered to be the only gadget needed to explore virtually anywhere and track every activity.

That makes it an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the regular Fenix 8.

You do get a lot of features for your money, with best-in-class fitness, activity and outdoor monitoring. The full offline maps of the globe can automatically direct you back to the trail if you get lost absent a phone, and appear excellent on the large, crisp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the smaller 43mm version found in other models, so it is a big watch for larger wrists. However the 47mm OLED version as reviewed does have an extra day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite subscription service rather than relying on a watch plan tied to your mobile provider, like other smartwatches. But in contrast to Apple or Google's satellite-capable products, emergency messaging is not provided for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or comparable activities – along with SOS orbital SOS messaging.

Location updates and messages via satellite are then charged on top, with higher-tier plans offering different quotas of satellite use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can evaluate the service.

After you have completed setup, you just venture outside without your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, dispatch texts and generally stay connected with your relatives and companions.

When you text someone, Garmin dispatches them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth using typed or spoken messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is enough to register for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can use to expedite communication. Spoken recordings and calls perform acceptably, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful function. You can set it up to automatically send a URL to selected contacts whenever you begin an activity, so they can track your live location on a map. It’s great for monitoring 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 typically functioned effectively, although the actual location has occasionally lagged when transitioning in and out of strong LTE coverage.

All of these features are available on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency 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 surprisingly straightforward to use and could be a vital lifeline, however it is essential to remember that satellite service is limited to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with options available via the customer service site. The battery is rated to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused materials. Garmin offers disposal programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, location update and emergency 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 keep an eye on you from afar while running out at night or in the remote areas, the Garmin does so without requiring anything else.

It is quite liberating to be outside without a phone, but that functionality comes at a significant price, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to provide the service. At least it is not reliant on your phone carrier so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks everything with best-in-class GPS, integrated flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital functions need ongoing subscription, limited Garmin Pay bank support, voice features are sluggish, limited smartwatch features compared with Apple/Google/Samsung watches.
