The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

The newest model of Garmin's top-tier Fenix adventure timepiece introduces a potentially lifesaving capability: phone-free messaging and SOS messaging using 4G LTE or satellite links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating cutting-edge cellular tech, along with an optional advanced microLED display in a special edition. It is Garmin's premier device and engineered to be the single gadget required to explore virtually anywhere and track all your movements.

This positions it as an extremely pricey option, priced from £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 – almost double the cost of the standard Fenix 8.

Users receive a lot of features for your investment, with industry-leading fitness, activity and outdoor monitoring. Its complete offline mapping of the world can seamlessly direct you back to the trail if you lose your way without a phone, and look great on the sizable, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of smartwatch battery life even with the screen always active, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital service service rather than relying on a watch plan linked to your phone carrier, like other wearables. But unlike competing satellite-enabled devices, SOS messaging is not provided for no cost.

Rather, plans begin from £7.99 or similar a month, which provides limitless LTE SMS and audio messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in running, biking or similar pursuits – along with SOS orbital SOS alerts.

Location updates and messages over satellite are then billed on top, with more expensive subscriptions offering different allowances of satellite usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

After you have got it set up, you just head out the door without your phone and the watch will link to LTE. You can not use it for playing music or comparable activities, but you are able to make and take calls, dispatch texts and overall stay connected with your family and friends.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, just a phone number is enough to register for texts.

Texting on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable pre-set responses you can use to speed things up. Voice messages and calls perform acceptably, though as with most smartwatches, you’re not going to wish to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to selected contacts whenever you begin an exercise, so they can track your real time location on a map. It’s great for following race progress, but it mostly serves as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has typically worked well, although the actual location has occasionally been delayed 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 areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the satellite, which then sends and receives 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 remember that satellite coverage is restricted to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services offered via the customer service site. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any reused components. Garmin provides recycling programs on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you wish to have someone monitor you from afar while running after dark or in the remote areas, the Garmin does so without requiring additional gear.

It is quite freeing to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach service to enable the features. At least it is not dependent on your phone provider so functions with any make of smartphone and carrier.

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

Pros: LTE and orbital communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very costly, LTE and orbital functions need ongoing payment, restricted Garmin Pay bank support, voice features are sluggish, limited wearable functionality compared with competing watches.
