Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Communication for No-Phone Messaging

This most recent model of the premium Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new cellular tech, along with an available advanced microLED display in a limited edition. This is Garmin's top model and engineered to be the single gadget required to venture almost any location and monitor every activity.

This positions it as an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the price of the regular Fenix 8.

You do receive a lot of features for your investment, with best-in-class fitness, movement and outdoor tracking. Its full offline mapping of the globe can automatically guide you return to the trail if you lose your way without a phone, and appear great on the large, crisp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not 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 display always active, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and satellite service plan instead of relying on a watch plan linked to your phone carrier, as with other wearables. However unlike competing satellite-enabled devices, SOS messaging is not included for no cost.

Instead, plans begin from £7.99 or similar a month, which includes limitless LTE text and audio messaging, calls and LiveTrack position sharing – so your friends or loved ones can monitor you while engaged in running, biking or comparable pursuits – plus emergency orbital SOS messaging.

Check-ins and texts over satellite are then billed on top, with higher-tier subscriptions offering different quotas of orbital use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have completed setup, you just head out the door minus your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and generally stay connected with your relatives and companions.

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

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable canned responses you can use to expedite communication. Voice recordings and calls perform acceptably, though as with the majority of wearables, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can configure to automatically send a URL to selected contacts every time you begin an exercise, so they can track your real time location on a map. It’s great for following competition performance, but it primarily serves as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally functioned effectively, although the real location has sometimes lagged when transitioning in and out of good LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide 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 surprisingly easy to use and could be a crucial lifeline, however it is essential to remember that orbital service is limited to the US continent, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options offered via the support site. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal programs on new purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite communication, check-in and emergency SOS for when you’re out of coverage.

The result is an even more remarkable adventure device for those that want to be phone-free. If you wish to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is very liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the colossal price of the watch and the monthly fee of the inReach service to enable the features. At least it is not dependent on your phone carrier so works with all brand of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, biking or trekking, but still wants to be trackable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, high-luminance OLED display, tracks everything with premier GPS, integrated torch, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital functions require monthly subscription, restricted Garmin Pay financial support, speech features are sluggish, basic wearable features versus competing watches.
