Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Texting

This latest model of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving capability: phone-free communication and SOS alerts using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding cutting-edge cellular technology, plus an available advanced microLED screen in a special edition. This is the brand's premier device and designed to be the single tool needed to venture virtually anywhere and monitor all your movements.

This makes it an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the price of the regular Fenix 8.

You do receive a significant features for your money, with industry-leading workout, movement and adventure monitoring. The complete offline maps of the world can seamlessly direct you return to the path if you lose your way absent a phone, and look excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as tested does have an extra day of watch battery life despite the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital service service instead of relying on a watch plan tied to your phone carrier, like other smartwatches. However in contrast to competing satellite-enabled products, emergency messaging is not provided for no cost.

Instead, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack position tracking – so your contacts or family can keep an eye on you while out running, biking or comparable activities – along with emergency orbital SOS alerts.

Location updates and messages via satellite are then charged on top, with more expensive subscriptions offering different quotas of orbital use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

After you have got it set up, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, dispatch texts and generally keep in touch with your family and companions.

When you message someone, Garmin dispatches 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 communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a phone number is enough to sign up for texts.

Texting on the watch functions fine but composing texts on the small on-screen keyboard is slow. It has a set of personalizable canned replies you can send to speed things up. Spoken recordings and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is less than fantastic.

LiveTrack is the most useful feature. You can configure to automatically transmit a link to selected contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for monitoring race performance, but it mostly serves as a tool for someone you trust to know your location in case something happens. It has typically worked well, although the real location has occasionally lagged when moving in and out of strong LTE signal.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to note that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically serviceable with services offered via the support portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin offers disposal programs on recent purchases.

Cost

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

Conclusion

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor device for those that want to be unplugged. If you wish to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without needing anything else.

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

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or trekking, but still wants to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks all activities with best-in-class GPS, integrated torch, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and orbital functions need monthly payment, restricted Garmin Pay bank compatibility, voice capabilities are slow, limited wearable functionality compared with competing watches.
