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

The most recent iteration of the premium Fenix adventure watch brings a life-saving feature: no-phone messaging and SOS messaging via 4G LTE or satellite connections.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating new cellular tech, along with an optional state-of-the-art microLED screen in a special edition. This is Garmin's top model and designed to be the only gadget needed to explore virtually anywhere and track every activity.

This makes it an very pricey option, starting at £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 edition with microLED screen – almost twice the cost of the standard Fenix 8.

You do receive a significant functionality for your investment, with best-in-class workout, movement and outdoor monitoring. The complete offline mapping of the world can seamlessly guide you back to the path if you get lost absent a phone, and appear great on the large, sharp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan linked to your mobile provider, like other wearables. But in contrast to competing satellite-enabled devices, emergency messaging is not included for free.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messaging, calls and LiveTrack location tracking – so your friends or loved ones can monitor you while out running, cycling or similar activities – plus emergency orbital SOS alerts.

Check-ins and texts over satellite are then charged additionally, with more expensive subscriptions including various quotas of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you simply venture the door without your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you can place and receive calls, dispatch texts and overall keep in touch with your relatives and companions.

When 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 application, you can then message back and forth using typed or voice messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a mobile number is enough to sign up for texts.

Messaging on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable canned replies you can send to expedite communication. Spoken recordings and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for extended conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to automatically send a link to selected contacts every time you begin an activity, so they can follow your real time position on a map. It’s great for monitoring race performance, but it primarily serves as a tool for someone you rely on to know your location in case an incident occurs. It has typically functioned effectively, although the real location has sometimes been delayed when transitioning in and out of strong LTE signal.

All of these capabilities 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 emergency SOS.

A guide shows you how to find the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, though it is important to remember that orbital coverage is limited to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with services available via the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch does not contain any reused materials. Garmin provides recycling programs on new purchases.

Cost

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

Verdict

The Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re out of coverage.

The result is an even more remarkable adventure tool for those that want to be unplugged. If you want to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite liberating to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to provide the features. Fortunately it isn’t reliant on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or hiking, but nevertheless wants to be locatable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED screen, monitors everything with best-in-class GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very costly, LTE and satellite features require ongoing subscription, limited Garmin Pay bank compatibility, voice features are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
