Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for No-Phone Messaging

The most recent iteration of the flagship Fenix outdoor timepiece includes a life-saving capability: no-phone communication and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge cellular tech, plus an available advanced microLED screen in a limited edition. This is the brand's top model and engineered to be the only tool needed to explore almost anywhere and track all your movements.

That positions it as an extremely pricey proposition, priced from £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 variant with microLED display – nearly twice the cost of the standard Fenix 8.

You do receive a significant features for your money, with best-in-class workout, movement and adventure tracking. The complete offline mapping of the world can automatically direct you back to the path if you lose your way without a phone, and look great on the sizable, crisp and high-luminance display.

The 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 larger wrists. However the 47mm OLED version as tested does have an extra day of watch battery life even with the screen always active, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service plan instead of depending on a watch plan linked to your phone provider, as with other wearables. But unlike competing satellite-capable products, SOS communication is not included for free.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack location tracking – so your contacts or family can monitor you while engaged in running, biking or comparable pursuits – along with emergency orbital SOS alerts.

Check-ins and texts over satellite are then billed on top, with more expensive plans offering different quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you just venture outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using text or spoken messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, just a mobile number is sufficient to register for texts.

Texting on the watch works adequately but typing out texts on the tiny on-screen keyboard is slow. It has a set of customisable pre-set replies you can send to expedite communication. Voice messages and calls perform acceptably, although as with most smartwatches, you’re not going to want to use it for extended discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can set it up to automatically send a link to chosen contacts every time you start an exercise, so they can track your live location on a map. It’s great for following race progress, but it mostly serves as a utility for someone you trust to know your location in case something happens. It has typically worked effectively, though the actual position has occasionally been delayed when moving in and out of strong LTE signal.

All of these features are available on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide displays you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, however it is important to remember that satellite coverage is restricted to the US continent, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with options offered through the customer service portal. The battery is rated to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin offers recycling schemes on recent purchases.

Price

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

Conclusion

The 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 orbital communication, check-in and SOS SOS for when you’re out of coverage.

The result is an even more remarkable adventure tool for those that desire to be phone-free. 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 additional gear.

It is very liberating to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the service. Fortunately it is not reliant on your phone carrier so functions with all make of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who dislikes being burdened by their phone when jogging, biking or hiking, but still wants to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED screen, monitors everything with best-in-class GPS, integrated torch, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: extremely expensive, LTE and satellite features need ongoing payment, limited Garmin Pay bank compatibility, speech capabilities are sluggish, limited wearable features compared with Apple/Google/Samsung watches.
