The Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for No-Phone Texting

The latest model of the premium Fenix adventure watch brings a potentially lifesaving feature: phone-free messaging and emergency alerts via 4G LTE or satellite links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular tech, plus an available state-of-the-art microLED screen in a limited edition. This is the brand's premier device and engineered to be the only gadget required to explore virtually any location and monitor all your movements.

That positions it as an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to 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 functionality for your money, with industry-leading fitness, movement and outdoor tracking. The full offline mapping of the world can seamlessly direct you back to the trail if you get lost without a phone, and appear great on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of watch battery life even with the display always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan tied to your mobile carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled products, SOS communication is not included for free.

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and voice messages, call functionality and LiveTrack position tracking – so your contacts or family can monitor you while engaged in jogging, cycling or similar activities – plus emergency orbital SOS alerts.

Check-ins and messages over satellite are then charged on top, with more expensive plans offering different quotas of satellite use, increasing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply head out the door minus your phone and the watch will link 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 stay connected with your family 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 app, you can then message reciprocally via typed or spoken messages, and make voice calls. Your recipient does not need a Garmin account 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 includes a collection of customisable canned replies you can send to expedite communication. Spoken recordings and calls work acceptably, though as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is not fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a link to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s great for following race progress, but it primarily serves as a tool for someone you trust to know your whereabouts in case something happens. It has generally functioned effectively, although the real position has sometimes lagged when moving in and out of strong LTE signal.

These features are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, though it is important to remember that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with services offered via the support site. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any recycled components. Garmin offers recycling schemes on new purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

It is quite liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to provide the service. Fortunately it is not reliant on your phone carrier so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, biking or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED display, tracks everything with best-in-class GPS, built-in flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and orbital features require monthly payment, restricted Garmin Pay bank compatibility, voice features are sluggish, basic wearable functionality compared with Apple/Google/Samsung watches.
