The Fenix 8 Pro Analysis: Integrated LTE and Orbital Connectivity for No-Phone Messaging

This most recent model of the flagship Fenix outdoor timepiece brings a potentially lifesaving capability: phone-free communication and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge mobile technology, plus an optional state-of-the-art microLED screen in a special edition. It is Garmin's premier device and engineered to be the single tool needed to venture almost anywhere and track every activity.

This makes it an extremely 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 variant with microLED display – almost double the price of the regular Fenix 8.

Users get a significant functionality for your money, with industry-leading fitness, activity and adventure monitoring. Its full offline maps of the world can automatically guide you return to the trail if you get lost without a phone, and look excellent on the large, sharp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other devices, so it is a large watch for larger wrists. But the 47mm OLED version as tested does have an additional day of watch battery life even with the screen always active, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan tied to your mobile provider, like other wearables. But unlike competing satellite-capable devices, SOS communication is not provided for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while out running, biking or similar activities – along with emergency satellite SOS messaging.

Check-ins and messages via satellite are then billed on top, with more expensive subscriptions including different allowances of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the functionality.

Once you have completed setup, you just head out the door without your phone and the watch will link to LTE. You can not use it for playing music or comparable activities, but you are able to make and take calls, send texts and generally stay connected with your relatives and friends.

When you message someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message back and forth via typed or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Messaging on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It has a collection of personalizable canned responses you can send to expedite communication. Voice messages and calls work acceptably, though as with the majority of wearables, you’re unlikely going to want to use it for extended conversations as the quality is less than ideal.

LiveTrack is the handiest function. You can configure to automatically send a link to selected contacts whenever you start an activity, so they can follow your live position on a map. It’s excellent for monitoring competition progress, but it mostly acts as a tool for someone you trust to know your location in case something happens. It has typically worked effectively, although the actual position has occasionally been delayed when transitioning in and out of good LTE signal.

All of these features are available on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is essential to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered via the support portal. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any recycled components. Garmin provides disposal schemes 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 service plans cost 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 incorporates LTE for texting, call functionality and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more impressive adventure tool for those that desire to be phone-free. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is quite freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the service. At least it is not reliant on your phone carrier so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, cycling or trekking, but nevertheless wants to be trackable and reachable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks everything with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: extremely costly, LTE and satellite functions need ongoing payment, limited Garmin Pay financial compatibility, speech features are sluggish, limited wearable functionality versus Apple/Google/Samsung watches.
