The Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for Phone-Free Messaging

The most recent version of the premium Fenix outdoor timepiece introduces a potentially lifesaving feature: phone-free communication and SOS messaging via 4G LTE or orbital links.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile technology, along with an available state-of-the-art microLED display in a limited edition. It is Garmin's top model and engineered to be the only gadget required to venture almost any location and monitor every activity.

This makes it an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the cost of the regular Fenix 8.

You do receive a lot of functionality for your investment, with best-in-class fitness, movement and outdoor monitoring. The full offline maps of the world can automatically guide you return to the trail if you get lost without a phone, and appear great on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm size found 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 display always active, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Real-Time Location

The company operates its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan tied to your phone carrier, like other smartwatches. However unlike competing satellite-capable devices, SOS communication is not included for free.

Rather, subscriptions start at £7.99 or equivalent a month, which provides limitless LTE text and voice messaging, calls and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while out jogging, cycling or similar pursuits – along with SOS satellite SOS alerts.

Check-ins and messages over orbital are then billed additionally, with more expensive plans offering various quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the service.

After you have completed setup, you just head out the door without your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, dispatch texts and overall keep in touch with your family and companions.

Whenever 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 application, you can then communicate back and forth via text or spoken messages, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a mobile number is enough to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It has a set of personalizable pre-set replies you can send to speed things up. Spoken messages and calls work OK, though as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can set it up to automatically send a URL to selected contacts whenever you start an exercise, so they can track your real time position on a map. It’s excellent for monitoring competition performance, but it mostly serves as a utility for someone you rely on to know your location in case something happens. It has typically functioned well, though the real location has sometimes lagged when moving in and out of good LTE signal.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide 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 unexpectedly straightforward to use and could be a vital safety feature, though it is essential to note that satellite service is restricted to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with options offered through the support site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin provides disposal programs on recent purchases.

Price

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 excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly remarkable adventure device for those that desire to be unplugged. If you wish to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

It is quite liberating to be outside without a phone, but that capability comes at a significant price, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it isn’t reliant on your phone carrier so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED display, monitors all activities with best-in-class GPS, integrated flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.
