Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Texting

This newest iteration of Garmin's top-tier Fenix adventure watch introduces a life-saving feature: phone-free communication and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge mobile technology, plus an optional advanced microLED display in a special edition. It is Garmin's premier device and engineered to be the single tool required to venture almost any location and monitor every activity.

This positions it as an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the price of the regular Fenix 8.

Users get a lot of features for your investment, with industry-leading workout, movement and outdoor tracking. Its full offline mapping of the globe can automatically guide you back to the trail if you lose your way absent a phone, and appear excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as tested does have an extra day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your mobile carrier, as with other wearables. But in contrast to competing satellite-enabled products, SOS communication is not provided for free.

Instead, plans begin from £7.99 or equivalent a month, which provides unlimited LTE text and audio messages, call functionality and LiveTrack position sharing – so your friends or loved ones can monitor you while engaged in running, biking or comparable pursuits – along with SOS satellite SOS alerts.

Check-ins and messages via satellite are then billed on top, with more expensive plans including different quotas of orbital usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the service.

After you have got it set up, you simply head out outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you are able to make and take calls, send texts and overall stay connected with your family and friends.

Whenever you text someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally via text or spoken communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a phone number is enough to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable canned replies you can use to speed things up. Spoken recordings 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 audio clarity is less than ideal.

LiveTrack is the most useful feature. You can set it up to automatically transmit a URL to chosen contacts every time you start an exercise, so they can track your live location on a map. It’s excellent for monitoring race progress, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has typically worked effectively, although the actual position has occasionally lagged when transitioning in and out of good LTE coverage.

All of these features are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A guide shows you how to locate the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is essential to note that orbital service is restricted to the US continent, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with services available through the support portal. The battery is certified to retain at least 90% of its original capacity after two years of regular charging. The watch lacks any recycled materials. 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 packages 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, calls and LiveTrack – along with orbital communication, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that desire to be unplugged. 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 requiring additional gear.

It is very liberating to be outside without a phone, but that capability carries quite a cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the features. At least it is not reliant on your phone carrier so functions with any brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless wants to be trackable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with premier GPS, built-in flashlight, voice and standalone commands, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and satellite features need monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, limited wearable features versus Apple/Google/Samsung watches.
