Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Texting

The most recent version of the flagship Fenix adventure watch introduces a life-saving feature: phone-free messaging and SOS messaging using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge mobile technology, plus an available advanced microLED screen in a limited edition. This is the brand's premier device and designed to be the single gadget required to explore virtually anywhere and track all your movements.

This positions it as an very pricey option, starting at £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 display – nearly twice the cost of the regular Fenix 8.

Users receive a lot of features for your money, with best-in-class fitness, movement and outdoor tracking. The complete offline mapping of the world can seamlessly direct you return to the trail if you lose your way without a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm version available in other models, so it is a big watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of smartwatch battery life despite the display on all the time, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription service rather than depending on a watch plan linked to your mobile provider, like other wearables. But unlike competing satellite-enabled products, SOS messaging is not provided for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE SMS and audio messaging, call functionality and LiveTrack location tracking – so your contacts or family can monitor you while engaged in jogging, cycling or comparable activities – plus SOS satellite SOS alerts.

Check-ins and texts over satellite are then billed additionally, with more expensive plans including various allowances of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

Once 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 activities, but you can make and take calls, dispatch texts and generally stay connected with your family and companions.

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

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable pre-set replies you can use to speed things up. Spoken recordings and calls perform OK, although as with most smartwatches, you’re not going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to on its own transmit a link to selected contacts whenever you start an exercise, so they can follow your live position on a map. It’s excellent for monitoring race performance, but it mostly serves as a tool for someone you trust to know your whereabouts in case an incident occurs. It has typically functioned well, although the actual location has sometimes been delayed when transitioning in and out of good LTE signal.

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

A guide displays you how to find the line of sight 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 important to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered via the customer service portal. 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 reused components. Garmin offers disposal programs on recent 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 packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor tool for those that desire to be phone-free. If you wish to have someone monitor you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is quite freeing to be outside without a phone, but that capability comes at a significant price, both in terms of the colossal price of the watch and the recurring fee of the inReach plan to provide the service. Fortunately it is not reliant on your phone provider so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, biking or hiking, but nevertheless wants to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED screen, tracks all activities with premier GPS, built-in flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: extremely costly, LTE and satellite features need monthly payment, restricted Garmin Pay financial compatibility, speech features are sluggish, limited wearable features compared with competing watches.
