Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

The most recent iteration of the flagship Fenix outdoor timepiece introduces a life-saving capability: phone-free messaging and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular tech, along with an optional state-of-the-art microLED screen in a limited edition. It is Garmin's premier device and designed to be the single gadget required to explore almost anywhere and monitor all your movements.

That positions it as an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the price of the standard Fenix 8.

Users receive a lot of functionality for your money, with best-in-class fitness, movement and adventure monitoring. Its complete offline mapping of the globe can automatically direct you back to the trail if you lose your way absent a phone, and appear excellent on the large, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed does have an additional day of smartwatch battery life despite the display always active, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

The company uses its own inReach LTE (4G) and orbital service service instead of relying on a watch plan linked to your mobile carrier, like other wearables. But unlike competing satellite-enabled products, SOS communication is not provided for free.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE text and audio messages, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while engaged in running, cycling or comparable activities – plus SOS orbital SOS messaging.

Location updates and texts over satellite are then charged on top, with more expensive subscriptions including various quotas of orbital usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the functionality.

After you have completed setup, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you are able to place and receive calls, send texts and overall keep in touch with your relatives and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via typed or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a phone number is enough to register for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It includes a set of customisable canned replies you can send to expedite communication. Voice recordings and calls perform acceptably, though as with most smartwatches, you’re not going to wish to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest function. You can set it up to on its own send a link to selected contacts every time you start an activity, so they can follow your real time position on a map. It’s excellent for following race performance, but it mostly acts as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally worked effectively, although the real position has sometimes been delayed 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 lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A guide displays you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, though it is important to note that orbital service is restricted to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with services available through the support portal. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin offers disposal programs on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an increasingly impressive adventure device for those that want 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 does so without requiring additional gear.

This is quite liberating to be outside without a phone, but that functionality carries quite a price, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to enable the service. At least it isn’t reliant on your phone carrier so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and satellite communication, high-luminance OLED screen, tracks all activities with premier GPS, integrated torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and satellite features require ongoing payment, restricted Garmin Pay financial compatibility, speech capabilities are slow, limited wearable features versus Apple/Google/Samsung watches.
