The Fenix 8 Pro Review: Integrated LTE and Satellite Communication for Phone-Free Messaging

This newest model of Garmin's flagship Fenix adventure timepiece includes a potentially lifesaving capability: no-phone messaging and SOS alerts via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by adding cutting-edge cellular technology, plus an optional advanced microLED display in a special edition. This is the brand's premier model and designed to be the single gadget required to explore virtually any location and monitor every activity.

That makes it an extremely expensive option, priced from £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 edition with microLED display – almost twice the cost of the regular Fenix 8.

You do receive a significant features for your money, with best-in-class workout, activity and adventure monitoring. Its full offline maps of the world can seamlessly guide you return to the trail if you lose your way absent a phone, and appear excellent on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other models, so it is a big watch for bigger wrists. But the 47mm OLED model 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, Calling and Live Tracking

The company operates its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan linked to your mobile carrier, as with other wearables. But in contrast to competing satellite-enabled devices, SOS messaging is not included for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and audio messages, calls and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while out jogging, cycling or comparable pursuits – plus SOS satellite SOS alerts.

Location updates and messages over satellite are then billed additionally, with more expensive subscriptions including different quotas of satellite use, increasing to a £50 a month unlimited plan. 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 outside without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you are able to make and take calls, send texts and overall stay connected with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install 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 profile to use the Messenger app, only a phone number is enough to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of personalizable canned responses you can use to expedite communication. Voice recordings and calls work OK, although as with the majority of wearables, you’re not going to want to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can configure to automatically send a URL to selected contacts every time you begin an activity, so they can follow your real time location on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you rely on to know your location in case something happens. It has typically worked well, though the actual location has occasionally been delayed when moving in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to remember that satellite service is restricted to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with options available via the customer service site. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin offers 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 service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor tool for those that desire to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

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

This Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, biking or hiking, but still desires to be locatable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED display, tracks everything with best-in-class GPS, integrated torch, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: extremely costly, LTE and orbital functions require monthly payment, limited Garmin Pay financial support, speech features are sluggish, limited wearable features versus Apple/Google/Samsung watches.
