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

This most recent version of the top-tier Fenix adventure timepiece includes a potentially lifesaving capability: no-phone messaging and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new cellular tech, plus an optional state-of-the-art microLED screen in a limited edition. It is the brand's top device and engineered to be the single tool required to venture almost anywhere and monitor every activity.

This positions it as an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the price of the regular Fenix 8.

You do receive a lot of functionality for your investment, with industry-leading workout, activity and adventure monitoring. The full offline maps of the globe can automatically direct you back to the trail if you lose your way without a phone, and look excellent on the sizable, crisp and high-luminance touchscreen.

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

Phone-Free Messaging, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and orbital service plan instead of relying on a watch plan linked to your phone carrier, like other smartwatches. However in contrast to Apple or Google's satellite-capable devices, emergency messaging is not provided for free.

Instead, subscriptions start at £7.99 or similar a month, which provides limitless LTE SMS and voice messaging, calls and LiveTrack location sharing – so your friends or family can monitor you while engaged in running, biking or similar pursuits – plus SOS satellite SOS alerts.

Location updates and messages via orbital are then charged additionally, with more expensive plans including different allowances of satellite use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can test out the service.

After you have got it set up, you simply venture the door minus your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you can place and receive calls, dispatch texts and overall stay connected with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using typed or spoken messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a mobile number is enough to sign up for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of customisable pre-set responses you can use to expedite communication. Voice recordings and calls perform acceptably, although as with most wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can configure to automatically send a link to selected contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for monitoring competition progress, but it mostly acts as a utility for someone you trust to know your location in case something happens. It has typically functioned well, although the actual position has sometimes been delayed when moving in and out of good LTE coverage.

All of these capabilities are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A guide displays you how to locate the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is important to remember that satellite service is limited to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available through the customer service portal. The battery is rated to retain at least 90% of its original power after two years of regular charging. The watch does not contain any reused components. Garmin offers disposal programs on new 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 packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re out of coverage.

Outcome is an increasingly remarkable adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to enable the features. Fortunately it is not dependent on your phone carrier so works with any brand of smartphone and network.

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

Advantages: LTE and orbital messaging, high-luminance OLED screen, tracks all activities with premier GPS, built-in torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

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