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

This most recent iteration of the premium Fenix outdoor timepiece introduces a life-saving capability: phone-free messaging and emergency alerts using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular tech, along with an optional advanced microLED display in a limited edition. It is Garmin's top device and engineered to be the single tool needed to explore virtually any location and monitor every activity.

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

You do receive a significant functionality for your investment, with industry-leading fitness, movement and adventure tracking. The full offline mapping of the globe can automatically direct you return to the path if you get lost absent a phone, and appear great on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life despite the display always active, lasting a solid eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan tied to your phone carrier, like other smartwatches. But unlike Apple or Google's satellite-capable products, emergency messaging is not provided for free.

Instead, subscriptions start at £7.99 or similar a month, which includes limitless LTE SMS and voice messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can keep an eye on you while engaged in jogging, biking or comparable pursuits – plus SOS orbital SOS messaging.

Check-ins and texts via orbital are then charged on top, with higher-tier plans including various quotas of satellite use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have completed setup, you simply head out the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, dispatch texts and overall stay connected with your family and friends.

When 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 reciprocally using typed or voice communications, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a mobile number is enough to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable canned replies you can send to expedite communication. Voice recordings and calls perform acceptably, although as with most smartwatches, you’re unlikely going to wish to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to selected contacts whenever you start an exercise, so they can follow your live location on a map. It’s excellent for monitoring competition progress, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned effectively, though the real location has sometimes lagged when transitioning in and out of strong LTE coverage.

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

A guide displays you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to note that orbital service is limited to the US continent, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered through the customer service site. The battery is certified to retain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled materials. Garmin provides disposal schemes on new purchases.

Price

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite messaging, check-in and SOS SOS for when you’re without signal.

The result is an increasingly remarkable outdoor device for those that want to be unplugged. If you want to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

This is quite freeing to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to enable the features. Fortunately it isn’t dependent on your phone carrier so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but still desires to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors everything with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and orbital features need ongoing payment, limited Garmin Pay bank compatibility, voice features are slow, basic smartwatch features versus Apple/Google/Samsung watches.
