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

This latest model of Garmin's flagship Fenix outdoor timepiece brings a life-saving feature: phone-free communication and emergency alerts using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new mobile technology, along with an available advanced microLED screen in a limited edition. It is the brand's top device and engineered to be the only tool needed to venture almost anywhere and track every activity.

That positions it as an very pricey proposition, starting at £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 – almost double the price of the regular Fenix 8.

Users receive a significant functionality for your investment, with industry-leading workout, movement and outdoor tracking. Its complete offline mapping of the globe can seamlessly guide you back to the trail if you lose your way without a phone, and appear excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other devices, so it is a large watch for larger wrists. But the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the display on all the time, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan linked to your mobile provider, as with other smartwatches. But in contrast to competing satellite-enabled products, SOS messaging is not included for free.

Instead, plans start at £7.99 or similar a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack location tracking – so your friends or family can keep an eye on you while engaged in jogging, biking or similar activities – plus SOS satellite SOS messaging.

Location updates and texts via satellite are then charged on top, with higher-tier plans including various allowances of satellite usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have completed setup, you simply venture outside minus your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and overall keep in touch with your family and companions.

When you message someone, Garmin dispatches 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 message back and forth using typed or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a mobile number is sufficient to register for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of personalizable pre-set replies you can use to expedite communication. Voice recordings and calls work OK, although as with the majority of smartwatches, you’re not going to wish to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the most useful function. You can configure to automatically send a link to chosen contacts every time you start an activity, so they can track your real time location on a map. It’s great for monitoring competition performance, but it mostly acts as a utility for someone you trust to be aware of your location in case something happens. It has generally functioned effectively, though the actual location has sometimes lagged when transitioning in and out of good LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance shows you how to find the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is essential to note that orbital coverage is limited to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available via the customer service portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling schemes on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more impressive adventure device for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while exercising out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

It is quite liberating to be outdoors without a phone, but that capability carries quite a cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to enable the service. Fortunately it is not reliant on your phone carrier so works with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, biking or trekking, but nevertheless wants to be trackable and reachable. For other users, it is a significant expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED display, tracks everything with premier GPS, built-in flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and satellite functions need ongoing subscription, limited Garmin Pay financial compatibility, voice features are slow, basic wearable functionality versus Apple/Google/Samsung watches.
