Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Texting

This most recent iteration of the flagship Fenix adventure watch brings a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating cutting-edge mobile tech, along with an available state-of-the-art microLED screen in a limited edition. This is Garmin's top device and designed to be the single tool needed to explore almost any location and monitor all your movements.

This positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the cost of the standard Fenix 8.

You do receive a lot of functionality for your investment, with industry-leading fitness, movement and outdoor tracking. The complete offline maps of the globe can automatically guide you return to the trail if you lose your way absent a phone, and look excellent on the sizable, crisp and super-bright touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed does have an additional day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan linked to your mobile carrier, as with other smartwatches. However unlike competing satellite-capable products, SOS communication is not provided for no cost.

Instead, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messaging, call functionality and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while engaged in running, biking or similar pursuits – along with emergency orbital SOS messaging.

Check-ins and messages over orbital are then charged additionally, with higher-tier subscriptions including various allowances of orbital use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have completed setup, you just venture outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, send texts and generally stay connected with your family and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via typed or spoken messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Messaging on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It includes a set of customisable pre-set replies you can send to expedite communication. Spoken recordings and calls perform acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can configure to automatically send a URL to selected contacts every time you start an activity, so they can track your live position on a map. It’s excellent for following race progress, but it primarily acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally functioned well, though the actual position has sometimes been delayed when transitioning in and out of strong LTE coverage.

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

A guide 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 safety feature, though it is essential to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with services available via the support site. 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 recycled materials. Garmin offers recycling programs on new purchases.

Cost

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re without 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 remote areas, the Garmin does so without requiring additional gear.

It is very liberating to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the service. At least it isn’t reliant on your phone provider so works with all brand of smartphone and network.

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

Advantages: LTE and satellite communication, high-luminance OLED screen, tracks everything with premier GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: very expensive, LTE and satellite functions require ongoing payment, limited Garmin Pay financial support, voice capabilities are slow, limited wearable features compared with Apple/Google/Samsung watches.
