Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for No-Phone Messaging

This latest iteration of the premium Fenix outdoor watch introduces a life-saving feature: no-phone messaging and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating cutting-edge cellular tech, along with an optional advanced microLED screen in a special edition. This is Garmin's top device and designed to be the single gadget needed to explore virtually any location and track every activity.

That positions it as an very 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 screen – nearly double the price of the regular Fenix 8.

You do get a significant functionality for your investment, with industry-leading fitness, movement and adventure tracking. The full offline maps of the globe can seamlessly guide you back to the path if you lose your way absent a phone, and appear excellent on the large, crisp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as tested boasts an extra day of watch battery life even with the display on all the time, enduring a solid eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital subscription service rather than depending on a watch plan linked to your phone provider, as with other smartwatches. But unlike Apple or Google's satellite-capable products, emergency messaging is not provided for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE SMS and voice messages, calls and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out running, biking or similar activities – along with SOS orbital SOS alerts.

Location updates and texts over orbital are then billed on top, with higher-tier plans including various allowances of satellite use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the functionality.

After you have got it set up, you simply head out outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, send texts and generally stay connected with your family and friends.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It has a set of personalizable canned replies you can send to expedite communication. Voice recordings and calls work acceptably, though as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the handiest function. You can set it up to automatically transmit a link to chosen contacts whenever you start an activity, so they can follow your real time location on a map. It’s excellent for monitoring race progress, but it mostly serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has typically functioned well, though the real location has occasionally been delayed when moving in and out of strong LTE signal.

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

A on-screen assistance displays you how to find the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is important to remember that satellite coverage is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally repairable with services offered via the customer service site. The battery is rated to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re out of coverage.

The result is an increasingly impressive outdoor device for those that desire to be unplugged. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is quite freeing to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to provide the features. At least it is not dependent on your phone provider so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless wants to be locatable and contactable. For other users, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED display, tracks all activities with best-in-class GPS, integrated flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Cons: extremely costly, LTE and satellite features require ongoing subscription, limited Garmin Pay financial compatibility, voice capabilities are sluggish, basic smartwatch features versus Apple/Google/Samsung watches.
