Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

The newest version of the premium Fenix adventure timepiece brings a life-saving feature: no-phone messaging and SOS messaging using 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by incorporating new mobile tech, along with an optional state-of-the-art microLED screen in a special edition. It is the brand's premier model and designed to be the only tool required to venture almost anywhere and monitor all your movements.

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

Users receive a significant functionality for your money, with best-in-class workout, movement and outdoor monitoring. The full offline mapping of the globe can seamlessly guide you back to the path if you lose your way absent a phone, and look excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm version found in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as reviewed boasts an extra day of watch battery life even with the display always active, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription service rather than relying on a watch plan tied to your phone carrier, as with other smartwatches. However in contrast to Apple or Google's satellite-capable devices, emergency messaging is not included for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while out running, cycling or similar pursuits – plus SOS orbital SOS messaging.

Check-ins and messages via satellite are then billed on top, with higher-tier subscriptions offering different quotas of satellite usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you just venture the door without your phone and the watch will connect to LTE. You can not use it for playing music or similar tasks, but you are able to make and take calls, send texts and generally stay connected with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally using typed or voice messages, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a phone number is sufficient to sign up for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of customisable canned replies you can send to speed things up. Voice messages and calls perform OK, though as with most wearables, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can set it up to on its own transmit a URL to selected contacts every time you start an activity, so they can follow your real time location on a map. It’s excellent for following competition progress, but it mostly serves as a tool for someone you rely on to be aware of your location in case something happens. It has generally worked well, although the real position has occasionally lagged when moving in and out of strong 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 activates on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is essential to remember that orbital coverage is limited to the US mainland, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with services available via the customer service site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled components. Garmin provides disposal 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 optional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of coverage.

The result is an even more remarkable outdoor device for those that desire to be unplugged. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is very liberating to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to enable the service. At least it is not dependent on your phone carrier so works with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED screen, tracks all activities with premier GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: extremely expensive, LTE and satellite functions require ongoing subscription, restricted Garmin Pay bank support, voice capabilities are slow, basic smartwatch features compared with Apple/Google/Samsung watches.
