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

This newest version of Garmin's premium Fenix adventure watch includes a potentially lifesaving capability: no-phone communication and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new mobile technology, plus an available advanced microLED screen in a special edition. This is the brand's top model and engineered to be the single tool needed to explore almost anywhere and track all your movements.

This makes it an extremely expensive option, 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 screen – nearly twice the cost of the regular Fenix 8.

You do get a significant functionality for your investment, with best-in-class workout, activity and outdoor tracking. The full offline maps of the world can automatically direct you return to the path if you lose your way without a phone, and appear great on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the more compact 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as tested does have an extra day of smartwatch battery life despite the display on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital service service rather than depending on a watch plan tied to your mobile carrier, like other smartwatches. But in contrast to competing satellite-capable products, SOS communication is not provided for free.

Instead, subscriptions begin from £7.99 or similar a month, which includes limitless LTE text and voice messaging, calls and LiveTrack position sharing – so your contacts or loved ones can monitor you while out running, biking or similar activities – plus SOS satellite SOS alerts.

Check-ins and texts over orbital are then charged additionally, with higher-tier plans offering various quotas of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the service.

Once you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you can place and receive calls, send texts and generally keep in touch with your family and companions.

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

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It includes a set of customisable canned responses you can send to speed things up. Voice recordings and calls perform OK, although as with most smartwatches, you’re not going to want to use it for lengthy conversations as the quality is not fantastic.

LiveTrack is the handiest function. You can configure to automatically transmit a link to selected contacts every time you begin an exercise, so they can track your live location on a map. It’s excellent for following competition progress, but it primarily serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned well, although the real position has occasionally been delayed when moving in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to locate 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 crucial lifeline, however it is important to remember that satellite coverage is limited to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with options offered through the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal programs on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, location update 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 remotely while running after dark or in the middle of nowhere, the Garmin does so without needing additional gear.

It is very liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to enable the features. At least it isn’t dependent on your phone provider so functions with any make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, biking or hiking, but still wants to be trackable and reachable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, super-bright OLED display, monitors all activities with premier GPS, built-in torch, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: extremely expensive, LTE and orbital features need ongoing payment, restricted Garmin Pay bank support, voice features are sluggish, limited smartwatch functionality compared with Apple/Google/Samsung watches.
