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

This most recent iteration of the top-tier Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and SOS messaging using 4G LTE or orbital connections.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular technology, plus an optional state-of-the-art microLED screen in a special edition. This is the brand's top device and designed to be the only tool needed to explore virtually anywhere and track 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 version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the price of the standard Fenix 8.

You do get a lot of functionality for your investment, with industry-leading workout, activity and adventure monitoring. The full offline mapping of the world can seamlessly direct you return to the path if you lose your way absent a phone, and appear excellent on the sizable, sharp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm version found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life even with the display always active, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and satellite service plan rather than relying on a watch plan tied to your phone provider, as with other wearables. But unlike competing satellite-enabled products, emergency communication is not included for free.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE SMS and audio messaging, call functionality and LiveTrack position tracking – so your contacts or family can monitor you while engaged in jogging, cycling or similar activities – along with SOS orbital SOS messaging.

Location updates and messages via satellite are then charged on top, with higher-tier plans including various quotas of orbital use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you simply venture the door without your phone and the watch will link 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 friends.

Whenever you text someone, Garmin dispatches them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using text or voice messages, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, just 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 time-consuming. It includes a set of personalizable pre-set responses you can send to speed things up. Voice messages and calls work OK, although as with most wearables, you’re not going to wish to use it for extended conversations as the quality is less than ideal.

LiveTrack is the handiest feature. You can set it up to automatically transmit a link to chosen contacts every time you begin an activity, so they can track your live position on a map. It’s excellent for monitoring competition performance, but it mostly acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has typically worked well, though the actual location has occasionally been delayed when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is essential to note that orbital coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with services available through the support portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any reused materials. Garmin provides disposal schemes on recent purchases.

Cost

This 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).

Verdict

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of signal.

The result is an increasingly remarkable adventure tool for those that want to be unplugged. If you want to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is quite freeing to be outside without a phone, but that capability carries a significant price, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to enable the service. At least it isn’t dependent on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but still wants to be trackable and reachable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, high-luminance OLED display, monitors all activities with best-in-class GPS, integrated torch, voice and offline commands, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite functions require monthly subscription, limited Garmin Pay financial support, speech features are slow, basic wearable features versus Apple/Google/Samsung watches.
