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

The latest version of Garmin's flagship Fenix adventure timepiece introduces a potentially lifesaving capability: no-phone communication and emergency alerts via 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge cellular technology, along with an optional advanced microLED display in a special edition. It is the brand's premier device and designed to be the only tool needed to explore virtually any location and track all your movements.

That makes it an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the price of the standard Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class fitness, movement and outdoor tracking. The full offline mapping of the globe can seamlessly direct you return to the trail if you get lost without a phone, and appear excellent on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size available in other models, so it is a big watch for bigger wrists. But the 47mm OLED version as tested does have an additional day of watch battery life even with the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your mobile provider, as with other smartwatches. However in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not included for free.

Instead, subscriptions begin from £7.99 or similar a month, which provides unlimited LTE SMS and voice messages, calls and LiveTrack location tracking – so your contacts or loved ones can monitor you while out running, cycling or comparable activities – along with emergency satellite SOS alerts.

Location updates and messages via orbital are then charged additionally, with more expensive plans including different allowances of orbital usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have got it set up, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you are able to make and take calls, send texts and overall stay connected with your relatives and friends.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via text or voice messages, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a phone number is enough to sign up for texts.

Messaging on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable canned replies you can send to expedite communication. Spoken recordings and calls work OK, although as with the majority of smartwatches, you’re not going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can set it up to on its own send a URL to chosen contacts whenever you start an activity, so they can follow your real time position on a map. It’s excellent for monitoring race performance, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally worked well, although the real location has sometimes lagged when moving in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is essential to note that satellite coverage is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with options available via the support portal. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin offers disposal programs on recent purchases.

Cost

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 begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re out of coverage.

Outcome is an increasingly remarkable adventure device for those that want to be phone-free. If you want to have someone keep an eye on you from afar 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 outside without a phone, but that capability comes at quite a price, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to provide the features. At least it isn’t reliant on your phone provider so works with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when jogging, biking or trekking, but still wants to be locatable and reachable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, monitors everything with premier GPS, built-in flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Drawbacks: very expensive, LTE and satellite features need ongoing payment, limited Garmin Pay financial support, speech capabilities are sluggish, basic wearable features versus competing watches.
