Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

This latest model of Garmin's flagship Fenix outdoor watch brings a potentially lifesaving feature: no-phone communication and emergency alerts via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular tech, along with an optional advanced microLED screen in a special edition. This is Garmin's premier device and engineered to be the single gadget needed to explore almost anywhere and monitor all your movements.

This makes it an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the price of the standard Fenix 8.

You do receive a lot of functionality for your money, with industry-leading fitness, movement and outdoor monitoring. The complete offline mapping of the world can seamlessly direct you back to the trail if you lose your way without a phone, and appear great on the large, sharp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as tested boasts an additional day of smartwatch battery life even with the display on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital service service instead of relying on a watch plan linked to your mobile carrier, like other smartwatches. However in contrast to competing satellite-enabled devices, emergency messaging is not provided for free.

Instead, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messages, call functionality and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while out running, biking or comparable activities – along with emergency satellite SOS messaging.

Location updates and texts via satellite are then charged additionally, with higher-tier plans offering various allowances of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have got it set up, you just venture the door without your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you can place and receive calls, dispatch texts and overall stay connected with your relatives and companions.

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

Texting on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a set of customisable canned replies you can send to speed things up. Spoken messages and calls work OK, though as with the majority of wearables, you’re not going to wish to use it for extended conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful function. You can configure to automatically transmit a link to chosen contacts whenever you start an exercise, so they can follow your real time position on a map. It’s excellent for following race progress, but it primarily acts as a utility for someone you trust to know your location in case something happens. It has generally functioned effectively, although the real position has sometimes been delayed when transitioning in and out of good LTE signal.

These features are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A guide displays you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to remember that satellite coverage is limited to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services offered via the customer service portal. The battery is rated to retain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin offers recycling schemes on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re without signal.

The result is an increasingly impressive adventure device for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

This is quite freeing to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to provide the features. 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 running, cycling or hiking, but nevertheless wants to be locatable and contactable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in torch, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: very expensive, LTE and satellite functions require monthly subscription, limited Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch functionality compared with competing watches.
