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

The latest model of Garmin's flagship Fenix adventure watch brings a potentially lifesaving capability: no-phone communication and SOS alerts using 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding cutting-edge mobile tech, plus an available advanced microLED display in a limited edition. It is Garmin's premier device and designed to be the single tool required to explore almost any location and track every activity.

That positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

You do receive a significant functionality for your investment, with best-in-class fitness, movement and adventure monitoring. Its full offline maps of the globe can automatically direct you back to the path if you get lost absent a phone, and appear excellent on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as tested does have an additional day of smartwatch battery life even with the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

The company operates its own inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your mobile provider, as with other smartwatches. But unlike competing satellite-capable products, emergency communication is not included for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE text and audio messaging, calls and LiveTrack location tracking – so your friends or loved ones can monitor you while engaged in running, cycling or comparable pursuits – along with emergency satellite SOS messaging.

Location updates and texts via orbital are then charged additionally, with higher-tier subscriptions including different allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have got it set up, you simply venture the door without your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you are able to make and take calls, send texts and generally stay connected with your relatives and friends.

When you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via typed or voice messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It has a collection of customisable pre-set replies you can use to speed things up. Spoken recordings and calls perform acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can configure to automatically transmit a URL to chosen contacts every time you begin an activity, so they can track your real time position on a map. It’s excellent for monitoring race performance, but it mostly serves as a tool for someone you trust to know your location in case an incident occurs. It has typically functioned effectively, although the actual location has sometimes been delayed when transitioning in and out of good LTE coverage.

These features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide displays you how to find the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, though it is important to note that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options offered via the customer service site. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused components. Garmin offers disposal schemes on recent purchases.

Price

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

Verdict

The Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without signal.

Outcome is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is quite liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to provide the service. Fortunately it isn’t reliant on your phone carrier so functions with all brand of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, cycling or trekking, but still wants to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED display, tracks everything with best-in-class GPS, built-in torch, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: very costly, LTE and orbital features need monthly payment, restricted Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch functionality versus competing watches.
