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

This latest model of Garmin's flagship Fenix outdoor watch brings a life-saving feature: phone-free messaging and SOS alerts using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new cellular tech, along with an optional advanced microLED display in a limited edition. It is Garmin's premier model and designed to be the single tool needed to explore virtually any location and monitor every activity.

That positions it as an extremely pricey option, starting at £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 variant with microLED display – almost twice the price of the regular Fenix 8.

Users get a significant functionality for your investment, with best-in-class workout, activity and adventure monitoring. Its complete offline maps of the world can automatically guide you return to the path if you get lost without a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital service service rather than relying on a watch plan linked to your mobile carrier, like other wearables. However unlike competing satellite-enabled devices, SOS messaging is not included for free.

Instead, subscriptions begin from £7.99 or similar a month, which provides limitless LTE text and audio messaging, call functionality and LiveTrack position sharing – so your contacts or family can monitor you while out jogging, cycling or similar pursuits – plus emergency orbital SOS alerts.

Check-ins and texts over satellite are then charged on top, with more expensive subscriptions including various quotas of satellite usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can test out the service.

Once you have completed setup, you simply head out the door minus your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you can make and take calls, dispatch texts and overall keep in touch with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via typed or spoken messages, and make voice calls. Your recipient 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 adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set replies you can use to speed things up. Spoken messages and calls work acceptably, although as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a link to selected contacts whenever you begin an activity, so they can track your live location on a map. It’s excellent for monitoring race progress, but it mostly serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has typically worked effectively, though the real location has occasionally lagged when transitioning in and out of strong LTE signal.

These features are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide 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 safety feature, however it is important to remember that satellite service is limited to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally repairable with options available via the support portal. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled 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 optional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable adventure device for those that want to be phone-free. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

It is quite freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to enable the features. Fortunately it isn’t dependent on your phone provider so functions with all brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, biking or hiking, but still desires to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED screen, tracks everything with premier GPS, integrated torch, voice and offline commands, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: very expensive, LTE and satellite functions need monthly subscription, limited Garmin Pay financial support, speech features are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
