The Fenix 8 Pro Analysis: Integrated LTE and Orbital Communication for Phone-Free Messaging

The latest iteration of Garmin's flagship Fenix adventure watch introduces a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating new cellular technology, plus an available advanced microLED display in a special edition. It is Garmin's top device and engineered to be the only gadget required to explore virtually any location and monitor every activity.

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

Users get a lot of functionality for your money, with best-in-class workout, movement and outdoor monitoring. The full offline maps of the globe can seamlessly direct you back to the trail if you lose your way absent a phone, and look excellent on the sizable, sharp and super-bright touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of smartwatch battery life even with the screen on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan tied to your phone provider, as with other wearables. However in contrast to competing satellite-capable products, SOS communication is not provided for free.

Instead, subscriptions begin from £7.99 or similar a month, which provides limitless LTE text and audio messaging, calls and LiveTrack position sharing – so your contacts or family can keep an eye on you while out running, biking or comparable pursuits – plus emergency orbital SOS messaging.

Location updates and messages over satellite are then charged on top, with higher-tier subscriptions offering various allowances of satellite use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the service.

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

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally using text or voice communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a phone number is enough to register for texts.

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable pre-set replies you can send to speed things up. Voice recordings and calls perform acceptably, although as with the majority of wearables, you’re not going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to on its own send a link to selected contacts every time you begin an activity, so they can track your live location on a map. It’s great for following race progress, but it primarily serves as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally worked well, though the actual location has sometimes been delayed when transitioning in and out of strong LTE coverage.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A guide displays you how to find the clear view to the orbital system, which then sends and receives 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 continent, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with options available through the support portal. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch does not contain any recycled components. Garmin offers recycling programs on new purchases.

Cost

The Fenix 8 Pro costs 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).

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite communication, location update and SOS SOS for when you’re without signal.

Outcome is an even more remarkable outdoor tool for those that desire to be unplugged. If you wish to have someone monitor you from afar while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring anything else.

It is quite liberating to be outdoors without a phone, but that capability carries a significant price, both in terms of the colossal price of the watch and the recurring subscription of the inReach plan to enable the service. At least it isn’t reliant on your phone carrier so works with all make 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 nevertheless wants to be trackable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

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 endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and satellite features require monthly subscription, limited Garmin Pay bank support, voice features are sluggish, limited wearable functionality versus Apple/Google/Samsung watches.
