Garmin Fenix 8 Pro Analysis: Integrated LTE and Orbital Communication for Phone-Free Texting

The newest iteration of the premium Fenix adventure watch brings a life-saving capability: phone-free messaging and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular technology, plus an available state-of-the-art microLED display in a special edition. It is the brand's premier device and engineered to be the only gadget needed to venture virtually anywhere and monitor 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 model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the cost of the standard Fenix 8.

You do get a significant features for your money, with industry-leading workout, activity and outdoor tracking. The complete offline mapping of the globe can automatically direct you back to the path if you get lost absent a phone, and appear great on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm size available in other models, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed does have an additional day of watch battery life despite the screen on all the time, enduring a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company uses its own inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan linked to your mobile provider, as with other wearables. But in contrast to competing satellite-capable devices, emergency messaging is not provided for free.

Rather, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and audio messages, call functionality and LiveTrack location sharing – so your friends or family can monitor you while engaged in running, biking or similar activities – plus emergency satellite SOS alerts.

Location updates and messages via orbital are then billed additionally, with more expensive plans offering different quotas of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After you have got it set up, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you can place and receive calls, send texts and generally keep in touch with your relatives and friends.

When you text someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or spoken communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a phone number is enough to register for texts.

Messaging on the watch works fine but typing out texts on the tiny 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 work OK, though as with the majority of wearables, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a URL to selected contacts every time you start an exercise, so they can follow your real time position on a map. It’s excellent for monitoring competition progress, but it primarily acts as a tool for someone you trust to know your whereabouts in case an incident occurs. It has typically functioned well, although the real position has sometimes been delayed when transitioning in and out of good LTE coverage.

These features are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance displays you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is essential to remember that orbital service is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options offered through the customer service site. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin offers recycling schemes on recent purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent adventure 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 impressive outdoor device for those that desire to be unplugged. If you wish to have someone monitor you remotely while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

It is very liberating to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the substantial cost of the watch and the recurring fee of the inReach service to provide the service. Fortunately it is not reliant on your phone provider so functions with any brand of smartphone and carrier.

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

Advantages: LTE and satellite communication, high-luminance OLED screen, monitors all activities with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and orbital functions need monthly payment, limited Garmin Pay bank compatibility, voice capabilities are slow, limited smartwatch features versus Apple/Google/Samsung watches.
