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

The newest iteration of Garmin's top-tier Fenix adventure watch brings a potentially lifesaving capability: no-phone messaging and SOS alerts via 4G LTE or orbital links.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge cellular tech, plus an optional advanced microLED screen in a special edition. This is the brand's premier device and designed to be the only tool required to venture virtually anywhere and track every activity.

That makes it an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the price of the standard Fenix 8.

You do receive a significant features for your investment, with best-in-class workout, movement and outdoor tracking. Its complete offline maps of the globe can seamlessly guide you return to the trail if you get lost absent a phone, and look excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as tested does have an extra day of watch battery life despite the screen always active, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription service rather than depending on a watch plan linked to your phone carrier, like other smartwatches. However unlike Apple or Google's satellite-capable devices, SOS communication is not included for free.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE text and audio messaging, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while engaged in running, biking or similar activities – plus SOS orbital SOS messaging.

Location updates and texts via satellite are then charged additionally, with more expensive plans offering various allowances of satellite use, increasing to a £50 a month all-inclusive 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 outside minus your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you are able to place and receive calls, send texts and overall keep in touch with your family and friends.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally using typed or spoken messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Messaging on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable canned replies you can use to speed things up. Voice messages and calls work OK, although as with most wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to on its own send a URL to chosen contacts every time you start an activity, so they can follow your real time position on a map. It’s excellent for monitoring competition performance, but it primarily acts as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has typically worked effectively, though the actual location has occasionally been delayed when moving in and out of good LTE signal.

All of these features are available on other Garmin devices 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 check-ins and SOS SOS.

A guide shows 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 unexpectedly easy to use and could be a vital lifeline, however it is important to note that orbital service is limited to the US continent, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options 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 components. Garmin provides recycling programs on recent purchases.

Cost

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 cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

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

Outcome is an even more remarkable adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin does so without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal price of the watch and the recurring fee of the inReach service to enable the service. At least it is not reliant on your phone carrier so functions with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, biking or trekking, but still wants to be locatable and reachable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks all activities with premier GPS, integrated torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: very expensive, LTE and orbital features require monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are slow, basic smartwatch features compared with competing watches.
