Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Texting

This most recent iteration of the premium Fenix outdoor watch includes a life-saving capability: no-phone messaging and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating cutting-edge cellular tech, plus an optional state-of-the-art microLED display in a special edition. It is Garmin's top model and designed to be the only gadget required to explore virtually any location and track every activity.

This 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 variant with microLED screen – almost twice the price of the standard Fenix 8.

Users receive a lot of functionality for your money, with industry-leading fitness, activity and adventure tracking. Its full offline mapping of the world can automatically direct you return to the path if you get lost absent a phone, and look excellent on the large, sharp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life despite the screen always active, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital service service instead of depending on a watch plan tied to your phone carrier, as with other smartwatches. But in contrast to competing satellite-enabled products, SOS communication is not included for free.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE text and audio messages, calls and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out jogging, biking or similar activities – along with SOS orbital SOS alerts.

Location updates and messages over satellite are then charged on top, with higher-tier subscriptions including different quotas of satellite use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you just head out outside without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you can make and take calls, send texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally via text or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of customisable pre-set replies you can use to expedite communication. Voice messages and calls perform acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for lengthy discussions 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 start an activity, so they can track your real time location on a map. It’s excellent for following competition progress, but it mostly acts as a utility for someone you trust to know your whereabouts in case something happens. It has generally functioned well, though the real location has occasionally lagged when moving in and out of strong LTE coverage.

These capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A guide displays you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, though 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 above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available through the support site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused components. Garmin provides recycling schemes on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service 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 regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive outdoor device 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 does so without requiring anything else.

It is quite freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to provide the service. Fortunately it is not dependent on your phone provider so works with any make of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but still wants to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, monitors everything with premier GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and satellite features require ongoing payment, restricted Garmin Pay bank compatibility, speech capabilities are slow, limited smartwatch functionality compared with Apple/Google/Samsung watches.
