The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Texting

The latest version of Garmin's premium Fenix adventure watch includes a potentially lifesaving feature: phone-free communication and emergency messaging via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile technology, along with an optional advanced microLED display in a limited edition. It is Garmin's premier model and designed to be the only tool needed to venture virtually anywhere and track all your movements.

That positions it as an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost twice the price of the regular Fenix 8.

You do get a lot of functionality for your money, with best-in-class fitness, movement and adventure tracking. The full offline maps of the globe can seamlessly guide you back to the trail if you lose your way without 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 sizes, not the smaller 43mm size found in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life despite the screen on all the time, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calls 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 provider, as with other wearables. However in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for free.

Instead, subscriptions start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack location sharing – so your friends or loved ones can monitor you while engaged in jogging, biking or similar activities – plus SOS satellite SOS messaging.

Check-ins and messages over satellite are then charged additionally, with more expensive plans including various allowances of satellite usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you just head out the door without your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and companions.

When you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then message back and forth via text or voice communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable pre-set replies you can send to expedite communication. Voice recordings and calls perform acceptably, although as with the majority of wearables, you’re not going to wish to use it for lengthy discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can configure to automatically send a URL to chosen contacts every time you begin an exercise, so they can track your live position on a map. It’s excellent for monitoring competition progress, but it primarily acts as a tool for someone you rely on to know your location in case something happens. It has generally functioned effectively, though the actual position has occasionally been delayed when moving in and out of good LTE coverage.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A on-screen assistance shows you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, 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 latitude.

Sustainability

The watch is generally serviceable with options offered via the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling schemes on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages 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 texting, call functionality and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re without signal.

The result is an increasingly remarkable outdoor tool for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin does so without needing anything else.

It is very liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the features. At least it is not reliant on your phone carrier so works with all make of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, biking or trekking, but nevertheless wants to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors all activities with best-in-class GPS, built-in torch, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: extremely costly, LTE and orbital functions require monthly subscription, limited Garmin Pay financial compatibility, voice capabilities are slow, basic smartwatch features compared with Apple/Google/Samsung watches.
