The Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for No-Phone Messaging

This most recent model of Garmin's top-tier Fenix outdoor watch brings a potentially lifesaving feature: phone-free messaging and emergency messaging via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating cutting-edge cellular technology, along with an available state-of-the-art microLED screen in a special edition. It is the brand's premier device and engineered to be the only tool required to explore virtually any location and monitor all your movements.

That makes it an extremely expensive 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 edition with microLED display – almost twice the price of the standard Fenix 8.

Users get a significant functionality for your money, with industry-leading fitness, movement and adventure monitoring. Its complete offline maps of the globe can automatically guide you return to the trail if you lose your way absent a phone, and appear great on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other models, so it is a large watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan tied to your mobile provider, as with other wearables. But unlike competing satellite-enabled products, emergency messaging is not provided for no cost.

Rather, plans begin from £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, calls and LiveTrack position sharing – so your contacts or family can keep an eye on you while engaged in running, biking or comparable activities – along with SOS orbital SOS alerts.

Location updates and messages via orbital are then charged additionally, with more expensive subscriptions offering different allowances of orbital use, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the service.

After you have got it set up, you just head out outside without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you can make and take calls, send texts and overall stay connected with your relatives and friends.

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

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can send to expedite communication. Voice recordings and calls perform acceptably, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful feature. You can configure to automatically transmit a link to selected contacts whenever you begin an activity, so they can follow your live position 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 whereabouts in case something happens. It has generally functioned well, although the actual position has occasionally been delayed when moving in and out of good LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is essential to note that orbital coverage is restricted 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 serviceable with services available through the support site. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling programs on recent purchases.

Price

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

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly impressive outdoor device for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

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

The Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless desires to be locatable and reachable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, integrated torch, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very costly, LTE and orbital functions need ongoing payment, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, basic smartwatch functionality compared with competing watches.
