The Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

This latest version of the premium Fenix outdoor watch introduces a potentially lifesaving feature: phone-free communication and SOS alerts using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new cellular technology, plus an available state-of-the-art microLED screen in a special edition. This is Garmin's top model and engineered to be the single tool required to explore virtually anywhere and track all your movements.

That positions it as an very pricey 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 edition with microLED screen – nearly double the price of the standard Fenix 8.

You do get a lot of functionality for your money, with best-in-class workout, movement and outdoor tracking. Its complete offline mapping of the globe can seamlessly guide you return to the trail if you get lost absent a phone, and appear excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of watch battery life even with the display on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

The company operates its own inReach LTE (4G) and satellite service service instead of depending on a watch plan linked to your phone provider, as with other smartwatches. But unlike competing satellite-capable devices, SOS messaging is not included for free.

Rather, plans start at £7.99 or similar a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack location tracking – so your friends or family can keep an eye on you while engaged in running, cycling or comparable activities – along with SOS orbital SOS messaging.

Check-ins and messages over satellite are then charged additionally, with higher-tier plans including different quotas of satellite use, climbing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the service.

Once you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you can make and take calls, send texts and generally stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger app, 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 application, only a phone number is sufficient to register for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is slow. It has a collection of personalizable pre-set responses you can send to speed things up. Spoken messages and calls perform acceptably, although as with most wearables, you’re not going to wish to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can configure to automatically send a link to selected contacts every time you begin an exercise, so they can track your live location on a map. It’s great for monitoring competition performance, but it primarily acts as a tool for someone you trust to know your whereabouts in case an incident occurs. It has typically functioned effectively, though the actual location has sometimes lagged when moving in and out of good LTE signal.

All of these capabilities 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 send texts, location check-ins and emergency SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, however it is important to remember that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with options offered via the customer service site. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused materials. Garmin provides disposal programs on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re without signal.

The result is an even more remarkable outdoor tool for those that want to be unplugged. If you want to have someone monitor you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

This is very liberating to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to enable the features. At least it is not dependent on your phone provider so works 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 jogging, cycling or trekking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in torch, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: very costly, LTE and satellite functions require ongoing payment, restricted Garmin Pay financial compatibility, speech features are slow, basic smartwatch features compared with competing watches.
