The Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for Phone-Free Messaging

This newest model of Garmin's flagship Fenix adventure watch introduces a potentially lifesaving capability: no-phone messaging and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge mobile technology, along with an available state-of-the-art microLED screen in a special edition. It is the brand's top model and designed to be the single tool required to venture virtually anywhere and monitor every activity.

This positions it as an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £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.

You do receive a significant features for your investment, with best-in-class workout, movement and outdoor monitoring. The complete offline maps of the world can automatically direct you return to the path if you lose your way absent a phone, and look great on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life even with the display always active, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan tied to your phone provider, as with other wearables. But in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE text and voice messaging, call functionality and LiveTrack location sharing – so your friends or loved ones can monitor you while out jogging, biking or comparable pursuits – along with SOS orbital SOS alerts.

Location updates and texts over satellite are then billed on top, with more expensive subscriptions including various allowances of orbital usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have completed setup, you just head out outside minus 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 stay connected with your relatives and friends.

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

Texting on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable canned replies you can send to speed things up. Voice messages and calls perform OK, though as with most wearables, you’re not going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the handiest feature. You can set it up to on its own send a link to chosen contacts every time you start an activity, so they can follow your live location on a map. It’s great for following competition performance, but it primarily serves as a tool for someone you trust to know your location in case something happens. It has generally worked well, though the real position has occasionally lagged when transitioning 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 emergency SOS.

A guide shows you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, however it is essential to remember that orbital service is restricted to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered via the support portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling programs on recent purchases.

Price

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re without signal.

Outcome is an increasingly impressive outdoor tool for those that want to be phone-free. 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 quite freeing 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 recurring fee of the inReach service to provide the features. At least it isn’t reliant on your phone provider so works with any make of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Cons: very expensive, LTE and satellite features need ongoing subscription, limited Garmin Pay bank compatibility, speech capabilities are slow, limited wearable functionality compared with competing watches.
