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

This most recent iteration of the flagship Fenix outdoor timepiece includes a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or satellite links.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge mobile tech, along with an available state-of-the-art microLED display in a special edition. This is Garmin's top device and designed to be the single tool required to explore virtually anywhere and track all your movements.

That makes it an very 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 cost of the standard Fenix 8.

You do receive a significant features for your money, with best-in-class workout, activity and outdoor monitoring. Its complete offline mapping of the world can automatically guide you back to the trail if you lose your way without a phone, and look excellent on the sizable, crisp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other models, so it is a big watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of smartwatch battery life even with the screen always active, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. However unlike Apple or Google's satellite-enabled devices, emergency messaging is not provided for free.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, calls and LiveTrack position tracking – so your friends or loved ones can monitor you while engaged in jogging, biking or similar activities – along with SOS orbital SOS alerts.

Location updates and texts over satellite are then billed on top, with more expensive plans including various quotas of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have got it set up, you simply head out the door without your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you are able to make and take calls, dispatch texts and generally keep in touch with your relatives and friends.

Whenever you text someone, Garmin sends 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 communicate reciprocally using text or voice messages, and initiate 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 composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable canned responses you can use to speed things up. Spoken recordings and calls work acceptably, though as with most smartwatches, you’re unlikely going to want to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can set it up to on its own transmit a link to chosen contacts every time you begin an exercise, so they can track your live position on a map. It’s excellent for following competition progress, but it mostly acts as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally functioned effectively, although the actual location has sometimes been delayed when moving in and out of strong LTE signal.

These features are available on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide shows you how to locate the line of sight to the satellite, 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, though it is important to remember that satellite coverage is limited to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally repairable with services available via the support site. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused components. Garmin offers disposal schemes on recent purchases.

Price

This Fenix 8 Pro is priced 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, call functionality and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re without signal.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you wish to have someone monitor you remotely while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

It is very liberating to be outside without a phone, but that capability carries quite a price, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to enable the service. Fortunately it isn’t reliant on your phone carrier so works with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, biking or hiking, but still desires to be trackable and reachable. For everyone else, it is a lot of money when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED display, monitors everything with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: very costly, LTE and orbital functions need monthly subscription, limited Garmin Pay financial support, speech features are slow, limited wearable functionality versus Apple/Google/Samsung watches.
