The Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Messaging

This latest iteration of Garmin's top-tier Fenix adventure watch includes a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge cellular technology, along with an available state-of-the-art microLED screen in a limited edition. This is Garmin's premier model and designed to be the single tool required to explore virtually anywhere and track all your movements.

This makes it an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to 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.

Users get a lot of functionality for your money, with industry-leading fitness, activity and outdoor tracking. The full offline mapping of the world can automatically direct you back to the trail if you get lost without a phone, and look excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED version as tested does have an additional day of watch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

The company uses its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan tied to your phone provider, as with other wearables. However in contrast to competing satellite-enabled devices, emergency communication is not included for no cost.

Instead, subscriptions start at £7.99 or similar a month, which includes limitless LTE SMS and voice messages, calls and LiveTrack position tracking – so your friends or family can monitor you while out jogging, biking or similar pursuits – along with emergency satellite SOS alerts.

Check-ins and texts over satellite are then billed additionally, with higher-tier subscriptions including various quotas of satellite use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can evaluate the functionality.

After you have completed setup, you just venture the door without your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, dispatch texts and generally stay connected with your relatives and companions.

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

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a set of customisable canned replies you can use to expedite communication. Voice messages and calls work OK, although as with most wearables, you’re unlikely going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest feature. You can configure to on its own send a link to selected contacts every time you start an activity, so they can track your live location on a map. It’s great for following competition performance, but it mostly acts as a utility for someone you trust to be aware of your location in case an incident occurs. It has generally functioned effectively, though the actual location has occasionally lagged when transitioning in and out of strong LTE coverage.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance displays you how to find the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is essential to remember that orbital service is limited to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with options available via the customer service site. The battery is rated to retain at least 90% of its original power after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal programs on recent purchases.

Price

This 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).

Verdict

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

Outcome is an increasingly impressive outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin does so without requiring anything else.

It is very liberating to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal price of the watch and the monthly fee of the inReach service to provide the service. Fortunately it is not reliant on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, biking or hiking, but still wants to be trackable and reachable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite communication, super-bright OLED screen, monitors all activities with premier GPS, built-in torch, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: extremely expensive, LTE and orbital features require ongoing subscription, limited Garmin Pay bank support, speech features are slow, basic smartwatch features compared with Apple/Google/Samsung watches.
