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

This newest iteration of the flagship Fenix outdoor timepiece introduces a potentially lifesaving capability: phone-free communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an available state-of-the-art microLED screen in a special edition. This is the brand's top device and designed to be the only gadget needed to explore almost any location and track all your movements.

That makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the price of the regular Fenix 8.

You do get a lot of functionality for your investment, with best-in-class fitness, activity and adventure monitoring. Its full offline mapping of the globe can seamlessly guide you return to the path if you get lost absent a phone, and appear great on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other models, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life despite the screen always active, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your phone carrier, like other wearables. However in contrast to competing satellite-capable products, emergency messaging is not included for no cost.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE SMS and voice messages, calls and LiveTrack location tracking – so your contacts or family can monitor you while engaged in running, biking or comparable pursuits – along with emergency orbital SOS messaging.

Location updates and messages over satellite are then charged on top, with higher-tier subscriptions offering different allowances of satellite usage, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the service.

Once you have got it set up, you just venture outside without your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you are able to place and receive calls, send texts and overall stay connected with your relatives and companions.

When you text 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 reciprocally via typed or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to sign up for texts.

Messaging on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set replies you can use to expedite communication. Voice recordings and calls perform OK, although as with the majority of wearables, you’re not going to wish to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can set it up to on its own send a link to selected contacts whenever you begin an activity, so they can track your live position on a map. It’s great for following race progress, but it mostly serves as a tool for someone you rely on to know your location in case an incident occurs. It has generally worked effectively, although the real location has occasionally lagged when moving in and out of good LTE signal.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, though it is essential to note that satellite service is restricted to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available via the customer service portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled components. Garmin provides recycling schemes 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 plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re without coverage.

Outcome is an even more impressive outdoor device for those that want to be unplugged. If you want to have someone keep an eye on you remotely while running out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

It is very freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to enable the service. Fortunately it is not dependent on your phone carrier so works with any make of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, biking or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, monitors all activities with best-in-class GPS, integrated flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very costly, LTE and satellite features need monthly subscription, limited Garmin Pay financial compatibility, speech capabilities are slow, limited smartwatch functionality versus Apple/Google/Samsung watches.
