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

This newest version of Garmin's top-tier Fenix outdoor timepiece includes a life-saving feature: phone-free communication and emergency alerts using 4G LTE or satellite connections.

The Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating cutting-edge cellular tech, along with an optional state-of-the-art microLED display in a limited edition. This is the brand's premier model and designed to be the single gadget needed to venture almost anywhere and monitor every activity.

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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the cost of the standard Fenix 8.

You do get a significant functionality for your money, with industry-leading workout, activity and adventure monitoring. Its full offline maps of the globe can seamlessly direct you back to the trail if you lose your way without a phone, and appear excellent on the large, crisp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed boasts an extra day of watch battery life despite the screen always active, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite service plan instead of relying on a watch plan tied to your phone carrier, like other wearables. However in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not provided for no cost.

Rather, plans start at £7.99 or similar a month, which provides unlimited LTE SMS and audio messaging, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while engaged in running, biking or similar activities – plus SOS orbital SOS messaging.

Location updates and texts via satellite are then billed additionally, with higher-tier plans including various allowances 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 service.

Once you have got it set up, you simply venture the door without your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you are able to place and receive calls, dispatch texts and overall keep in touch with your family and friends.

When you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via text or spoken messages, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger app, only a mobile number is enough to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a set of personalizable canned replies you can send to expedite communication. Spoken messages and calls work acceptably, although as with the majority of smartwatches, you’re not going to want to use it for lengthy conversations as the quality is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own send a link to selected contacts whenever you start an exercise, so they can track your real time position on a map. It’s excellent for following race performance, but it mostly serves as a utility for someone you trust to know your location in case an incident occurs. It has typically worked well, though the actual position has occasionally been delayed when transitioning in and out of strong LTE coverage.

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

A guide shows you how to locate the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, however it is important to remember that satellite coverage is restricted to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options available through the customer service 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 components. Garmin offers disposal schemes on new 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 plans cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable adventure device for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is quite freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the substantial price of the watch and the recurring fee of the inReach service to provide the features. At least it isn’t dependent on your phone carrier so works with any make of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, biking or trekking, but nevertheless desires to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.
