Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Messaging

The most recent model of the top-tier Fenix outdoor timepiece brings a potentially lifesaving capability: phone-free messaging and emergency alerts using 4G LTE or orbital links.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by incorporating cutting-edge cellular technology, along with an available advanced microLED screen in a limited edition. It is Garmin's top device and designed to be the single gadget needed to explore almost anywhere and monitor all your movements.

This makes it an very expensive proposition, 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 screen – nearly double the cost of the regular Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class workout, activity and adventure tracking. The complete offline mapping of the world can seamlessly direct you return to the trail if you lose your way absent a phone, and look great on the large, sharp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm version found in other models, so it is a large watch for larger wrists. However the 47mm OLED version as tested boasts an additional day of watch battery life despite the screen always active, enduring a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital service plan rather than relying on a watch plan tied to your phone provider, as with other wearables. However in contrast to Apple or Google's satellite-enabled products, emergency communication is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE SMS and audio messages, calls and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while engaged in jogging, cycling or comparable activities – plus SOS satellite SOS messaging.

Location updates and texts via satellite are then charged on top, with more expensive plans offering different quotas of orbital use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the service.

After you have completed setup, you simply venture outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you can make and take calls, send texts and overall stay connected with your relatives and friends.

When you text 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 reciprocally via typed or spoken messages, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a phone number is enough to register for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable canned replies you can use to expedite communication. Voice messages and calls perform acceptably, although as with most smartwatches, you’re not going to wish to use it for lengthy discussions as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can set it up to automatically send a link to chosen contacts every time you start an activity, so they can follow your live location on a map. It’s excellent for monitoring competition progress, but it mostly serves as a tool for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally functioned effectively, though the real location has occasionally 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 locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance shows you how to find the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is essential to remember that satellite service is restricted to the US continent, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options offered via the support portal. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin provides recycling schemes on new 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

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

Outcome is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin does so without needing anything else.

This is quite liberating to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal price of the watch and the recurring subscription of the inReach service to provide the service. Fortunately it isn’t dependent on your phone provider so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, biking or trekking, but nevertheless desires to be locatable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, monitors everything with premier GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: extremely expensive, LTE and satellite features require monthly payment, limited Garmin Pay bank support, speech capabilities are sluggish, limited smartwatch features versus competing watches.
