Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Communication for No-Phone Messaging

The latest version of the flagship Fenix adventure watch introduces a potentially lifesaving capability: no-phone communication and emergency alerts using 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new mobile tech, plus an available advanced microLED display in a special edition. It is Garmin's top model and engineered to be the single gadget needed to explore almost any location and track all your movements.

That positions it as an extremely expensive option, 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 variant with microLED display – almost double the price of the regular Fenix 8.

You do get a lot of functionality for your money, with best-in-class workout, movement and outdoor monitoring. Its complete offline mapping of the globe can automatically direct you return to the trail if you get lost absent a phone, and appear excellent on the sizable, crisp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other models, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan tied to your phone provider, as with other smartwatches. However unlike competing satellite-enabled products, emergency communication is not included for free.

Instead, plans begin from £7.99 or similar a month, which includes unlimited LTE text and voice messages, call functionality and LiveTrack location tracking – so your friends or family can monitor you while engaged in jogging, cycling or similar activities – along with emergency satellite SOS messaging.

Check-ins and texts via satellite are then charged on top, with higher-tier subscriptions including different quotas of satellite usage, climbing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you just venture outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you can place and receive calls, dispatch texts and overall stay connected with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message back and forth using text or spoken communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a phone number is sufficient to register for texts.

Texting on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It has a set of customisable pre-set replies you can use to expedite communication. Spoken recordings and calls perform acceptably, although as with most smartwatches, you’re not going to want to use it for extended 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 exercise, so they can follow your live location on a map. It’s great for monitoring race performance, but it mostly acts as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically worked effectively, though the real position has sometimes lagged when transitioning in and out of good LTE signal.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance displays 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 surprisingly easy to use and could be a crucial lifeline, though it is important to remember that orbital service is restricted to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with options offered through 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 recycled components. Garmin offers recycling programs on recent purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re out of signal.

The result is an even more remarkable adventure device for those that desire to be unplugged. If you want to have someone monitor you from afar while running out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is quite liberating to be outside without a phone, but that capability carries quite a cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach service to provide the service. At least it isn’t reliant on your phone carrier so works with all brand of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when running, cycling or trekking, but nevertheless desires to be trackable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED display, tracks everything with premier GPS, integrated torch, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and orbital functions need monthly payment, limited Garmin Pay financial support, speech capabilities are sluggish, basic wearable features versus Apple/Google/Samsung watches.
