Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Texting

This most recent model of the premium Fenix outdoor timepiece introduces a potentially lifesaving feature: no-phone communication and SOS alerts via 4G LTE or satellite links.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating new mobile technology, plus an available advanced microLED screen in a limited edition. It is Garmin's top model and designed to be the single gadget required to explore virtually anywhere and monitor all your movements.

This makes it an extremely pricey 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 variant with microLED screen – almost double the price of the regular Fenix 8.

Users get a lot of functionality for your money, with best-in-class fitness, activity and outdoor tracking. Its complete offline mapping of the globe can automatically direct you back to the path if you lose your way absent a phone, and look excellent on the large, crisp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm size available in other models, so it is a big watch for larger wrists. However the 47mm OLED version as tested does have an extra day of watch battery life despite the display always active, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

The company uses its own inReach LTE (4G) and orbital service service rather than depending on a watch plan linked to your phone carrier, as with other wearables. However unlike competing satellite-enabled devices, emergency communication is not provided for no cost.

Instead, plans begin from £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while engaged in running, biking or similar pursuits – plus emergency orbital SOS alerts.

Location updates and messages via satellite are then charged on top, with more expensive plans including various quotas of satellite use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you just head out the door without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you are able to place and receive calls, send texts and overall stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally using text or spoken communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a mobile 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 slow. It includes a collection of personalizable pre-set replies you can use to speed things up. Spoken messages and calls work OK, although as with the majority of smartwatches, you’re not going to wish to use it for extended conversations as the quality is not fantastic.

LiveTrack is the handiest function. You can set it up to automatically send a URL to selected contacts every time you begin an exercise, so they can follow your live position on a map. It’s great for following race progress, but it primarily serves as a utility for someone you trust to be aware of your whereabouts in case something happens. It has typically worked well, although the real location has occasionally lagged when moving in and out of strong LTE signal.

All of these capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance displays you how to find the clear view 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 crucial lifeline, however it is important to remember that satellite coverage is limited to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with options available through the customer service site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides recycling schemes on new purchases.

Cost

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

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite messaging, location update and emergency SOS for when you’re without coverage.

Outcome is an even more impressive outdoor tool for those that want to be unplugged. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is very liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to provide the service. At least 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 burdened by their phone when running, cycling or hiking, but still wants to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, phone and offline voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: extremely expensive, LTE and satellite features require ongoing payment, limited Garmin Pay financial compatibility, voice capabilities are slow, limited wearable features compared with Apple/Google/Samsung watches.
