The Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Texting

This latest model of Garmin's flagship Fenix outdoor watch brings a potentially lifesaving feature: phone-free communication and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new cellular tech, along with an available advanced microLED screen in a limited edition. It is Garmin's top model and designed to be the only tool required to venture almost anywhere and track every activity.

That makes it an extremely pricey 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 cost of the regular Fenix 8.

Users receive a significant functionality for your investment, with best-in-class fitness, activity and adventure monitoring. The full offline maps of the globe can seamlessly guide you back to the trail if you get lost without a phone, and appear great 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 size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as tested boasts an extra day of smartwatch battery life despite the screen always active, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company operates its own inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan linked to your phone provider, like other smartwatches. However unlike Apple or Google's satellite-enabled devices, SOS communication is not provided for free.

Rather, plans begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack location sharing – so your contacts or family can keep an eye on you while out running, cycling or similar activities – plus SOS orbital SOS messaging.

Check-ins and messages over satellite are then charged on top, with more expensive subscriptions including various quotas of orbital 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.

After you have completed setup, you just venture outside without your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via typed or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to register for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It has a set of personalizable canned replies you can use to speed things up. Spoken recordings and calls perform OK, although as with most smartwatches, you’re not going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the most useful feature. You can configure to automatically send a URL to selected contacts every time you begin an activity, so they can follow your live location on a map. It’s excellent for following race performance, but it mostly serves as a tool for someone you trust to be aware of your whereabouts in case something happens. It has typically worked well, though the actual position has occasionally lagged when moving in and out of good LTE signal.

These features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A guide shows you how to find the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, though it is important to note that orbital service is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options offered through the customer service portal. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal schemes on new purchases.

Cost

The Fenix 8 Pro costs 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 excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re out of signal.

The result is an even more impressive outdoor 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 needing anything else.

This is quite freeing to be outside without a phone, but that functionality carries a significant price, both in terms of the substantial price of the watch and the monthly subscription of the inReach plan to enable the service. At least it isn’t reliant on your phone provider so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, cycling or trekking, but nevertheless desires to be trackable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touch.

Cons: extremely costly, LTE and satellite features require monthly payment, restricted Garmin Pay financial support, speech features are sluggish, limited smartwatch features versus competing watches.
