Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Texting

This latest model of the top-tier Fenix adventure timepiece brings a potentially lifesaving capability: no-phone messaging and SOS messaging using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new cellular tech, along with an available state-of-the-art microLED screen in a special edition. It is the brand's top model and engineered to be the only gadget required to venture virtually any location and track every activity.

This positions it as an very pricey proposition, priced from £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 screen – almost twice the price of the standard Fenix 8.

You do get a significant features for your money, with best-in-class fitness, activity and adventure monitoring. Its complete offline maps of the globe can seamlessly direct you back to the trail if you get lost without a phone, and look excellent on the large, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed boasts an extra day of watch battery life despite the display always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital service plan instead of relying on a watch plan tied to your phone carrier, as with other wearables. But unlike competing satellite-capable products, SOS messaging is not included for no cost.

Rather, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE text and audio messaging, calls and LiveTrack position sharing – so your friends or loved ones can monitor you while out jogging, biking or comparable activities – plus emergency orbital SOS messaging.

Check-ins and messages over satellite are then billed additionally, with higher-tier plans including different allowances of orbital use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After you have got it set up, you simply head out outside without your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, dispatch texts and generally keep in touch with your family and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or voice messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, only a phone number is sufficient to register for texts.

Messaging on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable canned replies you can use to speed things up. Voice messages and calls perform OK, though as with most wearables, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to automatically transmit a URL to chosen contacts whenever you begin an activity, so they can follow your real time location on a map. It’s great for following competition progress, but it mostly acts as a utility for someone you rely on to know your location in case an incident occurs. It has typically functioned effectively, although the real location has sometimes lagged when moving in and out of strong LTE coverage.

These capabilities are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance displays you how to locate 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 vital safety feature, however it is important to remember that orbital service is restricted to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services offered via the customer service site. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused materials. Garmin provides recycling schemes on new purchases.

Cost

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

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an even more impressive outdoor tool for those that want to be phone-free. If you want to have someone monitor you remotely while running after dark or in the remote areas, the Garmin does so without requiring additional gear.

It is quite freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to provide the service. Fortunately it isn’t reliant on your phone provider so works with all make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when running, cycling or hiking, but nevertheless wants to be trackable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated torch, voice and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: very costly, LTE and orbital features need monthly subscription, restricted Garmin Pay financial support, speech features are sluggish, basic smartwatch features compared with competing watches.
