The Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Messaging

The most recent version of the premium Fenix adventure timepiece introduces a life-saving feature: phone-free messaging and emergency alerts via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by adding new cellular tech, along with an optional state-of-the-art microLED screen in a limited edition. This is Garmin's premier model and designed to be the only tool required to venture almost any location and monitor all your movements.

That positions it as an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the price of the regular Fenix 8.

You do get a lot of features for your investment, with best-in-class fitness, activity and adventure monitoring. Its full offline mapping of the world can automatically guide you return to the trail if you get lost without a phone, and look great on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm size found in other models, so it is a large watch for larger wrists. However the 47mm OLED model as tested boasts an extra day of smartwatch battery life even with the screen always active, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan tied to your phone provider, like other smartwatches. But in contrast to Apple or Google's satellite-capable products, SOS communication is not provided for free.

Rather, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or family can monitor you while out running, cycling or comparable pursuits – plus emergency satellite SOS alerts.

Check-ins and messages over satellite are then charged additionally, with more expensive subscriptions including different quotas of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just head out the door without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, send texts and overall stay connected with your relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then communicate back and forth using typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a mobile number is enough to register for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It has a set of personalizable pre-set replies you can use to expedite communication. Spoken messages and calls work OK, although as with the majority of wearables, you’re unlikely going to wish to use it for extended conversations as the quality is not ideal.

LiveTrack is the most useful function. You can set it up to on its own transmit a link to chosen contacts whenever you begin an activity, so they can follow your live position on a map. It’s excellent for following competition progress, but it primarily serves as a tool for someone you trust to know your location in case an incident occurs. It has generally worked effectively, although the real location has sometimes been delayed when transitioning in and out of good LTE coverage.

All of these features are accessible on other Garmin watches 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 send texts, position updates and SOS SOS.

A guide displays you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, however it is important to remember that satellite service is restricted to the US continent, most of Canada, and the majority of Europe except for regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with options available via the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin provides recycling programs on new purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans begin 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 messaging, call functionality and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly remarkable outdoor tool for those that want to be phone-free. If you wish to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is very freeing to be outdoors without a phone, but that capability carries a significant price, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to provide the service. Fortunately it isn’t dependent on your phone carrier so works with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, biking or trekking, but still desires to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with premier GPS, built-in flashlight, voice and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite features need monthly payment, limited Garmin Pay bank compatibility, voice features are slow, limited wearable functionality compared with Apple/Google/Samsung watches.
