The Fenix 8 Pro Review: Integrated LTE and Orbital Communication for No-Phone Texting

The newest iteration of Garmin's premium Fenix adventure watch brings a life-saving capability: no-phone messaging and emergency alerts via 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new cellular tech, plus an available advanced microLED display in a special edition. This is the brand's top device and designed to be the single gadget needed to venture almost any location and track every activity.

This makes it an very pricey option, starting at £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 – nearly double the price of the standard Fenix 8.

Users get a significant features for your investment, with industry-leading fitness, movement and adventure monitoring. The full offline maps of the world can seamlessly direct you return to the trail if you get lost absent a phone, and appear great on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as tested does have an additional day of smartwatch battery life even with the screen on all the time, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan tied to your mobile carrier, as with other wearables. But in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for free.

Instead, plans begin from £7.99 or equivalent a month, which provides limitless LTE text and audio messaging, calls and LiveTrack position tracking – so your contacts or loved ones can keep an eye on you while out jogging, biking or similar pursuits – plus SOS satellite SOS alerts.

Check-ins and texts via satellite are then billed additionally, with higher-tier subscriptions including different allowances of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the service.

After you have completed setup, you simply head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, send texts and generally stay connected with your family and friends.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using typed or voice messages, and initiate voice calls. Your contact is not required to have a Garmin profile 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 small on-screen keyboard is slow. It has a set of customisable canned replies you can use to expedite communication. Voice recordings and calls perform acceptably, although as with the majority of wearables, you’re not going to wish to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the handiest function. You can set it up to on its own transmit a URL to selected contacts every time you begin an activity, so they can follow your real time location on a map. It’s excellent for monitoring race performance, but it primarily serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has typically worked effectively, although the real location has occasionally lagged when transitioning in and out of strong LTE coverage.

These features are available on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide displays you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, though it is essential to remember that satellite service is restricted to the US continent, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with services offered via 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 lacks any recycled components. Garmin provides recycling schemes 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).

Conclusion

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

Outcome is an increasingly remarkable outdoor device 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 middle of nowhere, the Garmin does so without needing additional gear.

It is quite liberating to be outdoors without a phone, but that functionality carries quite a price, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to provide the service. Fortunately it is not dependent on your phone carrier so functions with any 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, biking or trekking, but nevertheless wants to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors everything with best-in-class GPS, built-in flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: very costly, LTE and orbital features need monthly payment, limited Garmin Pay bank compatibility, speech capabilities are sluggish, basic wearable features compared with Apple/Google/Samsung watches.
