Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

The latest version of the premium Fenix adventure watch includes a potentially lifesaving feature: no-phone communication and SOS messaging using 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating cutting-edge cellular technology, along with an available state-of-the-art microLED display in a special edition. This is the brand's top model and designed to be the single gadget required to venture almost anywhere and monitor every activity.

This makes it an extremely pricey option, 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 edition with microLED display – nearly twice the price of the regular Fenix 8.

You do receive a significant features for your money, with industry-leading workout, activity and adventure tracking. Its full offline mapping of the world can automatically guide you return to the trail if you get lost without a phone, and appear excellent on the large, crisp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as tested boasts an additional day of watch battery life even with the screen always active, lasting a solid eight to nine days between charging.

No-Phone Texting, Calls and Real-Time Location

The company operates its own inReach LTE (4G) and satellite service service instead of relying on a watch plan tied to your mobile carrier, like other smartwatches. But unlike Apple or Google's satellite-capable products, SOS messaging is not provided for free.

Rather, subscriptions begin from £7.99 or similar a month, which provides unlimited LTE text and audio messages, calls and LiveTrack position sharing – so your contacts or family can monitor you while engaged in jogging, biking or similar pursuits – plus emergency orbital SOS alerts.

Location updates and messages via satellite are then billed additionally, with more expensive plans offering various quotas of orbital use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the service.

After you have completed setup, you simply venture outside minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable tasks, but you are able to make and take calls, send texts and generally keep in touch with your family and companions.

When you text 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 message back and forth using text or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a mobile number is enough to sign up for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can use to expedite communication. Voice recordings and calls perform OK, although as with the majority of wearables, you’re not going to wish to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can set it up to on its own transmit a URL to selected contacts every time you start an exercise, so they can follow your real time location on a map. It’s great for monitoring race progress, but it mostly acts as a tool for someone you trust to be aware of your location in case something happens. It has generally functioned effectively, though the real location has occasionally lagged when moving in and out of strong LTE signal.

These capabilities are available on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to remember that satellite service is limited to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with options available via the support portal. 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 components. Garmin offers recycling schemes on recent 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 packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly remarkable adventure device for those that want to be phone-free. If you want to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is quite freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach service to provide the service. Fortunately it is not dependent on your phone carrier so works with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and reachable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, high-luminance OLED screen, tracks all activities with premier GPS, built-in flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and satellite functions need ongoing subscription, restricted Garmin Pay bank support, speech capabilities are slow, basic smartwatch features compared with competing watches.
