The Fenix 8 Pro Review: Integrated LTE and Orbital Connectivity for No-Phone Messaging

The most recent iteration of Garmin's premium Fenix adventure timepiece includes a potentially lifesaving capability: phone-free communication and emergency messaging via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding cutting-edge cellular tech, along with an available advanced microLED display in a special edition. This is Garmin's top model and designed to be the only tool required to venture virtually anywhere and track all your movements.

This positions it as an very expensive 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 – nearly double the cost of the regular Fenix 8.

Users get a lot of functionality for your investment, with industry-leading workout, activity and outdoor monitoring. Its complete offline maps of the globe can seamlessly guide you back to the path if you lose your way without a phone, and look great on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the more compact 43mm version found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as tested does have an extra day of smartwatch battery life despite the display on all the time, enduring a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and orbital service plan rather than depending on a watch plan tied to your mobile provider, like other wearables. But in contrast to Apple or Google's satellite-enabled products, emergency communication is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which provides limitless LTE text and audio messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can monitor you while out jogging, biking or comparable pursuits – plus emergency satellite SOS messaging.

Location updates and texts over satellite are then charged additionally, with more expensive plans offering different quotas of orbital use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the service.

Once you have completed setup, you just venture the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you can place and receive calls, dispatch texts and generally stay connected with your family and companions.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally using text or spoken communications, and make voice calls. Your contact 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 functions fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set replies you can use to expedite communication. Spoken messages and calls perform acceptably, though as with most smartwatches, you’re not going to wish to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to selected contacts whenever you start an exercise, so they can follow your real time position on a map. It’s great for monitoring competition progress, but it primarily acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally worked well, although the actual position has occasionally been delayed when moving in and out of strong LTE signal.

All of these features are available on other Garmin devices 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, position check-ins and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, though it is important to remember that satellite coverage is limited to the US continent, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally serviceable with services available through the support site. The battery is certified to retain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused components. Garmin offers recycling schemes on recent purchases.

Price

This Fenix 8 Pro costs 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 builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re without coverage.

The result is an even more impressive adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you remotely while running out at night or in the remote areas, the Garmin does so without requiring anything else.

This is quite liberating to be outside without a phone, but that capability carries quite a price, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone carrier so functions with all brand of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, biking or hiking, but still wants to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED display, monitors everything with best-in-class GPS, integrated torch, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite features need monthly payment, limited Garmin Pay financial compatibility, voice capabilities are slow, basic wearable functionality versus Apple/Google/Samsung watches.
