Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

The newest iteration of Garmin's top-tier Fenix outdoor watch introduces a potentially lifesaving capability: no-phone communication and emergency alerts via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by adding cutting-edge cellular tech, plus an optional advanced microLED screen in a limited edition. It is the brand's premier model and designed to be the only tool needed to venture virtually any location and monitor all your movements.

That makes it an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £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.

Users receive a lot of features for your money, with industry-leading workout, movement and adventure tracking. Its complete offline mapping of the world can automatically guide you return to the trail if you get lost absent a phone, and appear great on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm size available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as tested does have an additional day of watch battery life despite the screen always active, enduring 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 orbital subscription service rather than depending on a watch plan tied to your phone provider, like other smartwatches. However in contrast to competing satellite-enabled products, SOS communication is not included for free.

Rather, subscriptions start at £7.99 or similar a month, which provides unlimited LTE text and voice messages, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while out running, cycling or comparable pursuits – plus emergency satellite SOS alerts.

Location updates and messages over satellite are then billed on top, with higher-tier plans including various quotas of orbital usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have completed setup, you just head out the door without your phone and the watch will connect to LTE. You can not use it for playing music or comparable activities, but you are able to place and receive calls, send texts and overall keep in touch with your relatives and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then message reciprocally using typed or spoken messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, only a phone number is sufficient to sign up for texts.

Messaging on the watch works fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable canned responses you can use to expedite communication. Spoken messages and calls perform OK, though as with most wearables, you’re not going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the most useful function. You can configure to automatically transmit a URL to selected contacts whenever you begin an exercise, so they can follow your real time position on a map. It’s excellent for monitoring competition progress, but it primarily serves as a utility for someone you trust to know your location in case something happens. It has generally worked effectively, though the actual position has sometimes been delayed when transitioning in and out of strong LTE coverage.

All of these features are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide displays you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to remember that orbital service is limited to the US continent, most of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services available through the customer service site. 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 provides recycling programs on new purchases.

Cost

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

Conclusion

The Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re without coverage.

Outcome is an increasingly remarkable adventure device for those that desire to be phone-free. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without needing anything else.

This is very liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to enable the service. Fortunately it is not dependent on your phone provider so functions with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but still desires to be trackable and reachable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED display, tracks all activities with best-in-class GPS, built-in torch, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Cons: very costly, LTE and orbital functions require ongoing payment, limited Garmin Pay bank compatibility, voice capabilities are slow, limited smartwatch functionality compared with competing watches.
