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

This newest model of the top-tier Fenix outdoor timepiece brings a potentially lifesaving feature: no-phone communication and emergency alerts using 4G LTE or orbital connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by adding new cellular tech, along with an available advanced microLED display in a limited edition. This is the brand's top model and engineered to be the only gadget needed to explore virtually any location and track every activity.

This makes it an extremely expensive option, priced from £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 screen – nearly twice the price of the regular Fenix 8.

Users receive a lot of features for your investment, with best-in-class workout, activity and outdoor monitoring. The full offline maps of the globe can seamlessly direct you return to the path if you lose your way without a phone, and look great on the large, sharp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm version available in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as tested does have an additional day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite subscription service instead of depending on a watch plan linked to your phone provider, like other smartwatches. But in contrast to competing satellite-enabled products, emergency messaging is not included for free.

Instead, subscriptions begin from £7.99 or similar a month, which provides unlimited LTE text and audio messaging, calls and LiveTrack location sharing – so your friends or loved ones can monitor you while engaged in running, cycling or similar activities – along with SOS satellite SOS messaging.

Check-ins and messages over satellite are then billed on top, with more expensive plans including various allowances of satellite usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the service.

Once you have completed setup, you just head out outside minus your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you are able to make and take calls, dispatch texts and generally keep in touch with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally using text or voice 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 sign up for texts.

Texting on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It has a collection of personalizable pre-set responses you can send to expedite communication. Voice recordings and calls perform acceptably, though as with most smartwatches, you’re not going to wish to use it for extended discussions as the quality is not ideal.

LiveTrack is the most useful function. You can configure to automatically transmit a URL to selected contacts every time you start an activity, so they can track your live position on a map. It’s excellent for following race progress, but it mostly acts as a tool for someone you rely on to be aware of your location in case something happens. It has typically functioned effectively, though the actual position has occasionally been delayed when moving in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A guide 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 unexpectedly easy to use and could be a vital safety feature, though it is important to remember that orbital coverage is restricted to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is generally repairable with services available via the support portal. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin offers disposal 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 subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re without coverage.

The result is an even more impressive outdoor device for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring anything else.

It is quite liberating to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the features. At least it isn’t reliant on your phone provider so functions with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, cycling or hiking, but nevertheless desires to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely costly, LTE and orbital features need monthly payment, limited Garmin Pay financial compatibility, voice features are sluggish, basic smartwatch functionality versus competing watches.
