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

The most recent iteration of Garmin's flagship Fenix adventure timepiece includes a life-saving capability: no-phone communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by adding new cellular tech, plus an available state-of-the-art microLED display in a limited edition. This is Garmin's top model and engineered to be the single tool needed to venture almost any location and monitor all your movements.

That makes it an very pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost twice the cost of the standard Fenix 8.

Users get a lot of functionality for your money, with best-in-class fitness, movement and outdoor tracking. Its full offline maps of the globe can seamlessly guide you back to the trail if you get lost without a phone, and look great on the sizable, crisp and super-bright display.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other devices, so it is a big watch for larger wrists. However the 47mm OLED model as tested does have an extra 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 Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan linked to your phone carrier, as with other smartwatches. However in contrast to Apple or Google's satellite-enabled devices, emergency communication is not provided for no cost.

Instead, plans start at £7.99 or similar a month, which includes limitless LTE text and audio messages, calls and LiveTrack location sharing – so your friends or family can monitor you while out jogging, cycling or comparable pursuits – along with SOS orbital SOS messaging.

Location updates and texts via satellite are then charged on top, with more expensive subscriptions including different quotas of orbital use, climbing to a £50 a month all-inclusive 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 without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, send texts and generally keep in touch with your relatives and friends.

When you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally via text or spoken communications, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, just a phone number is sufficient to sign up for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable canned replies you can use to expedite communication. Spoken recordings and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can configure to on its own transmit a link to chosen contacts whenever you begin an exercise, so they can track your real time position on a map. It’s excellent for monitoring competition progress, but it primarily serves as a tool for someone you rely on to be aware of your location in case something happens. It has generally worked effectively, though the real location has occasionally been delayed when transitioning in and out of strong LTE coverage.

All of these capabilities are accessible on other Garmin devices if you bring your phone with you, but in areas where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, however it is essential to remember that orbital coverage is limited to the US continent, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally serviceable with services offered via the support portal. The battery is rated to retain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin provides recycling programs on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite messaging, location update and emergency SOS for when you’re out of signal.

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

This is quite liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the monthly fee of the inReach plan to provide the service. At least it isn’t reliant on your phone carrier so functions with all make 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, cycling or hiking, but nevertheless wants to be trackable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, monitors everything with premier GPS, integrated torch, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: extremely costly, LTE and satellite functions need monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are sluggish, basic smartwatch functionality compared with Apple/Google/Samsung watches.
