Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Texting

This most recent version of Garmin's premium Fenix outdoor watch introduces a potentially lifesaving feature: no-phone communication and SOS messaging using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating cutting-edge mobile tech, along with an optional state-of-the-art microLED screen in a special edition. This is Garmin's top model and designed to be the only gadget needed to explore almost anywhere and monitor every activity.

That makes it an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the cost of the standard Fenix 8.

Users receive a lot of functionality for your money, with industry-leading fitness, activity and adventure tracking. Its complete offline maps of the world can automatically direct you back to the trail if you get lost absent a phone, and look excellent on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as tested does have an additional day of smartwatch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calling and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and satellite subscription plan instead of relying on a watch plan tied to your phone provider, as with other smartwatches. However unlike Apple or Google's satellite-capable products, emergency communication is not included for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can monitor you while out running, biking or similar activities – along with emergency orbital SOS alerts.

Check-ins and messages over satellite are then billed on top, with higher-tier plans offering different quotas of orbital usage, increasing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the functionality.

Once you have completed setup, you simply head out the door without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you are able to make and take calls, dispatch texts and generally stay connected with your family and companions.

When you message someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally via typed or voice messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable canned responses you can use to speed things up. Spoken recordings and calls perform acceptably, though as with most wearables, you’re unlikely going to wish to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the handiest function. You can configure to on its own 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 acts as a tool for someone you trust to be aware of your location in case an incident occurs. It has typically functioned well, though the actual location has occasionally lagged when transitioning 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 locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A on-screen assistance shows you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is important to note that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally serviceable with options offered through the support portal. The battery is rated to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin offers disposal schemes on new 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 begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re out of coverage.

The result is an increasingly impressive outdoor tool for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite freeing to be outside without a phone, but that capability carries quite a cost, both in terms of the substantial price of the watch and the monthly subscription of the inReach service to provide the service. At least it isn’t dependent on your phone provider so functions with all brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, biking or hiking, but nevertheless desires to be locatable and reachable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED display, monitors everything with premier GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, buttons and touchscreen.

Cons: very costly, LTE and satellite functions require monthly subscription, restricted Garmin Pay financial support, speech capabilities are slow, limited smartwatch functionality versus Apple/Google/Samsung watches.
