Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

The newest version of the premium Fenix adventure timepiece brings a potentially lifesaving feature: phone-free communication and emergency alerts using 4G LTE or satellite links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge cellular tech, along with an available state-of-the-art microLED screen in a special edition. It is the brand's top model and designed to be the single tool needed to venture virtually anywhere and track all your movements.

This makes it an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the cost of the regular Fenix 8.

Users receive a lot of features for your money, with best-in-class fitness, activity and adventure monitoring. The complete offline mapping of the world can automatically guide you return to the path if you get lost absent a phone, and look great on the sizable, sharp and high-luminance touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm version found in other devices, so it is a large watch for larger 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 reliable eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription plan rather than depending on a watch plan linked to your phone provider, as with other smartwatches. However unlike Apple or Google's satellite-enabled products, emergency communication is not provided for free.

Rather, subscriptions start at £7.99 or equivalent a month, which includes limitless LTE text and voice messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in jogging, biking or comparable activities – plus emergency orbital SOS messaging.

Check-ins and messages via orbital are then billed on top, with more expensive plans including various quotas of satellite use, increasing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the service.

Once you have completed setup, you simply venture outside without your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you are able to place and receive calls, dispatch texts and overall keep in touch with your family and companions.

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

Texting on the watch works fine but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable pre-set replies you can use to speed things up. Voice recordings and calls perform OK, though as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to on its own send a URL to selected contacts every time you begin an exercise, so they can track your live location on a map. It’s great for monitoring competition progress, but it primarily serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has typically worked effectively, though the actual position has sometimes been delayed when moving in and out of strong LTE signal.

These features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance shows you how to find the clear view to the orbital system, which then sends and receives 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 remember that orbital coverage is restricted to the US continent, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options available via the support portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused materials. Garmin provides disposal programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital communication, check-in and SOS SOS for when you’re without signal.

Outcome is an even more remarkable adventure device for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to enable the features. Fortunately it is not reliant on your phone provider so functions with all make of smartphone and carrier.

This 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 locatable and reachable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED screen, tracks everything with premier GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and satellite features require ongoing subscription, limited Garmin Pay financial compatibility, voice features are sluggish, limited wearable features versus competing watches.
