Garmin Fenix 8 Pro Review: Integrated LTE and Orbital Communication for Phone-Free Texting

This most recent model of the premium Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or orbital links.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by adding new mobile technology, plus an optional state-of-the-art microLED screen in a special edition. This is the brand's premier model and designed to be the single gadget required to explore virtually any location and monitor every activity.

This makes it an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the price of the standard Fenix 8.

You do get a significant functionality for your money, with best-in-class fitness, activity and adventure monitoring. The full offline mapping of the world can automatically direct you back to the trail if you lose your way without a phone, and appear great on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other models, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed does have an additional day of smartwatch battery life despite the display always active, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and satellite service service instead of relying on a watch plan tied to your phone carrier, as with other smartwatches. But unlike Apple or Google's satellite-capable products, SOS communication is not provided for no cost.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and voice messaging, call functionality and LiveTrack location sharing – so your contacts or family can keep an eye on you while engaged in running, cycling or comparable pursuits – along with SOS satellite SOS alerts.

Location updates and messages via satellite are then charged additionally, with higher-tier subscriptions offering various allowances of satellite usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have completed setup, you simply head out outside without your phone and the watch will link to LTE. You cannot use it for playing music or comparable tasks, but you are able to make and take calls, dispatch texts and overall keep in touch with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message reciprocally via text or spoken communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a phone number is sufficient to register for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned replies you can send to expedite communication. Voice recordings and calls perform OK, although as with most smartwatches, you’re unlikely going to want to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the most useful feature. You can set it up to on its own transmit a link to chosen contacts whenever you start an activity, so they can follow your real time position on a map. It’s excellent for following race performance, but it mostly serves as a tool for someone you trust to know your location in case something happens. It has typically worked effectively, although the actual position has occasionally been delayed when transitioning in and out of strong LTE signal.

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 activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide displays you how to find the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital safety feature, however it is essential to note that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with options available through the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused materials. Garmin provides recycling schemes on new purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

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

The result is an increasingly impressive adventure device for those that want 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 needing additional gear.

It is very freeing to be outside without a phone, but that functionality comes at a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to enable the service. Fortunately it is not reliant on your phone carrier so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, biking or trekking, but still wants to be locatable and contactable. For everyone else, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED screen, tracks all activities with premier GPS, integrated torch, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: very costly, LTE and satellite features require ongoing subscription, limited Garmin Pay bank compatibility, voice features are sluggish, limited smartwatch features versus competing watches.
