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

The most recent version of Garmin's premium Fenix outdoor timepiece brings a potentially lifesaving capability: no-phone communication and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding cutting-edge cellular technology, plus an optional state-of-the-art microLED display in a special edition. This is Garmin's top device and engineered to be the only tool needed to venture almost any location and monitor all your movements.

This positions it as an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the cost of the standard Fenix 8.

You do get a significant functionality for your money, with best-in-class workout, activity and outdoor monitoring. Its full offline mapping of the world can seamlessly direct you return to the trail if you lose your way absent a phone, and look great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 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 extra day of smartwatch battery life even with the display on all the time, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

The company uses its proprietary inReach LTE (4G) and satellite service plan rather than depending on a watch plan tied to your mobile provider, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled products, SOS communication is not included for free.

Rather, plans begin from £7.99 or equivalent a month, which provides limitless LTE text and voice messaging, calls and LiveTrack position sharing – so your contacts or loved ones can keep an eye on you while out running, cycling or comparable pursuits – plus SOS satellite SOS messaging.

Check-ins and messages via satellite are then charged additionally, with higher-tier plans including different quotas of satellite use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can evaluate the functionality.

Once you have completed setup, you simply head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you can place and receive calls, dispatch texts and generally keep in touch with your family and friends.

When you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via text or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, only a mobile number is sufficient to register for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable canned responses you can use to expedite communication. Voice messages and calls perform acceptably, although as with most wearables, you’re not going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the most useful function. You can set it up to on its own send a link to selected contacts whenever you start an activity, so they can track your live position on a map. It’s great for following competition performance, but it mostly acts as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has typically functioned effectively, although the real position has sometimes lagged when moving in and out of strong LTE coverage.

These capabilities are available 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, position 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 unexpectedly easy to use and could be a vital lifeline, however it is essential to remember that satellite service is restricted to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available through the customer service site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin provides recycling schemes on new purchases.

Price

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service plans begin 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 messaging, call functionality and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re out of coverage.

The result is an even more remarkable adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin does so without requiring anything else.

It is quite liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to enable the service. At least it isn’t dependent on your phone provider so works with any make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but still desires to be locatable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital communication, super-bright OLED display, tracks everything with premier GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: very costly, LTE and satellite features require monthly payment, restricted Garmin Pay financial support, voice capabilities are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
