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

The most recent version of the flagship Fenix outdoor timepiece brings a life-saving capability: no-phone communication and emergency alerts using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new mobile tech, plus an available advanced microLED display in a special edition. This is Garmin's premier model and engineered to be the only tool required to venture virtually anywhere and monitor all your movements.

This positions it as an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the price of the regular Fenix 8.

Users receive a lot of features for your investment, with industry-leading fitness, movement and adventure tracking. Its full offline maps of the globe can seamlessly guide you return to the path if you lose your way without a phone, and look excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a big 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, lasting a solid eight to nine days between charges.

No-Phone Texting, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and satellite service service instead of relying on a watch plan tied to your phone provider, like other smartwatches. But in contrast to competing satellite-capable devices, emergency communication is not provided for no cost.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE text and voice messages, calls and LiveTrack position sharing – so your friends or family can keep an eye on you while engaged in jogging, biking or comparable pursuits – plus emergency orbital SOS alerts.

Location updates and messages over satellite are then billed additionally, with higher-tier subscriptions including various quotas of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the functionality.

After you have completed setup, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable tasks, but you can make and take calls, send texts and generally stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally using text or spoken messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, just a mobile number is enough to sign up for texts.

Messaging on the watch functions fine but composing texts on the small on-screen keyboard is slow. It includes a set of personalizable canned replies you can send to speed things up. Spoken messages and calls perform acceptably, though as with the majority of smartwatches, you’re not going to want to use it for extended discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can set it up to automatically send a link to chosen contacts whenever you begin an activity, so they can track your real time position on a map. It’s excellent for monitoring race progress, but it primarily acts as a tool for someone you rely on to know your whereabouts in case something happens. It has generally worked effectively, although the actual location has sometimes lagged when transitioning in and out of strong LTE signal.

All of these features are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is important to remember that orbital coverage is restricted to the US continent, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options offered via the customer service portal. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any reused components. Garmin provides disposal programs on recent 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 subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re without coverage.

The result is an increasingly impressive outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

This is quite liberating 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 service to provide the service. At least it isn’t dependent on your phone carrier so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, cycling or hiking, but nevertheless wants to be trackable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED screen, monitors all activities with best-in-class GPS, built-in torch, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Drawbacks: very expensive, LTE and satellite features require ongoing subscription, restricted Garmin Pay bank compatibility, voice features are sluggish, basic wearable functionality versus competing watches.
