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

This most recent model of the top-tier Fenix outdoor watch brings a life-saving capability: no-phone messaging and emergency alerts using 4G LTE or orbital links.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile technology, plus an optional advanced microLED screen in a special edition. It is the brand's premier model and designed to be the only gadget needed to explore virtually any location and track all your movements.

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

You do receive a significant functionality for your money, with industry-leading workout, movement and adventure tracking. Its full offline mapping of the globe can automatically guide you return to the path if you lose your way without a phone, and appear excellent on the sizable, sharp and high-luminance touchscreen.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, omitting the more compact 43mm version found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED model as tested does have an extra day of smartwatch battery life despite the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription plan instead of depending on a watch plan linked to your mobile carrier, like other smartwatches. However in contrast to competing satellite-enabled products, emergency communication is not provided for free.

Rather, plans begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack location tracking – so your contacts or family can monitor you while out running, cycling or similar activities – plus SOS orbital SOS messaging.

Check-ins and texts via orbital are then billed additionally, with higher-tier subscriptions including different allowances of satellite use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you simply venture the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you can make and take calls, send texts and generally stay connected with your relatives and friends.

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

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set replies you can use to speed things up. Voice recordings and calls work OK, though as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can configure to on its own transmit a URL to chosen contacts every time you start an activity, so they can track your real time position on a map. It’s excellent for monitoring competition performance, but it mostly serves as a utility for someone you trust to know your location in case an incident occurs. It has generally functioned well, although the actual position has sometimes been delayed when transitioning in and out of good LTE coverage.

These features 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 SOS SOS.

A guide 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 unexpectedly easy to use and could be a crucial safety feature, however it is essential to note that orbital coverage is restricted to the US continent, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services available through the support portal. The battery is certified to maintain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused materials. Garmin offers disposal schemes on recent purchases.

Cost

This 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).

Conclusion

The Fenix 8 Pro takes a fantastic adventure watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of signal.

Outcome is an increasingly impressive outdoor device for those that want to be unplugged. If you wish to have someone monitor you remotely while exercising after dark or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is very liberating to be outdoors without a phone, but that functionality comes at a significant price, both in terms of the colossal price of the watch and the recurring subscription of the inReach plan to provide the features. Fortunately it is not reliant on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still desires to be trackable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, super-bright OLED display, tracks all activities with premier GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and satellite features require ongoing payment, limited Garmin Pay bank compatibility, voice features are sluggish, basic wearable functionality versus competing watches.
