Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

The most recent iteration of Garmin's premium Fenix outdoor watch brings a life-saving capability: no-phone communication and SOS alerts using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge mobile tech, plus an optional state-of-the-art microLED display in a special edition. This is Garmin's top device and engineered to be the single gadget required to venture virtually any location and monitor every activity.

This makes it an very expensive option, priced from £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 cost of the standard Fenix 8.

Users get a significant functionality for your money, with industry-leading workout, movement and outdoor tracking. The full offline mapping of the globe can seamlessly direct you return to the trail if you get lost without a phone, and appear excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm version available in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as tested does have an additional day of smartwatch battery life even with the screen on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital service service rather than relying on a watch plan tied to your mobile carrier, like other wearables. But in contrast to competing satellite-enabled devices, emergency messaging is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which provides limitless LTE text and audio messages, call functionality and LiveTrack position sharing – so your contacts or family can monitor you while engaged in running, biking or similar activities – plus SOS satellite SOS alerts.

Check-ins and messages over satellite are then charged additionally, with more expensive subscriptions offering different quotas of orbital use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

Once you have completed setup, you simply venture the door minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and friends.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can respond to back to your watch. If they install the Garmin Messenger app, you can then message back and forth using text or voice communications, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger app, just a phone number is enough to register for texts.

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable pre-set replies you can use to expedite communication. Spoken messages and calls work acceptably, though as with most wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can set it up to automatically transmit a link to selected contacts whenever you start an exercise, so they can track your live position on a map. It’s excellent for following race progress, but it mostly acts as a tool for someone you trust to know your location in case an incident occurs. It has generally worked effectively, though the actual position has sometimes been delayed when moving in and out of strong LTE signal.

These capabilities are available on other Garmin devices 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, position check-ins and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, however it is important to remember that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with services available through the support site. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides disposal schemes 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 packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

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

Outcome is an increasingly remarkable outdoor device for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

It is very liberating to be outside without a phone, but that capability comes at quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it isn’t dependent on your phone carrier so works with any brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, biking or hiking, but still desires to be locatable and reachable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, high-luminance OLED display, tracks everything with best-in-class GPS, built-in torch, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely expensive, LTE and orbital features need ongoing payment, restricted Garmin Pay bank support, voice features are slow, basic wearable functionality compared with competing watches.
