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

The newest iteration of the flagship Fenix adventure watch includes a life-saving capability: no-phone communication and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro enhances the previously impressive Fenix 8 by adding cutting-edge cellular technology, plus an available advanced microLED display in a special edition. This is Garmin's premier device and engineered to be the only gadget required to venture almost any location and track all your movements.

This positions it as an very expensive option, priced from £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 display – almost twice the price of the regular Fenix 8.

You do receive a significant features for your investment, with best-in-class workout, activity and outdoor monitoring. The full offline maps of the globe can automatically direct you return to the trail if you get lost without a phone, and look great on the sizable, crisp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the more compact 43mm size found in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as tested does have an extra day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

No-Phone Texting, Calls and Real-Time Location

The company uses its proprietary inReach LTE (4G) and orbital service service rather than depending on a watch plan linked to your mobile provider, like other smartwatches. But unlike Apple or Google's satellite-capable devices, emergency messaging is not included for free.

Rather, plans start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack position sharing – so your contacts or loved ones can keep an eye on you while engaged in running, cycling or comparable pursuits – along with emergency satellite SOS messaging.

Location updates and messages over orbital are then charged additionally, with higher-tier plans offering various quotas of satellite use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the functionality.

Once you have got it set up, you simply venture outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you are able to make and take calls, dispatch texts and generally stay connected with your family and friends.

When you text someone, Garmin dispatches them an SMS from a random number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via text or spoken communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable canned replies you can use to expedite communication. Voice messages and calls perform OK, though as with most wearables, you’re not going to want to use it for extended discussions as the quality is not fantastic.

LiveTrack is the most useful feature. You can configure to on its own send a link to selected contacts whenever you start an exercise, so they can track your real time position on a map. It’s great for monitoring race performance, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically worked well, although the actual location has occasionally lagged when moving in and out of strong LTE signal.

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

A on-screen assistance 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 straightforward to use and could be a vital lifeline, however it is essential to note that satellite coverage is limited to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally repairable with options available via the customer service site. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled components. Garmin offers recycling 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 service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital communication, location update and SOS SOS for when you’re out of coverage.

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

It is very freeing to be outside without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to provide the service. At least it is not reliant on your phone carrier so works with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who hates being weighed down by their phone when running, biking or trekking, but still wants to be trackable and contactable. For other users, it is a significant money when the superb Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, integrated flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Drawbacks: very expensive, LTE and orbital features require monthly payment, restricted Garmin Pay financial support, speech capabilities are slow, basic wearable functionality compared with competing watches.
