The Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for Phone-Free Texting

This latest version of the top-tier Fenix adventure timepiece includes a life-saving feature: phone-free communication and SOS messaging using 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge cellular technology, plus an available state-of-the-art microLED display in a limited edition. This is the brand's top model and engineered to be the only tool required to venture almost any location and track every activity.

That 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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the standard Fenix 8.

Users get a lot of functionality for your investment, with industry-leading fitness, movement and adventure tracking. Its complete offline mapping of the globe can automatically direct you return to the trail if you get lost without a phone, and appear excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the display on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite service plan instead of relying on a watch plan tied to your mobile provider, as with other wearables. But unlike Apple or Google's satellite-capable products, SOS messaging is not provided for no cost.

Instead, plans start at £7.99 or similar a month, which provides unlimited LTE SMS and voice messaging, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in running, cycling or similar activities – along with SOS satellite SOS messaging.

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

After 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 relatives and friends.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate 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 application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable canned replies you can send to expedite communication. Spoken recordings and calls work OK, although as with most wearables, you’re not going to want to use it for extended conversations as the quality is not fantastic.

LiveTrack is the most useful feature. You can set it up to automatically transmit a link to chosen contacts every time you begin an activity, so they can follow your live location 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 location in case an incident occurs. It has generally worked effectively, although the real position has occasionally been delayed when moving in and out of good LTE signal.

These capabilities are available on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate 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 note that satellite service is limited to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with services offered through the support site. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers disposal schemes on new purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re out of signal.

Outcome is an even more remarkable outdoor device for those that desire to be phone-free. If you want to have someone monitor you from afar while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

It is very liberating to be outside without a phone, but that capability comes at a significant price, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to provide the service. At least it isn’t reliant on your phone provider so works with any brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, biking or hiking, but nevertheless wants to be locatable and contactable. For other users, it is a significant expense when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: extremely expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay bank compatibility, voice capabilities are slow, limited wearable features compared with competing watches.
