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

The newest version of the premium Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge cellular technology, plus an available state-of-the-art microLED screen in a special edition. It is Garmin's premier model and engineered to be the single gadget needed to explore virtually any location and monitor all your movements.

This positions it as an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly twice the price of the regular Fenix 8.

You do get a significant functionality for your money, with industry-leading fitness, movement and outdoor monitoring. The complete offline maps of the globe can automatically direct you back to the trail if you lose your way absent a phone, and appear great on the sizable, crisp and super-bright display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm size found in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed does have an extra day of watch battery life even with the screen always active, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital service service instead of depending on a watch plan tied to your mobile provider, as with other wearables. However in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not included for free.

Rather, subscriptions begin from £7.99 or similar a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack position tracking – so your contacts or family can keep an eye on you while engaged in jogging, biking or similar pursuits – plus SOS satellite SOS messaging.

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

Once you have got it set up, you simply venture the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you are able to place and receive calls, dispatch texts and overall stay connected with your family 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 download the Garmin Messenger application, you can then communicate back and forth via text or spoken communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a phone number is enough to register for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It includes a set of personalizable canned responses you can use to speed things up. Voice messages and calls work OK, though as with most smartwatches, you’re not going to wish to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the most useful function. You can set it up to automatically send a link to selected contacts whenever you begin an activity, so they can track your real time location on a map. It’s great for following competition performance, but it primarily acts as a utility for someone you trust to know your whereabouts in case an incident occurs. It has generally worked effectively, although the real location has sometimes lagged when moving 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 kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to note that satellite service is limited to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with services available through the support site. The battery is rated to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers recycling programs on new purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without coverage.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

This is very freeing to be outside without a phone, but that capability carries quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the service. At least it isn’t dependent on your phone provider so functions 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, cycling or hiking, but nevertheless wants to be locatable and reachable. For everyone else, it is a significant money when the superb Fenix 8 is already available.

Pros: LTE and satellite messaging, super-bright OLED display, tracks all activities with best-in-class GPS, built-in torch, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: very expensive, LTE and orbital functions require monthly payment, limited Garmin Pay bank support, voice features are slow, limited smartwatch functionality compared with competing watches.
