Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for No-Phone Texting

This newest model of the flagship Fenix adventure watch introduces a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating new cellular tech, plus an available advanced microLED screen in a special edition. This is the brand's premier device and engineered to be the single tool needed to explore virtually any location and track every activity.

This positions it as an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the cost of the regular Fenix 8.

Users get a lot of functionality for your investment, with best-in-class fitness, activity and outdoor tracking. Its full offline mapping of the world can automatically direct you back to the path if you get lost without a phone, and look excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other models, so it is a big watch for bigger wrists. However the 47mm OLED model as tested boasts an extra day of smartwatch battery life despite the display always active, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan tied to your mobile provider, as with other smartwatches. But unlike Apple or Google's satellite-enabled products, SOS messaging is not included for no cost.

Rather, plans start at £7.99 or similar a month, which includes unlimited LTE text and audio messaging, calls and LiveTrack location sharing – so your contacts or family can keep an eye on you while engaged in running, biking or comparable pursuits – plus SOS orbital SOS alerts.

Check-ins and texts over satellite are then billed additionally, with higher-tier plans including various allowances of orbital usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the service.

After you have completed setup, you just venture the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, dispatch texts and overall keep in touch with your family and companions.

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

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of customisable pre-set responses you can send to expedite communication. Voice messages and calls perform OK, though as with the majority of smartwatches, you’re not going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the handiest function. You can configure to automatically 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 competition performance, but it mostly serves as a tool for someone you rely on to be aware of your location in case something happens. It has generally worked well, although the actual position has sometimes been delayed when moving in and out of good LTE signal.

All of these capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location check-ins and SOS SOS.

A guide shows you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to remember that satellite service is restricted to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services offered through the customer service portal. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal schemes on recent purchases.

Price

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

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re without coverage.

Outcome is an even more remarkable adventure device for those that want to be phone-free. If you want to have someone keep an eye on you from afar while running after dark or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to enable the service. At least it isn’t dependent on your phone provider so works with any make of smartphone and carrier.

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

Pros: LTE and orbital communication, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: extremely expensive, LTE and satellite functions require monthly payment, restricted Garmin Pay financial compatibility, voice capabilities are sluggish, basic wearable features versus Apple/Google/Samsung watches.
