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

The latest iteration of the top-tier Fenix outdoor timepiece introduces a life-saving capability: no-phone communication and SOS messaging using 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an optional advanced microLED screen in a limited edition. It is Garmin's premier device and designed to be the only gadget needed to explore almost any location and monitor every activity.

This makes it an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the cost of the regular Fenix 8.

Users get a significant features for your investment, with best-in-class fitness, movement and adventure tracking. The complete offline mapping of the globe can automatically direct you back to the path if you get lost absent a phone, and look great on the sizable, crisp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed boasts an extra day of watch battery life even with the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

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

Rather, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messaging, call functionality and LiveTrack position tracking – so your contacts or family can monitor you while out running, cycling or comparable pursuits – along with SOS satellite SOS messaging.

Check-ins and texts via orbital are then charged additionally, with more expensive subscriptions including various allowances of orbital use, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just venture the door without your phone and the watch will connect to LTE. You can not use it for streaming music or similar activities, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and friends.

When you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or voice messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, only a phone number is enough to register for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set replies you can send to speed things up. Voice messages and calls perform OK, although as with the majority of smartwatches, you’re not going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can configure to automatically send a link to chosen contacts whenever you start an activity, so they can track your real time location on a map. It’s great for monitoring race performance, but it primarily serves as a utility for someone you trust to be aware of your location in case an incident occurs. It has generally worked effectively, though the actual location has occasionally been delayed when transitioning in and out of good LTE signal.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A on-screen assistance shows you how to locate the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, however it is important to note that orbital coverage is restricted to the US continent, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available via the support site. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any reused materials. Garmin offers recycling programs on recent 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 begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without signal.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you wish to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is very liberating to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to provide the features. At least it isn’t reliant on your phone carrier so works with any brand of smartphone and carrier.

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

Advantages: LTE and orbital messaging, super-bright OLED display, monitors everything with premier GPS, built-in torch, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touchscreen.

Cons: extremely costly, LTE and satellite features need monthly payment, limited Garmin Pay financial compatibility, speech features are sluggish, basic smartwatch features versus competing watches.
