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

This newest iteration of the premium Fenix outdoor timepiece includes a life-saving feature: no-phone messaging and emergency alerts using 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile tech, plus an available advanced microLED screen in a limited edition. This is Garmin's top device and engineered to be the single gadget needed to venture almost any location and track all your movements.

That makes it an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the cost of the regular Fenix 8.

Users receive a lot of features for your money, with best-in-class workout, activity and outdoor tracking. The complete offline mapping of the globe can seamlessly direct you back to the trail if you lose your way without a phone, and look excellent on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm size available in other models, so it is a big watch for larger wrists. However the 47mm OLED model as reviewed boasts an additional day of watch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan tied to your mobile provider, like other smartwatches. But in contrast to competing satellite-enabled devices, emergency messaging is not included for free.

Instead, plans start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while out running, biking or similar activities – along with SOS satellite SOS messaging.

Location updates and messages via satellite are then billed on top, with higher-tier subscriptions including various quotas of orbital use, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the functionality.

After you have got it set up, you just head out outside without your phone and the watch will connect to LTE. You cannot use it for playing music or similar tasks, but you can make and take calls, dispatch texts and generally keep in touch with your relatives and friends.

Whenever you message someone, Garmin dispatches them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth using typed or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, just a phone number is enough to register for texts.

Texting on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of personalizable pre-set replies you can use to expedite communication. Voice recordings and calls perform acceptably, though as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can configure to automatically send a link to selected contacts whenever you start an exercise, so they can follow your real time location on a map. It’s excellent for following competition performance, but it mostly acts as a utility for someone you trust to be aware of your whereabouts in case something happens. It has generally functioned well, although the real location has occasionally lagged when moving in and out of strong 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 orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A guide shows you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is essential to note that orbital service is restricted to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options available through the support site. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin offers disposal 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 fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital messaging, check-in and SOS SOS for when you’re without coverage.

The result is an even more impressive outdoor tool for those that desire to be unplugged. 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 accomplishes this without requiring additional gear.

It is quite liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to provide the service. Fortunately it is not reliant on your phone carrier so functions with any brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or hiking, but still desires to be trackable and contactable. For other users, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and satellite communication, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: very costly, LTE and orbital functions require ongoing payment, restricted Garmin Pay bank support, voice capabilities are sluggish, basic wearable functionality versus Apple/Google/Samsung watches.
