Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Messaging

This latest version of Garmin's flagship Fenix outdoor watch includes a life-saving feature: phone-free communication and emergency alerts via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new mobile technology, plus an available advanced microLED screen in a limited edition. This is Garmin's premier model and designed to be the single tool needed to explore virtually any location and monitor every activity.

That makes it an very pricey option, 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 screen – nearly twice the price of the regular Fenix 8.

Users receive a lot of functionality for your investment, with industry-leading workout, activity and outdoor tracking. The complete offline maps of the globe can automatically guide you back to the trail if you lose your way absent a phone, and look excellent on the sizable, sharp and super-bright display.

This 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 bigger wrists. However the 47mm OLED version as tested does have an additional day of watch battery life despite the display always active, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan tied to your phone provider, as with other wearables. However in contrast to Apple or Google's satellite-capable devices, SOS communication is not included for free.

Instead, subscriptions begin from £7.99 or equivalent a month, which provides unlimited LTE text and voice messages, call functionality and LiveTrack position tracking – so your friends or loved ones can monitor you while engaged in jogging, cycling or comparable activities – plus SOS orbital SOS alerts.

Location updates and messages via satellite are then billed additionally, with higher-tier subscriptions including various quotas of orbital use, increasing to a £50 a month unlimited 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 head out outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or comparable tasks, but you can make and take calls, dispatch texts and overall stay connected with your family and friends.

Whenever you message someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message back and forth via typed or voice messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, just a phone number is sufficient to register for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It has a set of personalizable pre-set replies you can use to speed things up. Spoken messages and calls perform acceptably, although as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is not ideal.

LiveTrack is the most useful function. You can set it up to automatically send a URL to selected contacts every time you start an exercise, so they can follow your live position on a map. It’s great for following competition progress, but it primarily serves as a utility for someone you rely on to know your whereabouts in case something happens. It has typically worked well, though the real position has occasionally lagged when moving in and out of good LTE coverage.

All of these features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance shows you how to find 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 safety feature, though it is essential to note that orbital coverage is restricted to the US continent, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered via the support portal. The battery is certified to retain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused components. Garmin provides disposal programs on new purchases.

Price

This Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive adventure tool for those that desire to be phone-free. If you want to have someone monitor you from afar while running out at night or in the remote areas, the Garmin does so without requiring anything else.

It is very freeing to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach service to enable the features. At least it isn’t dependent on your phone provider so works with all brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, cycling or hiking, but still wants to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED display, tracks all activities with premier GPS, integrated flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: extremely expensive, LTE and orbital functions need ongoing payment, restricted Garmin Pay financial compatibility, speech features are slow, basic wearable features versus competing watches.
