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

This latest model of Garmin's flagship Fenix adventure timepiece includes a life-saving capability: phone-free messaging and SOS alerts using 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding cutting-edge mobile technology, along with an optional advanced microLED screen in a limited edition. It is the brand's top device and designed to be the only tool needed to explore almost any location and monitor all your movements.

This makes it an extremely expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – almost double the price of the standard Fenix 8.

Users get a significant functionality for your money, with industry-leading fitness, activity and adventure monitoring. Its full offline maps of the world can seamlessly guide you back to the path if you get lost absent a phone, and appear great on the sizable, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed does have an additional day of watch battery life even with the screen on all the time, enduring a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service instead of relying on a watch plan linked to your phone carrier, as with other wearables. But in contrast to Apple or Google's satellite-capable devices, emergency communication is not included for no cost.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE text and audio messages, calls and LiveTrack location sharing – so your friends or family can monitor you while out running, biking or similar pursuits – along with emergency satellite SOS alerts.

Check-ins and messages via satellite are then charged on top, with higher-tier plans including different quotas of orbital use, climbing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you just venture the door without your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you can make and take calls, send texts and overall keep in touch with your relatives and companions.

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 download the Garmin Messenger app, you can then message reciprocally via text or voice messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, only a mobile number is enough to register for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It has a collection of personalizable pre-set replies you can send to speed things up. Spoken messages and calls perform OK, although as with most smartwatches, you’re not going to want to use it for extended discussions as the quality is not ideal.

LiveTrack is the handiest feature. You can configure to on its own transmit a link to chosen contacts every time you begin an activity, so they can track your live location on a map. It’s excellent 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 typically functioned effectively, although the actual position has sometimes been delayed when transitioning in and out of strong LTE coverage.

These features are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide shows you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, however it is essential to remember that orbital service is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with services available through the support site. The battery is rated to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides disposal schemes on new purchases.

Cost

This 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

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite messaging, location update and SOS SOS for when you’re out of coverage.

Outcome is an increasingly remarkable outdoor 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 quite liberating to be outside without a phone, but that functionality comes at a significant price, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to provide the features. Fortunately it is not dependent on your phone carrier so works with any brand of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who dislikes being burdened by their phone when jogging, biking or hiking, but still desires to be trackable and contactable. For other users, it is a significant expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: very costly, LTE and satellite features require monthly subscription, restricted Garmin Pay financial compatibility, speech capabilities are sluggish, limited smartwatch features compared with Apple/Google/Samsung watches.
