Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Texting

The most recent version of Garmin's flagship Fenix adventure timepiece brings a potentially lifesaving feature: no-phone messaging and emergency alerts using 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile technology, along with an optional advanced microLED screen in a limited edition. This is Garmin's top model and designed to be the single tool needed to explore virtually any location and track every activity.

That makes it an very pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly twice the price of the regular Fenix 8.

You do receive a lot of functionality for your money, with industry-leading fitness, movement and outdoor monitoring. The complete offline maps of the globe can automatically direct you back to the path if you lose your way absent 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 sizes, not the more compact 43mm version available in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital service plan instead of relying on a watch plan linked to your mobile carrier, like other wearables. However unlike competing satellite-capable devices, emergency communication is not provided for free.

Rather, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and voice messaging, call functionality and LiveTrack position sharing – so your friends or loved ones can keep an eye on you while out running, biking or similar activities – plus SOS orbital SOS alerts.

Location updates and texts via orbital are then charged on top, with higher-tier subscriptions offering different allowances of orbital usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you just head out the door without your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you can place and receive calls, dispatch texts and generally stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message back and forth using text or voice messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger app, just a mobile number is enough to sign up for texts.

Messaging on the watch functions adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can send to expedite communication. Spoken recordings and calls work OK, though as with the majority of smartwatches, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can configure to automatically transmit a link to selected contacts every time you begin an activity, so they can follow your live position on a map. It’s excellent for following race progress, but it mostly acts as a tool for someone you trust to know your location in case something happens. It has generally functioned effectively, though the actual position has occasionally lagged when transitioning in and out of good LTE coverage.

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

A on-screen assistance displays you how to locate the clear view to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is essential to note that satellite service is limited to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically repairable with services available via the support portal. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides recycling programs on new purchases.

Cost

This Fenix 8 Pro costs 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

The Fenix 8 Pro takes a fantastic adventure watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without signal.

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.

This is quite liberating to be outdoors without a phone, but that capability carries quite a price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it isn’t reliant on your phone provider so works with all brand of smartphone and network.

The Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, biking or hiking, but still desires to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED screen, monitors all activities with best-in-class GPS, built-in flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, basic smartwatch functionality compared with Apple/Google/Samsung watches.
