Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Communication for Phone-Free Texting

This latest iteration of the top-tier Fenix outdoor timepiece introduces a potentially lifesaving feature: no-phone messaging and emergency alerts using 4G LTE or orbital links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge mobile technology, along with an available advanced microLED display in a limited edition. It is Garmin's premier model and engineered to be the only gadget required to venture almost anywhere and monitor all your movements.

That positions it as an extremely expensive option, starting at £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 variant with microLED display – nearly twice the price of the standard Fenix 8.

Users receive a lot of functionality for your investment, with best-in-class workout, activity and outdoor monitoring. The complete offline maps of the world can automatically direct you back to the path if you lose your way without a phone, and appear great on the large, sharp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. But the 47mm OLED model as reviewed does have an additional day of watch battery life even with the display on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan tied to your phone provider, like other smartwatches. But in contrast to Apple or Google's satellite-capable products, emergency communication is not included for free.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and audio messages, calls and LiveTrack location sharing – so your friends or loved ones can monitor you while out jogging, cycling or similar activities – plus emergency satellite SOS alerts.

Location updates and messages over satellite are then charged additionally, with more expensive plans offering different allowances of orbital usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

After you have completed setup, 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 tasks, but you can place and receive calls, send texts and generally stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then message reciprocally via text or spoken messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a phone number is enough to sign up for texts.

Texting on the watch works fine but composing texts on the small on-screen keyboard is slow. It includes a collection of personalizable pre-set responses you can send to expedite communication. Spoken messages and calls work acceptably, although as with the majority of smartwatches, you’re not going to wish to use it for extended discussions as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can configure to on its own transmit a URL to selected contacts whenever you start an exercise, so they can follow your live position on a map. It’s excellent for monitoring competition progress, but it primarily acts as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally worked effectively, although the real location has occasionally lagged when moving in and out of good LTE signal.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, location updates and SOS SOS.

A guide displays you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is important to remember that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available through the support site. The battery is certified to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin provides recycling schemes on recent 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 begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – along with satellite messaging, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable outdoor device for those that desire to be phone-free. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

This is quite freeing to be outside without a phone, but that capability carries a significant price, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to enable the service. At least it isn’t dependent on your phone provider so functions with all make of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when running, biking or trekking, but still desires to be trackable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and orbital communication, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Cons: extremely costly, LTE and orbital functions require ongoing payment, limited Garmin Pay bank compatibility, speech features are sluggish, basic smartwatch features compared with competing watches.
