Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Communication for Phone-Free Messaging

The most recent model of Garmin's top-tier Fenix outdoor timepiece includes a life-saving capability: phone-free messaging and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an available state-of-the-art microLED screen in a special edition. This is the brand's premier model and designed to be the single tool needed to venture virtually anywhere and track every activity.

This makes it an very pricey proposition, 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 edition with microLED screen – almost double the cost of the standard Fenix 8.

You do receive a lot of features for your money, with industry-leading workout, movement and adventure tracking. Its complete offline mapping of the world can automatically guide you return to the trail if you get lost without a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed does have an additional day of smartwatch battery life despite the display on all the time, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

Garmin uses its own inReach LTE (4G) and orbital subscription service instead of depending on a watch plan tied to your phone provider, like other smartwatches. However unlike Apple or Google's satellite-capable devices, SOS messaging is not included for free.

Rather, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, calls and LiveTrack position tracking – so your friends or loved ones can monitor you while out jogging, biking or similar activities – along with emergency satellite SOS messaging.

Check-ins and texts via orbital are then charged additionally, with higher-tier subscriptions offering various allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the service.

After you have got it set up, you just venture outside minus your phone and the watch will link to LTE. You can not use it for playing music or similar tasks, but you are able to make and take calls, dispatch texts and generally stay connected with your family and companions.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via 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 functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned replies you can send to speed things up. Spoken messages and calls work OK, although as with the majority of smartwatches, you’re not going to wish to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the most useful function. You can set it up to on its own transmit a link to selected contacts every time you begin an activity, so they can track your real time location on a map. It’s excellent for monitoring competition progress, but it primarily serves as a tool for someone you trust to know your location in case something happens. It has generally worked well, though the real location has sometimes been delayed when transitioning in and out of strong LTE signal.

All of these capabilities are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, location check-ins and SOS SOS.

A guide shows you how to find the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial lifeline, however it is essential to note that satellite service is limited 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 generally serviceable with services offered via the support portal. 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 reused materials. Garmin provides disposal programs on recent purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital communication, check-in and SOS SOS for when you’re without coverage.

The result is an even more remarkable adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you remotely while running out at night or in the remote areas, the Garmin does so without requiring additional gear.

It is quite liberating to be outdoors without a phone, but that capability carries a significant price, both in terms of the colossal price of the watch and the recurring fee of the inReach service to provide the service. At least it is not reliant on your phone provider so works with all make of smartphone and carrier.

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

Pros: LTE and orbital messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in torch, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Cons: extremely expensive, LTE and orbital functions require monthly subscription, restricted Garmin Pay bank support, voice capabilities are sluggish, limited smartwatch functionality versus Apple/Google/Samsung watches.
