Garmin Fenix 8 Pro Analysis: Built-in LTE and Satellite Connectivity for No-Phone Texting

This latest version of Garmin's premium Fenix adventure timepiece brings a life-saving capability: phone-free communication and SOS alerts using 4G LTE or satellite links.

The Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding new mobile technology, plus an optional state-of-the-art microLED display in a special edition. This is the brand's premier model and designed to be the single tool needed to venture virtually any location and monitor all your movements.

This positions it as an extremely expensive proposition, priced from £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 edition with microLED display – almost twice the cost of the regular Fenix 8.

You do get a significant functionality for your investment, with industry-leading workout, activity and adventure monitoring. The complete offline mapping of the world can automatically direct you return to the path if you get lost absent a phone, and appear great on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the more compact 43mm version found in other devices, so it is a big watch for larger 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 reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite subscription service rather than depending on a watch plan linked to your mobile carrier, like other smartwatches. However in contrast to competing satellite-enabled products, SOS messaging is not provided for free.

Instead, subscriptions start at £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack position tracking – so your friends or loved ones can monitor you while engaged in running, cycling or similar activities – plus SOS orbital SOS alerts.

Check-ins and texts over satellite are then charged on top, with higher-tier plans including different allowances of satellite use, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the service.

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

Whenever you message someone, Garmin sends them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth via text or voice communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger application, just a mobile number is enough 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 collection of personalizable pre-set responses you can use to expedite communication. Voice messages and calls perform OK, although as with the majority of wearables, you’re unlikely going to wish to use it for lengthy discussions as the audio clarity is less than fantastic.

LiveTrack is the most useful function. You can set it up to on its own send a URL to chosen contacts whenever you start an exercise, so they can track your live location on a map. It’s excellent for following race progress, but it primarily acts as a utility for someone you trust to be aware of your whereabouts in case something happens. It has generally functioned well, although the real location has sometimes been delayed when transitioning in and out of good LTE signal.

All of these capabilities are available on other Garmin devices if you bring your phone with you, but in locations where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A guide displays you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, however it is important to note that satellite coverage is restricted to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Sustainability

The watch is typically repairable with options offered via the customer service site. The battery is rated to retain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled components. Garmin provides disposal schemes on recent purchases.

Price

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with satellite communication, check-in and SOS SOS for when you’re out of coverage.

Outcome is an increasingly remarkable adventure device for those that desire to be unplugged. If you want to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is quite liberating to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to provide the features. Fortunately it is not dependent on your phone provider so functions with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when running, cycling or hiking, but still desires to be trackable and contactable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors everything with premier GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touchscreen.

Drawbacks: very expensive, LTE and satellite features require ongoing subscription, restricted Garmin Pay bank compatibility, voice capabilities are sluggish, basic smartwatch features versus Apple/Google/Samsung watches.
