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

This latest iteration of the premium Fenix adventure watch introduces a potentially lifesaving capability: phone-free communication and emergency messaging via 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating cutting-edge mobile tech, plus an available state-of-the-art microLED screen in a special edition. It is the brand's premier device and designed to be the single tool required to venture almost any location and track every activity.

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

Users get a significant functionality for your investment, with industry-leading fitness, activity and adventure monitoring. The complete offline maps of the world can automatically guide you return to the trail if you get lost without a phone, and look excellent on the sizable, sharp and super-bright display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the more compact 43mm version found in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as tested boasts an additional day of watch battery life even with the screen on all the time, lasting a solid eight to nine days between charges.

Phone-Free Messaging, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite subscription service instead of depending on a watch plan tied to your phone provider, as with other smartwatches. But in contrast to Apple or Google's satellite-enabled products, SOS messaging is not provided for no cost.

Rather, plans begin from £7.99 or equivalent a month, which provides unlimited LTE text and voice messaging, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while out jogging, cycling or comparable pursuits – plus SOS satellite SOS alerts.

Check-ins and messages over satellite are then billed additionally, with higher-tier subscriptions including different quotas of satellite use, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you just head out outside minus your phone and the watch will link to LTE. You can not use it for streaming music or comparable activities, but you are able to place and receive calls, dispatch texts and overall stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then message back and forth via typed or voice communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, just a phone number is sufficient to sign up for texts.

Texting on the watch functions fine but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable canned responses you can use to expedite communication. Voice messages and calls work acceptably, although as with the majority of wearables, you’re not going to want to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the most useful function. You can set it up to on its own transmit a URL to selected contacts every time you start an exercise, so they can follow your real time location on a map. It’s excellent for monitoring competition progress, but it mostly acts as a tool for someone you trust to know your whereabouts in case something happens. It has typically worked well, though the actual position has occasionally been delayed when transitioning in and out of good LTE signal.

These capabilities are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to note that orbital coverage is limited to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically serviceable with options available via the customer service site. The battery is certified to retain at least 90% of its original power after two years of weekly charging. The watch lacks any reused components. Garmin offers recycling 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 service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

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

The result is an even more remarkable outdoor tool for those that want to be unplugged. If you wish to have someone monitor you from afar while running after dark or in the middle of nowhere, the Garmin accomplishes this 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 price of the watch and the recurring fee of the inReach plan to provide the service. At least it is not reliant on your phone carrier so works with all brand of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when running, biking or hiking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in torch, phone and offline commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely costly, LTE and orbital features need monthly subscription, restricted Garmin Pay bank compatibility, speech capabilities are sluggish, limited smartwatch features compared with competing watches.
