The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for Phone-Free Texting

This latest iteration of the top-tier Fenix outdoor timepiece includes a life-saving feature: no-phone messaging and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile tech, along with an available advanced microLED display in a limited edition. This is Garmin's top device and designed to be the single tool required to venture virtually any location and track every activity.

That positions it as an very pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the cost of the standard Fenix 8.

Users receive a lot of features for your money, with best-in-class workout, activity and outdoor monitoring. Its full offline mapping of the globe can seamlessly direct you return to the trail if you get lost without a phone, and appear great on the sizable, crisp and high-luminance display.

This 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 large watch for larger wrists. However the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life even with the screen always active, enduring a solid eight to nine days between charges.

No-Phone Messaging, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and orbital service plan instead of depending on a watch plan tied to your phone provider, as with other smartwatches. However unlike competing satellite-capable products, SOS messaging is not included for free.

Instead, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messaging, calls and LiveTrack location tracking – so your friends or loved ones can monitor you while out jogging, biking or similar activities – along with SOS satellite SOS messaging.

Location updates and texts via satellite are then billed additionally, with higher-tier subscriptions offering various allowances of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can evaluate the service.

Once you have completed setup, you simply venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable activities, but you can make and take calls, dispatch texts and generally stay connected with your family and friends.

When you message someone, Garmin sends them an SMS from a arbitrary 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 sufficient to register for texts.

Texting on the watch works fine but typing out texts on the small on-screen keyboard is slow. It has a collection of personalizable pre-set responses you can use to speed things up. Voice recordings and calls perform acceptably, though as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest feature. You can configure to automatically send a URL to selected contacts whenever you begin an activity, so they can follow your live position on a map. It’s excellent for following competition performance, but it mostly serves as a tool for someone you rely on to be aware of your whereabouts in case an incident occurs. It has typically functioned well, though the actual location has sometimes been delayed when transitioning in and out of strong LTE coverage.

All of these capabilities are accessible on other Garmin devices if you carry 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 emergency 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 unexpectedly straightforward to use and could be a vital safety feature, though it is essential to note that orbital coverage is limited to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically serviceable with services offered through the support site. The battery is certified to retain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin offers disposal schemes on recent purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service packages begin 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 adds LTE for texting, call functionality and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re out of signal.

Outcome is an even more impressive outdoor tool for those that desire to be phone-free. If you want to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite freeing to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, cycling or hiking, but nevertheless desires to be trackable and reachable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, high-luminance OLED screen, tracks everything with premier GPS, built-in flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely expensive, LTE and orbital functions need monthly subscription, restricted Garmin Pay financial compatibility, speech capabilities are slow, limited wearable functionality versus competing watches.
