The Fenix 8 Pro Review: Integrated LTE and Satellite Communication for No-Phone Messaging

This latest model of the top-tier Fenix outdoor timepiece introduces a potentially lifesaving capability: phone-free messaging and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new cellular technology, plus an optional advanced microLED screen in a limited edition. This is the brand's premier model and designed to be the only tool needed to venture virtually anywhere and monitor every activity.

That makes it an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the cost of the regular Fenix 8.

You do receive a lot of functionality for your money, with best-in-class workout, movement and adventure monitoring. The complete offline mapping of the world can seamlessly guide you return to the trail 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 sizes, omitting the smaller 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as reviewed does have an additional day of smartwatch battery life even with the display always active, enduring a solid eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite service plan rather than depending on a watch plan tied to your phone provider, like other wearables. But unlike Apple or Google's satellite-enabled devices, SOS communication is not included for no cost.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE text and audio messages, call functionality and LiveTrack location tracking – so your contacts or loved ones can monitor you while engaged in running, cycling or similar activities – plus SOS satellite SOS messaging.

Check-ins and messages via satellite are then charged additionally, with more expensive subscriptions offering various allowances of satellite usage, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you simply venture outside minus your phone and the watch will link to LTE. You cannot use it for playing music or similar activities, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and companions.

When you message someone, Garmin sends them an SMS from a random phone number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally via typed or voice messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger app, just a mobile number is enough to sign up for texts.

Texting on the watch works adequately but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of personalizable pre-set replies you can send to expedite communication. Voice messages and calls work acceptably, although as with the majority of wearables, you’re unlikely going to wish to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the handiest feature. You can configure to automatically transmit a link to chosen contacts every time you begin an activity, so they can track your real time location on a map. It’s great for monitoring competition progress, but it primarily acts as a tool for someone you trust to know your location in case an incident occurs. It has typically worked effectively, although the actual location has sometimes lagged when transitioning in and out of good LTE coverage.

All of these features are available on other Garmin devices if you bring your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to send texts, location updates and SOS SOS.

A guide shows you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, however it is essential to note that satellite coverage is limited to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with services available through the support site. The battery is rated to retain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin offers recycling programs on recent purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re out of coverage.

Outcome is an increasingly impressive outdoor tool for those that want to be phone-free. If you wish to have someone monitor you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is very freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach service to enable the service. At least it is not dependent on your phone provider so functions with all make of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, biking or trekking, but still desires to be locatable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with premier GPS, integrated torch, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and orbital features require ongoing subscription, restricted Garmin Pay bank support, voice features are slow, limited wearable features versus competing watches.
