The Fenix 8 Pro Analysis: Built-in LTE and Satellite Communication for No-Phone Messaging

This latest model of Garmin's top-tier Fenix outdoor watch brings a potentially lifesaving capability: phone-free messaging and SOS messaging via 4G LTE or satellite connections.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, along with an optional advanced microLED display in a limited edition. It is Garmin's top model and designed to be the only gadget required to explore virtually any location and track every activity.

This positions it as an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly twice the price of the standard Fenix 8.

You do receive a significant functionality for your investment, with industry-leading workout, movement and adventure tracking. The complete offline maps of the globe can automatically direct you back to the trail if you get lost without a phone, and appear great on the large, sharp and super-bright display.

This Fenix 8 Pro is only 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 version as tested does have an additional day of smartwatch battery life even with the display always active, lasting a reliable eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan linked to your mobile provider, like other smartwatches. But in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not included for no cost.

Rather, plans start at £7.99 or similar a month, which includes unlimited LTE SMS and audio messages, call functionality and LiveTrack position tracking – so your friends or loved ones can monitor you while engaged in jogging, cycling or comparable activities – plus SOS satellite SOS alerts.

Location updates and messages over satellite are then billed on top, with higher-tier plans offering different allowances of satellite usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the functionality.

After you have got it set up, you simply head out the door without your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you can make and take calls, send texts and overall stay connected with your family and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally via typed or spoken communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, only a mobile number is enough to sign up for texts.

Texting on the watch works adequately but composing texts on the small on-screen keyboard is slow. It has a set of personalizable canned responses you can use to expedite communication. Voice recordings and calls perform OK, though as with most wearables, you’re not going to wish to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to selected contacts whenever you start an activity, so they can track your real time location on a map. It’s great for following competition progress, but it primarily serves as a utility for someone you rely on to know your location in case something happens. It has generally functioned effectively, although the real location has occasionally been delayed when transitioning in and out of good LTE coverage.

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

A guide shows you how to find the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, though it is essential to note that satellite service is limited to the US continent, the majority of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with services offered 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 recycled components. Garmin offers recycling programs on recent purchases.

Cost

This Fenix 8 Pro is priced 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

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, location update and SOS SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor device for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is quite freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach plan to enable the features. At least it isn’t dependent on your phone carrier so works with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when jogging, biking or hiking, but still desires to be trackable and contactable. For everyone else, it is a lot of money when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED display, tracks everything with premier GPS, integrated torch, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very expensive, LTE and orbital functions need ongoing subscription, restricted Garmin Pay financial compatibility, speech features are sluggish, basic smartwatch functionality versus Apple/Google/Samsung watches.
