Garmin Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for Phone-Free Texting

This most recent iteration of the top-tier Fenix adventure watch introduces a life-saving capability: no-phone communication and SOS messaging via 4G LTE or satellite links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an available advanced microLED screen in a limited edition. It is Garmin's top model and designed to be the only gadget needed to venture almost any location and track all your movements.

That makes it an extremely expensive proposition, 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 screen – almost double the cost of the standard Fenix 8.

You do receive a significant features for your money, with industry-leading workout, activity and outdoor tracking. Its full offline mapping of the globe can automatically direct you back to the trail if you get lost without a phone, and look excellent on the large, sharp and super-bright display.

This Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the smaller 43mm version available in other devices, so it is a large watch for larger wrists. However the 47mm OLED version as reviewed does have an additional day of watch battery life despite the display always active, lasting a solid eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite service plan instead of depending on a watch plan linked to your mobile provider, as with other smartwatches. But in contrast to competing satellite-enabled devices, emergency messaging is not provided for free.

Rather, plans begin from £7.99 or similar a month, which provides limitless LTE SMS and audio messaging, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while out running, biking or similar pursuits – along with emergency satellite SOS messaging.

Check-ins and texts over orbital are then charged on top, with more expensive plans offering different quotas of satellite usage, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out the functionality.

After you have got it set up, you just head out the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you are able to make and take calls, send texts and generally keep in touch with your relatives and friends.

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 install the Garmin Messenger app, you can then communicate back and forth using typed or spoken communications, and make voice calls. Your recipient does not need a Garmin account to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable canned replies you can use to expedite communication. Spoken messages and calls work acceptably, although as with the majority of wearables, you’re not going to wish to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can configure to on its own transmit a link to selected contacts whenever you begin an activity, so they can follow your real time location on a map. It’s excellent for following competition progress, but it primarily acts as a utility for someone you trust to be aware of your whereabouts in case something happens. It has typically worked effectively, although the real position has sometimes been delayed when moving in and out of strong LTE coverage.

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

A guide shows you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a vital lifeline, though it is important to remember that orbital coverage is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with options available through the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin offers recycling programs on recent purchases.

Price

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

Conclusion

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 orbital communication, check-in and SOS SOS for when you’re out of coverage.

Outcome is an even more impressive outdoor tool for those that desire to be unplugged. If you want to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

It is quite liberating to be outdoors without a phone, but that functionality carries a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to provide the service. Fortunately it is not dependent on your phone provider so works with any make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, cycling or trekking, but still desires to be locatable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: extremely expensive, LTE and orbital functions need ongoing payment, limited Garmin Pay financial support, voice capabilities are sluggish, basic smartwatch functionality versus competing watches.
