Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

The newest model of Garmin's top-tier Fenix outdoor timepiece introduces a potentially lifesaving feature: phone-free messaging and SOS alerts using 4G LTE or satellite connections.

This Fenix 8 Pro enhances the previously outstanding Fenix 8 by incorporating new cellular technology, along with an optional advanced microLED screen in a special edition. It is Garmin's premier device and engineered to be the single tool required to explore almost any location and monitor all your movements.

That makes it an extremely pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the cost of the regular Fenix 8.

Users get a lot of features for your investment, with industry-leading workout, activity and adventure tracking. Its full offline mapping of the world can automatically direct you back to the trail if you lose your way without a phone, and appear excellent on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other devices, so it is a big watch for larger wrists. However the 47mm OLED version as tested does have an additional day of watch battery life even with the display on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and orbital subscription service instead of relying on a watch plan tied to your phone provider, like other smartwatches. However unlike competing satellite-enabled products, SOS messaging is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which provides limitless LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your contacts or family can keep an eye on you while engaged in jogging, cycling or comparable pursuits – plus SOS satellite SOS messaging.

Check-ins and messages over orbital are then billed additionally, with higher-tier plans offering different allowances of orbital use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can evaluate the service.

Once you have completed setup, you simply head out the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you can place and receive calls, send texts and overall stay connected with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then communicate back and forth via text or spoken messages, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to sign up for texts.

Texting on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable canned responses you can send to speed things up. Voice messages and calls work acceptably, though as with the majority of wearables, you’re not going to wish to use it for lengthy discussions as the quality is not fantastic.

LiveTrack is the most useful function. You can set it up to automatically transmit a URL to selected contacts every time you begin an activity, so they can track your live location on a map. It’s great for following race performance, but it mostly serves as a utility for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned effectively, although the real position has sometimes been delayed when transitioning in and out of good LTE signal.

These capabilities are accessible on other Garmin watches 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 SOS SOS.

A guide shows you how to find the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial safety feature, however it is essential to note that orbital coverage is restricted to the US mainland, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available via the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled materials. Garmin provides disposal schemes on new 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 plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a fantastic outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re without signal.

The result is an even more remarkable outdoor device 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 needing anything else.

It is quite freeing to be outside without a phone, but that functionality carries a significant cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to enable the features. At least it is not dependent on your phone carrier so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and satellite functions require ongoing subscription, limited Garmin Pay financial support, speech features are sluggish, limited wearable functionality versus competing watches.
