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

This most recent iteration of Garmin's top-tier Fenix adventure watch introduces a life-saving feature: phone-free messaging and emergency alerts using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new mobile technology, along with an optional advanced microLED screen in a special edition. This is Garmin's top device and engineered to be the only tool needed to explore almost any location and monitor every activity.

This positions it as an very pricey option, 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 twice the cost of the regular Fenix 8.

Users get a significant features for your money, with best-in-class workout, movement and outdoor monitoring. Its full offline mapping of the world can automatically direct you back to the path if you get lost absent a phone, and look excellent on the sizable, crisp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the smaller 43mm version available in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed boasts an additional day of watch battery life even with the display always active, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan tied to your phone provider, like other smartwatches. However in contrast to competing satellite-enabled devices, SOS messaging is not provided for no cost.

Rather, plans begin from £7.99 or similar a month, which provides limitless LTE text and voice messaging, calls and LiveTrack location sharing – so your contacts or family can keep an eye on you while engaged in running, biking or similar activities – along with emergency orbital SOS alerts.

Check-ins and texts via satellite are then billed on top, with more expensive subscriptions including various quotas of satellite usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have got it set up, you just head out outside without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you can make and take calls, dispatch texts and generally keep in touch with your relatives and friends.

When you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally via text or spoken communications, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, just a mobile number is enough to register for texts.

Messaging on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It includes a collection of customisable pre-set responses you can send to speed things up. Spoken messages and calls work acceptably, although as with the majority of wearables, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to chosen contacts every time you start an activity, so they can follow your real time position on a map. It’s great for following competition progress, but it mostly serves as a tool for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned effectively, though the actual location has sometimes lagged when moving in and out of good LTE coverage.

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

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

Environmental Impact

The watch is typically serviceable with options available via the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks 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 subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re without signal.

Outcome is an increasingly remarkable outdoor device for those that desire to be unplugged. If you want to have someone monitor you from afar while exercising after dark or in the remote areas, the Garmin does so without needing additional gear.

This is quite liberating to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the colossal price of the watch and the monthly fee of the inReach service to enable the service. Fortunately it isn’t dependent on your phone carrier so functions with any make of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, tracks all activities with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely costly, LTE and orbital functions require ongoing subscription, restricted Garmin Pay financial support, speech capabilities are slow, basic wearable features versus competing watches.
