Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Texting

The most recent iteration of Garmin's flagship Fenix outdoor timepiece brings a potentially lifesaving capability: phone-free messaging and SOS messaging via 4G LTE or satellite links.

The Fenix 8 Pro enhances the previously impressive Fenix 8 by incorporating cutting-edge mobile technology, plus an optional advanced microLED screen in a special edition. This is Garmin's top model and designed to be the only tool required to venture virtually any location and monitor all your movements.

That makes it an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the cost of the standard Fenix 8.

You do receive a lot of features for your money, with industry-leading fitness, movement and adventure monitoring. The full offline maps of the world can seamlessly direct you back to the path if you lose your way absent a phone, and appear excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only available 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. However the 47mm OLED model as reviewed does have an extra day of watch battery life even with the screen on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite subscription plan rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. However unlike Apple or Google's satellite-capable devices, emergency communication is not included for no cost.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and audio messaging, calls and LiveTrack location tracking – so your friends or loved ones can monitor you while out jogging, biking or comparable activities – along with emergency orbital SOS alerts.

Location updates and messages via orbital are then charged on top, with more expensive subscriptions including various allowances of satellite use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out the service.

Once you have completed setup, you simply head out outside without your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you are able to place and receive calls, send texts and overall keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth using text or spoken communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a collection of personalizable pre-set responses you can send to expedite communication. Spoken recordings and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the most useful function. You can set it up to automatically transmit a link to chosen contacts every time you begin an activity, so they can track your live location on a map. It’s excellent for following competition progress, but it mostly serves as a tool for someone you trust to know your location in case an incident occurs. It has generally functioned well, though the real position has occasionally lagged when moving in and out of strong LTE signal.

These features are available on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is essential to remember that orbital coverage is restricted to the US mainland, most of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with services offered via the customer service site. 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 reused materials. Garmin provides disposal programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a fantastic outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital communication, location update and SOS SOS for when you’re without signal.

The result is an increasingly impressive adventure device for those that want to be phone-free. If you want to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin does so without needing additional gear.

This is very liberating to be outdoors without a phone, but that capability carries a significant cost, both in terms of the colossal cost of the watch and the monthly subscription of the inReach plan to enable the service. Fortunately it isn’t reliant on your phone carrier so functions with all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or trekking, but still desires to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, high-luminance OLED screen, monitors all activities with premier GPS, built-in torch, phone and standalone voice control, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very expensive, LTE and orbital features need ongoing subscription, limited Garmin Pay bank support, speech features are sluggish, limited wearable features versus Apple/Google/Samsung watches.
