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

The most recent iteration of Garmin's flagship Fenix outdoor watch introduces a life-saving feature: phone-free messaging and SOS messaging using 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding cutting-edge mobile technology, plus an available advanced microLED display in a special edition. It is the brand's top device and engineered to be the single gadget required to venture almost any location and monitor 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 climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost twice the cost of the regular Fenix 8.

You do get a lot of functionality for your investment, with best-in-class workout, movement and adventure tracking. The complete offline maps of the globe can seamlessly guide you back to the trail if you get lost absent a phone, and appear great on the sizable, crisp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life despite the screen on all the time, lasting a solid eight to nine days between charging.

Phone-Free Texting, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription service rather than depending on a watch plan linked to your phone provider, like other wearables. However in contrast to competing satellite-enabled products, emergency messaging is not included 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 loved ones can monitor you while engaged in jogging, cycling or comparable pursuits – along with emergency orbital SOS alerts.

Location updates and messages via satellite are then billed additionally, with higher-tier subscriptions offering various allowances of orbital usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the functionality.

Once you have completed setup, you simply venture the door minus your phone and the watch will link to LTE. You can not use it for playing music or similar activities, but you can make and take calls, send texts and generally stay connected with your family and friends.

When you message someone, Garmin dispatches them an SMS from a random phone number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then message back and forth via typed or spoken communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, only a mobile number is sufficient to register for texts.

Texting on the watch functions fine but composing texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable pre-set responses you can send to speed things up. Voice messages and calls perform acceptably, though as with most smartwatches, 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 on its own send a URL to selected contacts every time you begin an activity, so they can track your live position on a map. It’s excellent for monitoring race progress, but it mostly acts as a utility for someone you rely on to know your location in case something happens. It has typically functioned well, though the actual location has sometimes lagged when transitioning in and out of good LTE coverage.

All of these capabilities are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A guide shows you how to locate the clear view to the orbital system, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, however it is important to note that orbital coverage is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options available through the support site. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch lacks any reused materials. Garmin offers recycling programs on recent purchases.

Price

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

Verdict

The 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 satellite messaging, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly impressive outdoor tool for those that desire to be unplugged. If you wish to have someone keep an eye on you from afar while running after dark or in the remote areas, the Garmin does so without needing additional gear.

It is quite liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach plan to provide the features. Fortunately it is not reliant on your phone provider so works with all make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, biking or hiking, but nevertheless desires to be trackable and contactable. For other users, it is a significant money when the excellent Fenix 8 is already available.
