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

The latest iteration of the premium Fenix outdoor watch introduces a potentially lifesaving capability: phone-free messaging and SOS alerts using 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by adding new mobile tech, along with an available advanced microLED display in a special edition. It is the brand's premier device and designed to be the only gadget needed to venture almost anywhere and track every activity.

That makes it an extremely pricey proposition, priced from £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 – almost twice the price of the standard Fenix 8.

Users receive a significant features for your money, with best-in-class fitness, movement and outdoor tracking. The full offline mapping of the globe can automatically direct you return to the path if you lose your way without a phone, and look great on the sizable, sharp and high-luminance display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite service plan rather than depending on a watch plan linked to your phone provider, like other wearables. But unlike Apple or Google's satellite-enabled products, SOS communication is not provided for free.

Rather, subscriptions start at £7.99 or equivalent a month, which includes limitless LTE SMS and voice messages, call functionality and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in jogging, cycling or comparable activities – plus emergency orbital SOS messaging.

Check-ins and texts via satellite are then billed additionally, with more expensive subscriptions including various allowances of orbital usage, increasing to a £50 a month unlimited subscription. The watch comes with a 30-day free trial so you can test out the functionality.

After you have completed setup, you simply venture the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you can make and take calls, send texts and generally stay connected with your family and friends.

When you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then communicate back and forth via typed or voice communications, and make voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is enough to register for texts.

Texting on the watch functions adequately but composing texts on the small on-screen keyboard is slow. It has a collection of personalizable pre-set responses you can send to expedite communication. Voice recordings and calls work acceptably, although as with most smartwatches, you’re not going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the handiest feature. You can set it up to on its own transmit a link to selected contacts whenever you start an activity, so they can follow your live position on a map. It’s great for monitoring competition progress, but it mostly serves as a utility for someone you trust to know your location in case an incident occurs. It has generally functioned well, although the actual location has sometimes lagged when moving in and out of good LTE signal.

These capabilities are available on other Garmin watches if you carry your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A on-screen assistance displays you how to find the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital safety feature, however it is important to remember that satellite coverage is restricted to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with options available via the customer service site. The battery is certified to retain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any recycled materials. Garmin offers recycling programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite communication, check-in and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable adventure tool for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

It is very liberating to be outdoors without a phone, but that functionality carries a significant price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to provide the service. Fortunately it isn’t dependent on your phone carrier so works with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, biking or trekking, but nevertheless wants to be trackable and contactable. For other users, it is a significant expense when the excellent Fenix 8 is already available.
