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

The most recent iteration of the premium Fenix adventure watch includes a life-saving feature: no-phone messaging and SOS messaging via 4G LTE or orbital links.

The Fenix 8 Pro enhances the already outstanding Fenix 8 by incorporating new mobile technology, plus an available advanced microLED screen in a special edition. It is Garmin's top device and designed to be the single gadget required to venture almost any location and track every activity.

That makes it an very expensive proposition, priced from £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 variant with microLED screen – almost double the cost of the standard Fenix 8.

Users get a significant functionality for your money, with best-in-class workout, movement and adventure tracking. Its full offline mapping of the globe can automatically direct you back to the trail if you lose your way absent a phone, and appear great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other models, so it is a big watch for bigger wrists. But the 47mm OLED model as reviewed does have an extra day of watch battery life despite the display on all the time, lasting a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Live Tracking

The company operates its proprietary inReach LTE (4G) and orbital service service rather than depending on a watch plan linked to your phone carrier, like other smartwatches. But unlike Apple or Google's satellite-enabled devices, emergency messaging is not included for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes limitless LTE text and voice messaging, call functionality and LiveTrack position sharing – so your friends or family can monitor you while engaged in jogging, cycling or similar activities – along with emergency orbital SOS messaging.

Check-ins and texts over satellite are then billed on top, with higher-tier plans including different quotas of satellite use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can test out the service.

Once you have completed setup, you simply head out the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you are able to make and take calls, send texts and generally keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally using typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger app, only a phone number is enough to register for texts.

Texting on the watch works fine but composing texts on the small on-screen keyboard is slow. It includes a set of personalizable pre-set responses you can use to expedite communication. Spoken messages and calls perform acceptably, although as with the majority of smartwatches, you’re not going to want to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the most useful function. You can configure to on its own send a URL to chosen contacts whenever you start an exercise, so they can track your real time position on a map. It’s excellent for monitoring race performance, but it primarily acts as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally functioned well, though the actual location has sometimes been delayed when transitioning in and out of strong LTE coverage.

These capabilities are accessible on other Garmin devices 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 transmit texts, location updates and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, however it is important to note that orbital coverage is restricted to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services available via 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 components. Garmin offers disposal schemes on recent 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 subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

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

Outcome is an even more remarkable outdoor device for those that desire to be phone-free. If you wish to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin does so without needing anything else.

This is quite freeing to be outside without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the monthly fee of the inReach service to provide the service. At least it is not dependent on your phone carrier so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, cycling or hiking, but nevertheless desires to be locatable and contactable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital messaging, high-luminance OLED screen, monitors everything with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: very costly, LTE and satellite features need ongoing payment, restricted Garmin Pay financial support, speech features are sluggish, limited wearable functionality versus Apple/Google/Samsung watches.
