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

This latest model of Garmin's premium Fenix adventure watch introduces a life-saving feature: phone-free messaging and emergency alerts using 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding cutting-edge cellular tech, along with an available state-of-the-art microLED display in a limited edition. This is Garmin's top device and designed to be the only gadget required to venture virtually any location and track every activity.

This makes it an extremely 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 edition with microLED screen – almost twice the price of the standard Fenix 8.

Users receive a significant features for your money, with industry-leading workout, activity and adventure tracking. The full offline mapping of the globe can automatically guide you back to the trail if you get lost without a phone, and appear excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, not the more compact 43mm size found in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as reviewed boasts an additional day of watch battery life despite the display always active, enduring a solid eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan linked to your phone provider, as with other smartwatches. However unlike Apple or Google's satellite-capable devices, SOS communication is not provided for no cost.

Instead, subscriptions begin from £7.99 or equivalent a month, which includes limitless LTE SMS and voice messages, calls and LiveTrack location sharing – so your friends or loved ones can monitor you while engaged in running, biking or similar activities – along with SOS satellite SOS messaging.

Location updates and texts via satellite are then charged additionally, with higher-tier subscriptions offering different allowances of satellite use, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have completed setup, you just head out the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you are able to place and receive calls, dispatch texts and overall stay connected with your relatives and friends.

Whenever you text someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally via typed or voice messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger app, only a mobile number is enough to sign up for texts.

Texting on the watch works adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a set of personalizable canned replies you can use to expedite communication. Voice messages and calls perform acceptably, although as with the majority of wearables, you’re unlikely going to wish to use it for extended discussions as the quality is not fantastic.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to selected contacts whenever you start an activity, so they can track your live position on a map. It’s great for monitoring race progress, but it primarily acts as a tool for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally functioned well, though the real position has sometimes lagged when moving in and out of strong LTE coverage.

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

A on-screen assistance shows you how to locate the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, though it is important to note that satellite service is limited to the US continent, the majority of Canada, and the majority of Europe excluding regions of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with services offered through the support portal. The battery is rated to maintain at least 90% of its original capacity after two years of regular charging. The watch does not contain any reused components. Garmin provides disposal schemes on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach service packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus orbital messaging, location update and SOS SOS for when you’re without coverage.

Outcome is an increasingly remarkable adventure tool for those that want to be unplugged. If you want to have someone monitor you remotely while exercising out at night or in the middle of nowhere, the Garmin does so without requiring additional gear.

It is very liberating to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the substantial 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 works with any make of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, cycling or trekking, but still desires to be trackable and reachable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite communication, super-bright OLED display, monitors all activities with best-in-class GPS, integrated torch, voice and standalone voice control, 8+ day endurance, Garmin Pay, full offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: very costly, LTE and satellite features require monthly subscription, limited Garmin Pay financial compatibility, speech features are slow, limited wearable functionality versus competing watches.
