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

The latest iteration of Garmin's flagship Fenix adventure timepiece includes a potentially lifesaving feature: no-phone messaging and SOS alerts via 4G LTE or orbital links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by adding cutting-edge cellular technology, along with an optional state-of-the-art microLED display in a special edition. It is the brand's premier device and designed to be the only gadget needed to explore almost anywhere and track every activity.

That makes it an extremely pricey option, 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 variant with microLED screen – almost twice the cost of the regular Fenix 8.

Users receive a significant functionality for your investment, with industry-leading workout, movement and outdoor monitoring. Its full offline maps of the globe can seamlessly direct you return to the path if you lose your way absent a phone, and appear excellent on the large, crisp and high-luminance display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, not the more compact 43mm size found in other devices, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed boasts an extra day of smartwatch battery life even with the display always active, enduring a reliable eight to nine days between charging.

Phone-Free Messaging, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital subscription plan instead of relying on a watch plan linked to your mobile carrier, like other wearables. But in contrast to competing satellite-enabled devices, SOS messaging is not provided for free.

Rather, subscriptions begin from £7.99 or similar a month, which includes limitless LTE text and audio messages, call functionality and LiveTrack location tracking – so your friends or loved ones can keep an eye on you while out jogging, cycling or comparable pursuits – along with SOS satellite SOS alerts.

Location updates and texts over orbital are then billed additionally, with more expensive plans offering various quotas of orbital use, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

After you have got it set up, you just head out the door without your phone and the watch will connect to LTE. You cannot use it for streaming music or comparable tasks, but you are able to make and take calls, send texts and overall keep in touch with your relatives and companions.

When you message 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 app, you can then message back and forth using text or voice communications, and make voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a mobile number is enough to register 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 customisable pre-set responses you can send to speed things up. Voice messages and calls perform OK, though as with the majority of wearables, you’re not going to wish to use it for lengthy discussions as the audio clarity is not ideal.

LiveTrack is the handiest feature. You can set it up to automatically transmit a link to selected contacts whenever you start an activity, so they can track your live location on a map. It’s great for following competition performance, but it mostly serves as a utility for someone you rely on to be aware of your location in case an incident occurs. It has generally worked well, though the actual position has occasionally been delayed when moving in and out of good LTE signal.

These capabilities are accessible on other Garmin watches if you carry your phone with you, but in areas 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 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 lifeline, however it is important to remember that orbital service is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options available through the customer service portal. The battery is rated to retain at least 90% of its original capacity after two years of regular charging. The watch does not contain any recycled components. Garmin offers disposal schemes on new purchases.

Cost

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 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 adds LTE for texting, call functionality and LiveTrack – along with satellite communication, location update and emergency SOS for when you’re without coverage.

Outcome is an increasingly impressive outdoor tool for those that want to be unplugged. If you wish to have someone monitor you from afar while running after dark or in the remote areas, the Garmin accomplishes this without needing anything else.

This is very liberating to be outside without a phone, but that functionality comes at quite a cost, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the features. At least it is not reliant on your phone carrier so works with any brand of smartphone and network.

The Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when jogging, biking or trekking, but still desires to be trackable and contactable. For other users, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, high-luminance OLED display, tracks all activities with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and satellite functions need ongoing payment, restricted Garmin Pay financial compatibility, voice features are slow, basic smartwatch features compared with competing watches.
