Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Communication for No-Phone Texting

The latest version of the premium Fenix outdoor watch brings a life-saving capability: phone-free messaging and SOS messaging using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the previously impressive Fenix 8 by adding cutting-edge cellular technology, plus an optional state-of-the-art microLED display in a special edition. It is the brand's top device and designed to be the only tool needed to venture almost any location and track all your movements.

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, activity and adventure tracking. The complete offline maps of the world can automatically guide you back to the trail if you lose your way absent a phone, and appear excellent on the sizable, sharp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as tested does have an additional day of watch battery life despite the display on all the time, lasting a solid eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital subscription service rather than depending on a watch plan tied to your mobile carrier, as with other wearables. However in contrast to Apple or Google's satellite-enabled products, SOS communication is not provided for free.

Rather, subscriptions start at £7.99 or similar a month, which includes limitless LTE text and voice messages, calls and LiveTrack location sharing – so your contacts or loved ones can keep an eye on you while out jogging, cycling or similar pursuits – plus emergency satellite SOS messaging.

Location updates and messages via satellite are then billed on top, with more expensive plans including various quotas of orbital use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day free trial so you can test out the functionality.

After you have got it set up, you simply head out the door without your phone and the watch will connect to LTE. You can not use it for streaming music or comparable tasks, but you can place and receive calls, send texts and overall keep in touch with your relatives and companions.

Whenever you message someone, Garmin dispatches them an SMS from a arbitrary number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then communicate reciprocally using text or voice communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It has a set of customisable pre-set responses you can use to speed things up. Voice messages and calls work acceptably, though as with the majority of wearables, you’re not going to want to use it for lengthy discussions as the quality is less than ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a URL to chosen contacts every time you start an exercise, so they can track your real time position on a map. It’s excellent for monitoring competition performance, but it mostly acts as a utility for someone you trust to be aware of your whereabouts in case an incident occurs. It has generally worked effectively, although the actual location has sometimes been delayed when transitioning in and out of good LTE signal.

These capabilities are available on other Garmin devices if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, location updates and emergency SOS.

A guide displays you how to find the clear view to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is important to remember that orbital coverage is limited to the US continent, the majority of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with options available via the customer service site. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any recycled materials. Garmin provides disposal programs on recent purchases.

Price

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

Verdict

The Fenix 8 Pro takes a excellent outdoor watch in the regular Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive adventure tool for those that want to be phone-free. If you want to have someone keep an eye on you from afar while exercising after dark or in the middle of nowhere, the Garmin does so without needing anything else.

It is quite freeing to be outside without a phone, but that functionality carries quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach service to provide the service. Fortunately it isn’t reliant on your phone carrier so functions with all brand of smartphone and carrier.

This Fenix 8 Pro is a top-tier device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but still wants to be locatable and contactable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Pros: LTE and orbital messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely costly, LTE and satellite functions need monthly payment, restricted Garmin Pay financial support, speech capabilities are sluggish, limited smartwatch functionality compared with Apple/Google/Samsung watches.
