Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Texting

This latest version of the flagship Fenix outdoor timepiece includes a life-saving capability: phone-free messaging and SOS alerts via 4G LTE or orbital connections.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an available advanced microLED display in a limited edition. This is Garmin's premier device and designed to be the single tool needed to venture virtually anywhere and track every activity.

This makes it an very expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost double the cost of the regular Fenix 8.

You do get a significant functionality for your money, with industry-leading workout, activity and outdoor tracking. The full offline maps of the world can automatically direct you back to the trail if you lose your way without a phone, and look great on the sizable, sharp and super-bright touchscreen.

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

No-Phone Messaging, Calling and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite subscription service rather than depending on a watch plan tied to your mobile provider, as with other wearables. However unlike Apple or Google's satellite-capable products, SOS messaging is not provided for no cost.

Instead, plans begin from £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, calls and LiveTrack location sharing – so your friends or family can monitor you while engaged in running, biking or similar activities – along with SOS orbital SOS messaging.

Location updates and messages over orbital are then charged on top, with more expensive subscriptions offering different quotas of satellite usage, increasing to a £50 a month unlimited 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 outside minus your phone and the watch will connect to LTE. You cannot use it for playing music or similar activities, but you can place and receive calls, send texts and overall stay connected with your relatives and companions.

When you text someone, Garmin dispatches them an SMS from a arbitrary number, which they can reply to back to your watch. If they install the Garmin Messenger application, you can then message reciprocally using text or spoken communications, and make voice calls. Your contact does not need a Garmin profile to use the Messenger app, just a phone number is enough to register for texts.

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It has a set of personalizable canned responses you can send to speed things up. Spoken messages and calls work acceptably, though as with the majority of smartwatches, you’re not going to wish to use it for lengthy conversations as the audio clarity is less than ideal.

LiveTrack is the most useful feature. You can configure to automatically send a URL to chosen contacts whenever you begin an exercise, so they can track your live position on a map. It’s great for following competition progress, but it primarily serves as a tool for someone you rely on to be aware of your location in case an incident occurs. It has generally functioned effectively, although the actual position has sometimes lagged when moving in and out of good LTE coverage.

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

A on-screen assistance displays you how to locate the line of sight to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial safety feature, however it is essential to note that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically repairable with services available via the support portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch lacks any recycled materials. Garmin provides disposal programs on recent purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without coverage.

Outcome is an increasingly impressive outdoor tool for those that desire to be phone-free. If you want to have someone keep an eye on you remotely while exercising out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

It is very freeing to be outside without a phone, but that capability comes at quite a price, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to provide the features. Fortunately it isn’t dependent on your phone provider so functions with any brand of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, cycling or hiking, but still desires to be locatable and reachable. For other users, it is a lot of money when the excellent Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, monitors all activities with best-in-class GPS, integrated flashlight, phone and standalone commands, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Drawbacks: extremely costly, LTE and satellite features need monthly payment, restricted Garmin Pay bank support, speech capabilities are sluggish, basic wearable functionality compared with competing watches.
