The Fenix 8 Pro Review: Built-in LTE and Orbital Communication for No-Phone Messaging

This latest model of Garmin's flagship Fenix outdoor timepiece introduces a potentially lifesaving feature: no-phone messaging and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by adding cutting-edge cellular tech, plus an optional state-of-the-art microLED display in a special edition. It is the brand's top model and designed to be the only tool required to explore virtually anywhere and track every activity.

This makes it an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the regular Fenix 8.

You do receive a lot of features for your investment, with industry-leading workout, activity and adventure monitoring. Its complete offline maps of the world can seamlessly direct you return to the trail if you get lost absent a phone, and look great on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other devices, so it is a large watch for larger wrists. But the 47mm OLED version as reviewed does have an additional day of smartwatch battery life even with the screen always active, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and satellite service plan instead of depending on a watch plan tied to your phone carrier, like other smartwatches. However in contrast to Apple or Google's satellite-capable products, emergency communication is not included for free.

Rather, subscriptions start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, call functionality and LiveTrack location tracking – so your contacts or family can monitor you while engaged in running, cycling or comparable activities – along with SOS satellite SOS messaging.

Location updates and texts via satellite are then billed on top, with more expensive subscriptions including various quotas of satellite usage, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the service.

After you have completed setup, you just head out outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, dispatch texts and generally keep in touch with your relatives and companions.

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

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It includes a collection of personalizable canned responses you can use to speed things up. Spoken recordings and calls perform OK, though as with the majority of smartwatches, you’re not going to want to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can configure to on its own transmit a URL to chosen contacts every time you begin an activity, so they can track your real time position on a map. It’s excellent for monitoring competition progress, but it primarily serves as a tool for someone you trust to know your whereabouts in case an incident occurs. It has generally functioned well, although the actual position has occasionally been delayed when transitioning in and out of strong LTE signal.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance displays you how to find the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is essential to remember that orbital coverage is limited to the US mainland, the majority of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically repairable with services available via the customer service site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled components. Garmin offers disposal programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re without coverage.

Outcome is an increasingly impressive outdoor device for those that want to be unplugged. If you wish 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 requiring anything else.

It is quite liberating to be outdoors without a phone, but that capability carries quite a cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to provide the service. Fortunately it is not reliant on your phone carrier so works with all brand of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, cycling or hiking, but still desires to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite communication, high-luminance OLED display, tracks all activities with best-in-class GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: extremely costly, LTE and satellite features require ongoing payment, limited Garmin Pay bank support, speech features are sluggish, limited smartwatch features versus Apple/Google/Samsung watches.
