The Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Messaging

This most recent model of the flagship Fenix outdoor timepiece introduces a potentially lifesaving feature: phone-free communication and emergency messaging using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new cellular technology, plus an available advanced microLED display in a special edition. It is Garmin's top model and engineered to be the only gadget needed to venture virtually any location and monitor every activity.

That makes it an extremely pricey proposition, starting at £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 edition with microLED screen – almost double the price of the regular Fenix 8.

You do receive a significant functionality for your money, with best-in-class fitness, activity and outdoor tracking. Its full offline maps of the globe can automatically direct you return to the trail if you lose your way absent a phone, and appear great on the large, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, not the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED version as tested boasts an additional day of watch battery life even with the display on all the time, enduring a reliable eight to nine days between charges.

No-Phone Texting, Calls and Live Tracking

The company uses its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan tied to your mobile carrier, like other wearables. However in contrast to Apple or Google's satellite-enabled devices, SOS communication is not included for no cost.

Instead, subscriptions start at £7.99 or similar a month, which provides limitless LTE SMS and audio messages, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while engaged in running, cycling or similar activities – plus emergency satellite SOS alerts.

Check-ins and texts over orbital are then billed on top, with more expensive subscriptions offering different allowances of satellite use, increasing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

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 can place and receive calls, dispatch texts and overall stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a random number, which they can respond to directly to your watch. If they install the Garmin Messenger application, you can then message back and forth using typed or voice messages, and initiate voice calls. Your contact does not need a Garmin account to use the Messenger application, just a phone number is enough to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It includes a set of personalizable pre-set replies you can use to expedite communication. Spoken messages and calls perform acceptably, though as with the majority of wearables, you’re not going to want to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the handiest feature. You can configure to on its own transmit a URL to chosen contacts whenever you begin an activity, so they can follow your live location on a map. It’s great for monitoring competition progress, but it primarily acts as a tool for someone you trust to know your whereabouts in case something happens. It has generally functioned effectively, though the actual location has sometimes been delayed when moving in and out of strong LTE signal.

These features are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide displays you how to locate the clear view to the satellite, which then sends and receives communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is essential to remember that satellite service is restricted to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with services available via the support site. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers disposal programs on new purchases.

Price

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

Verdict

The Fenix 8 Pro builds on a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital communication, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you wish to have someone keep an eye on you remotely while running after dark or in the remote areas, the Garmin accomplishes this without needing anything else.

It is very freeing to be outside without a phone, but that capability carries a significant cost, both in terms of the colossal cost of the watch and the recurring fee of the inReach plan to provide the features. At least it is not reliant on your phone carrier so functions with any brand of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when running, cycling or hiking, but nevertheless desires to be trackable and contactable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, tracks everything with premier GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: extremely costly, LTE and orbital functions need ongoing payment, restricted Garmin Pay financial compatibility, speech features are slow, basic wearable features versus competing watches.
