The Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Texting

The latest iteration of the top-tier Fenix adventure timepiece includes a life-saving capability: phone-free communication and emergency alerts via 4G LTE or orbital connections.

The Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating cutting-edge cellular technology, along with an available state-of-the-art microLED screen in a special edition. It is Garmin's premier model and engineered to be the single gadget needed to venture virtually anywhere and track every activity.

This makes it an very pricey proposition, starting at £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 screen – nearly double the price of the standard Fenix 8.

You do receive a lot of features for your money, with best-in-class workout, movement and adventure monitoring. The full offline maps of the world can automatically direct you return to the trail if you get lost without a phone, and appear great on the large, crisp and super-bright display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm version available in other models, so it is a big watch for larger wrists. However the 47mm OLED version as tested does have an extra day of watch battery life despite the display always active, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

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. But in contrast to Apple or Google's satellite-capable devices, SOS communication is not included for no cost.

Rather, subscriptions start at £7.99 or similar a month, which includes unlimited LTE text and audio messages, calls and LiveTrack position sharing – so your friends or family can monitor you while engaged in jogging, cycling or comparable pursuits – plus emergency satellite SOS messaging.

Location updates and messages over orbital are then billed on top, with more expensive subscriptions including different allowances of orbital use, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the functionality.

Once you have got it set up, you simply venture the door minus your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you can make and take calls, send texts and generally keep in touch with your relatives and friends.

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

Messaging on the watch functions adequately but composing texts on the small on-screen keyboard is time-consuming. It has a set of customisable canned replies you can send to speed things up. Voice messages and calls work acceptably, although as with most smartwatches, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest function. You can set it up to automatically transmit a URL to selected contacts every time you begin an activity, so they can follow your real time location on a map. It’s excellent for monitoring race progress, but it primarily serves as a tool for someone you rely on to know your location in case an incident occurs. It has generally functioned effectively, although the actual location has occasionally lagged when transitioning in and out of good LTE coverage.

These capabilities are available on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position updates and emergency SOS.

A on-screen assistance displays you how to locate the line of sight to the satellite, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is important to remember that satellite coverage is limited to the US mainland, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally repairable with services available through the support portal. 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 recycling schemes on new purchases.

Cost

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

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus orbital messaging, location update and emergency SOS for when you’re out of coverage.

The result is an increasingly impressive adventure device for those that want to be phone-free. If you wish to have someone monitor you remotely while exercising after dark or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is very freeing to be outside without a phone, but that functionality carries a significant cost, both in terms of the colossal price of the watch and the recurring fee of the inReach service to enable the service. At least it is not dependent on your phone provider so works with all brand of smartphone and carrier.

The Fenix 8 Pro is a killer gadget for someone who dislikes being weighed down by their phone when jogging, biking or hiking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite communication, super-bright OLED display, tracks all activities with best-in-class GPS, integrated flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely expensive, LTE and orbital features require ongoing payment, limited Garmin Pay financial support, voice capabilities are slow, basic wearable functionality compared with Apple/Google/Samsung watches.
