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

The most recent version of the top-tier Fenix adventure watch includes a potentially lifesaving feature: no-phone communication and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new cellular technology, plus an available advanced microLED display in a limited edition. This is the brand's top device and designed to be the single tool required to venture virtually anywhere and track all your movements.

This positions it as an extremely expensive 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 variant with microLED screen – nearly double the price of the regular Fenix 8.

You do get a lot of functionality for your money, with best-in-class fitness, movement and adventure monitoring. Its full offline maps of the globe can seamlessly direct you back to the trail if you lose your way absent a phone, and appear excellent on the large, sharp and high-luminance touchscreen.

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

Phone-Free Texting, Calls and Live Tracking

The company operates its proprietary inReach LTE (4G) and satellite subscription service instead of relying on a watch plan linked to your phone carrier, as with other smartwatches. However unlike Apple or Google's satellite-enabled products, emergency communication is not provided for no cost.

Rather, plans begin from £7.99 or equivalent a month, which includes unlimited LTE text and audio messaging, call functionality and LiveTrack position tracking – so your friends or loved ones can keep an eye on you while out jogging, cycling or similar pursuits – plus emergency satellite SOS messaging.

Check-ins and texts via satellite are then billed additionally, with higher-tier subscriptions offering different allowances of orbital use, climbing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can test out the service.

Once you have got it set up, you simply head out outside minus your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you are able to place and receive calls, send texts and overall stay connected with your relatives and friends.

Whenever you text someone, Garmin dispatches them an SMS from a random number, which they can respond to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally via text or voice communications, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a mobile number is enough to sign up for texts.

Messaging on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It has a collection of personalizable pre-set responses you can send to expedite communication. Spoken messages and calls perform acceptably, though as with most wearables, you’re unlikely going to wish to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the handiest function. You can configure to on its own transmit a link to selected contacts whenever you begin an exercise, so they can track your live position on a map. It’s great for monitoring competition progress, but it primarily acts as a utility for someone you rely on to know your location in case an incident occurs. It has generally worked well, though the actual position has occasionally lagged when moving in and out of strong LTE coverage.

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

A on-screen assistance displays you how to find the clear view to the orbital system, 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 important to remember that orbital coverage is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding regions of Scandinavia above 65 degrees north.

Sustainability

The watch is generally repairable with options offered through the customer service site. The battery is certified to maintain at least 90% of its original power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling 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 optional Garmin inReach subscription plans 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 adds 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 even more impressive adventure tool for those that want to be phone-free. If you wish to have someone monitor you remotely while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is quite liberating to be outdoors without a phone, but that capability comes at a significant price, both in terms of the colossal price of the watch and the monthly subscription of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a killer gadget for someone who hates being burdened by their phone when jogging, biking or trekking, but nevertheless wants to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and satellite messaging, high-luminance OLED screen, tracks all activities with premier GPS, built-in torch, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touch.

Drawbacks: very costly, LTE and satellite functions need monthly subscription, restricted Garmin Pay financial support, speech features are sluggish, limited smartwatch features versus competing watches.
