Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Messaging

The most recent iteration of the premium Fenix outdoor timepiece introduces a potentially lifesaving capability: no-phone communication and SOS alerts using 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new cellular technology, along with an available advanced microLED screen in a special edition. It is Garmin's premier model and engineered to be the single tool needed to explore almost anywhere and monitor all your movements.

This makes it an very pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost double the cost of the standard Fenix 8.

You do receive a lot of features for your investment, with best-in-class workout, movement and outdoor tracking. The full offline mapping of the globe can automatically direct you back to the path if you get lost without a phone, and look excellent on the large, crisp and super-bright display.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, omitting the more compact 43mm version found in other models, so it is a big watch for larger wrists. But the 47mm OLED model as reviewed boasts an additional day of watch battery life despite the screen on all the time, enduring a reliable eight to nine days between charging.

No-Phone Messaging, Calls and Live Tracking

The company operates its own inReach LTE (4G) and orbital subscription service rather than relying on a watch plan linked to your phone provider, as with other smartwatches. But in contrast to Apple or Google's satellite-capable products, emergency communication is not included for free.

Instead, subscriptions start at £7.99 or similar a month, which provides limitless LTE text and audio messaging, call functionality and LiveTrack position tracking – so your contacts or family can monitor you while engaged in running, biking or comparable pursuits – along with emergency orbital SOS messaging.

Check-ins and messages over satellite are then charged on top, with higher-tier plans including various quotas of orbital usage, increasing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can evaluate the functionality.

After you have completed setup, you just venture outside minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, 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 arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally using typed or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, only a mobile number is sufficient to sign up for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is slow. It has a collection of personalizable canned replies you can send to speed things up. Spoken recordings and calls perform OK, although as with the majority of wearables, you’re unlikely going to want to use it for extended discussions as the quality is less than fantastic.

LiveTrack is the handiest function. You can configure to on its own send a link to chosen contacts every time you begin an exercise, so they can follow your real time position on a map. It’s excellent for monitoring competition progress, but it primarily serves as a tool for someone you rely on to know your location in case an incident occurs. It has typically worked effectively, although the actual position has sometimes been delayed when moving 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 does not reach, the orbital kicks in on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial safety feature, however it is essential to remember that satellite coverage is restricted to the US mainland, most of Canada, and most of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with services offered via the support site. The battery is rated to maintain at least 90% of its initial power after two years of regular charging. The watch does not contain any reused components. Garmin provides recycling schemes on recent purchases.

Price

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – along with orbital communication, location update and emergency SOS for when you’re out of coverage.

Outcome is an increasingly remarkable adventure device for those that want to be phone-free. If you wish to have someone monitor you from afar while running after dark or in the remote areas, the Garmin accomplishes this without needing additional gear.

It is very liberating to be outdoors without a phone, but that capability carries a significant cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach plan to enable the service. At least it is not reliant on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but nevertheless desires to be locatable and contactable. For other users, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in torch, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touchscreen.

Drawbacks: very expensive, LTE and orbital features need ongoing subscription, limited Garmin Pay financial support, speech features are sluggish, basic smartwatch features versus competing watches.
