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

The latest iteration of the flagship Fenix adventure timepiece introduces a potentially lifesaving capability: phone-free communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new mobile technology, along with an optional advanced microLED display in a limited edition. It is Garmin's premier device and designed to be the single gadget required to explore almost anywhere and track 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 colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – nearly double the cost of the standard Fenix 8.

Users get a lot of features for your money, with industry-leading workout, movement and adventure monitoring. Its complete offline maps of the globe can seamlessly direct you return to the path if you get lost absent a phone, and appear great on the sizable, sharp and high-luminance display.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed does have an extra day of watch battery life even with the display on all the time, lasting a reliable eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its own inReach LTE (4G) and satellite subscription service rather than relying on a watch plan tied to your mobile carrier, like other smartwatches. But unlike Apple or Google's satellite-capable products, SOS messaging is not provided for no cost.

Instead, subscriptions start at £7.99 or equivalent a month, which provides unlimited LTE SMS and audio messages, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while engaged in jogging, cycling or comparable activities – along with emergency orbital SOS alerts.

Check-ins and texts over satellite are then charged additionally, with higher-tier subscriptions offering various quotas of satellite usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the functionality.

Once you have completed setup, you simply head out the door without your phone and the watch will connect to LTE. You can not use it for playing music or comparable activities, but you are able to place and receive calls, dispatch texts and generally keep in touch with your family and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then communicate back and forth via text or voice communications, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, only a phone number is sufficient to sign up for texts.

Messaging on the watch works adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a collection of customisable canned replies you can send to expedite communication. Spoken recordings and calls work acceptably, though as with most wearables, you’re unlikely going to wish to use it for lengthy conversations as the quality is not fantastic.

LiveTrack is the most useful function. You can set it up to automatically transmit a link to chosen contacts every time you begin an exercise, so they can follow your live position on a map. It’s excellent for monitoring race performance, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case an incident occurs. It has generally worked well, though the actual position has occasionally been delayed when moving in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin devices 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, location updates and emergency SOS.

A on-screen assistance displays you how to locate 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 safety feature, however it is essential to remember that orbital coverage is restricted to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with options available via the customer service portal. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled components. Garmin provides disposal schemes on new purchases.

Price

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

Verdict

This Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, check-in and emergency SOS for when you’re without signal.

Outcome is an even more remarkable outdoor tool for those that desire to be phone-free. If you want to have someone monitor you from afar while running out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

This is very liberating to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to provide the features. Fortunately it is not dependent on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when jogging, biking or trekking, but still wants to be locatable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED display, monitors everything with premier GPS, integrated flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touch.

Cons: extremely expensive, LTE and orbital features need ongoing payment, limited Garmin Pay financial support, voice capabilities are slow, basic wearable features compared with competing watches.
