Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for Phone-Free Messaging

The latest version of Garmin's top-tier Fenix outdoor timepiece introduces a life-saving feature: phone-free messaging and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new mobile technology, along with an optional advanced microLED display in a special edition. It is the brand's top model and engineered to be the single tool required to venture virtually anywhere and monitor all your movements.

This positions it as an very expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the cost of the regular Fenix 8.

Users get a lot of features for your money, with best-in-class fitness, activity and outdoor monitoring. The complete offline mapping of the globe can automatically direct you return to the path if you get lost absent a phone, and appear excellent on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the smaller 43mm size found in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as tested does have an extra day of smartwatch battery life even with the screen on all the time, lasting a reliable eight to nine days between charging.

No-Phone Texting, Calls and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and satellite service plan instead of depending on a watch plan linked to your phone provider, as with other wearables. However in contrast to Apple or Google's satellite-enabled devices, SOS messaging is not included for no cost.

Instead, plans begin from £7.99 or equivalent a month, which provides unlimited LTE SMS and voice messaging, call functionality and LiveTrack location tracking – so your contacts or loved ones can monitor you while out running, biking or comparable activities – along with emergency satellite SOS messaging.

Check-ins and messages via orbital are then billed additionally, with higher-tier plans including different allowances of satellite use, increasing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the functionality.

After you have got it set up, you just head out the door minus your phone and the watch will link to LTE. You cannot use it for playing music or similar tasks, but you can make and take calls, dispatch texts and overall keep in touch with your family and friends.

When you message 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 spoken communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a phone number is enough to register for texts.

Messaging on the watch works adequately but composing texts on the tiny on-screen keyboard is slow. It includes a collection of customisable canned replies you can use to expedite communication. Spoken recordings and calls perform OK, though as with most wearables, you’re not going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful feature. You can configure to on its own transmit a URL to selected contacts whenever you begin an activity, so they can track your live position on a map. It’s great for monitoring race progress, but it mostly acts as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has typically worked well, though the actual location has sometimes lagged when transitioning in and out of strong LTE coverage.

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

A guide 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 unexpectedly straightforward to use and could be a vital lifeline, however it is essential to note that orbital service is limited to the US mainland, most of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically repairable with services available through the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch lacks any recycled components. Garmin offers disposal schemes on recent 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 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 standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with orbital messaging, check-in and emergency SOS for when you’re out of coverage.

Outcome is an increasingly remarkable outdoor tool for those that want to be unplugged. If you wish to have someone keep an eye on you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without requiring additional gear.

This is quite freeing to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal cost of the watch and the monthly subscription of the inReach service to provide the features. At least it is not dependent on your phone provider so works with all make of smartphone and network.

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

Advantages: LTE and orbital communication, high-luminance OLED display, tracks everything with premier GPS, integrated flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and satellite functions need ongoing payment, restricted Garmin Pay financial compatibility, voice features are slow, limited wearable features compared with competing watches.
