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

This most recent iteration of the top-tier Fenix outdoor timepiece brings a life-saving capability: phone-free messaging and SOS messaging using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new mobile tech, plus an optional state-of-the-art microLED display in a limited edition. This is the brand's top model and engineered to be the single gadget required to explore virtually anywhere and monitor every activity.

That makes it an very pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching 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.

Users receive a significant features for your money, with best-in-class workout, activity and adventure monitoring. The full offline maps of the world can seamlessly guide you back to the path if you lose your way without a phone, and appear great on the large, crisp and high-luminance touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm size available in other devices, so it is a large watch for larger wrists. But the 47mm OLED model as tested does have an additional day of watch battery life even with the display on all the time, enduring a reliable eight to nine days between charging.

No-Phone Texting, Calling and Real-Time Location

The company uses its own inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan tied to your mobile carrier, like other wearables. But in contrast to Apple or Google's satellite-capable products, SOS communication is not provided for free.

Rather, subscriptions begin from £7.99 or similar a month, which includes limitless LTE SMS and audio messages, calls and LiveTrack position tracking – so your contacts or family can monitor you while out jogging, biking or similar activities – along with SOS orbital SOS alerts.

Location updates and messages via orbital are then billed on top, with more expensive plans offering various quotas of satellite use, climbing to a £50 a month unlimited plan. The watch includes a 30-day free trial so you can test out the service.

Once you have got it set up, you simply head out the door without your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you are able to make and take calls, dispatch texts and generally stay connected with your family and companions.

Whenever you text someone, Garmin dispatches them an SMS from a random phone number, which they can reply to directly to your watch. If they download the Garmin Messenger application, you can then message back and forth using text or spoken messages, and initiate voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, only a phone number is sufficient to register for texts.

Texting on the watch functions fine 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 recordings and calls work acceptably, though as with most wearables, you’re not going to wish to use it for lengthy conversations as the quality is not ideal.

LiveTrack is the most useful feature. You can set it up to automatically send a link to chosen contacts every time you start an exercise, so they can track your real time location on a map. It’s excellent for following competition performance, but it primarily acts as a tool for someone you trust to know your location in case something happens. It has typically functioned well, although the real position has occasionally been delayed when transitioning in and out of good LTE signal.

All of these features are available on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, 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 transmits and gets messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, however it is essential to remember that satellite coverage is limited to the US continent, most of Canada, and most of Europe except for regions of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with services available through the support portal. The battery is rated to retain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin offers recycling programs on new purchases.

Price

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

Verdict

The Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with satellite messaging, location update and SOS SOS for when you’re without coverage.

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

This is very liberating to be outdoors without a phone, but that functionality carries quite a price, both in terms of the colossal price of the watch and the monthly subscription of the inReach service to provide the service. At least it isn’t dependent on your phone provider so functions with any make of smartphone and carrier.

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

Advantages: LTE and satellite communication, high-luminance OLED display, tracks all activities with best-in-class GPS, integrated flashlight, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Drawbacks: very costly, LTE and satellite functions need ongoing subscription, limited Garmin Pay bank support, speech features are sluggish, basic wearable features compared with Apple/Google/Samsung watches.
