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

This most recent iteration of Garmin's premium Fenix adventure watch brings a potentially lifesaving feature: no-phone communication and SOS messaging via 4G LTE or orbital links.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new mobile technology, plus an optional state-of-the-art microLED display in a special edition. This is Garmin's premier model and engineered to be the single gadget needed to explore almost anywhere and track all your movements.

That makes it an very expensive option, 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 twice the cost of the regular Fenix 8.

Users receive a significant functionality for your money, with best-in-class fitness, movement and outdoor monitoring. Its full offline maps of the globe can seamlessly guide you back to the trail if you lose your way absent 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 smaller 43mm size available in other models, so it is a big watch for larger wrists. However the 47mm OLED version as tested boasts an extra day of smartwatch battery life despite the screen always active, lasting a solid eight to nine days between charges.

Phone-Free Texting, Calling and Real-Time Location

Garmin operates its proprietary inReach LTE (4G) and orbital subscription service rather than relying on a watch plan tied to your mobile carrier, as with other smartwatches. But in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for free.

Rather, subscriptions start at £7.99 or equivalent a month, which includes unlimited LTE text and voice messages, call functionality and LiveTrack location sharing – so your friends or family can monitor you while out running, cycling or similar pursuits – along with emergency satellite SOS messaging.

Location updates and texts via orbital are then billed on top, with more expensive subscriptions offering different allowances of satellite use, increasing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can evaluate the functionality.

Once you have completed setup, you just head out the door minus your phone and the watch will connect to LTE. You cannot use it for streaming music or similar activities, but you are able to make and take calls, dispatch texts and overall stay connected with your relatives and companions.

When you text someone, Garmin sends them an SMS from a random phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally via typed or voice messages, and make voice calls. Your contact is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a set of personalizable canned responses you can use to expedite communication. Spoken messages and calls work acceptably, though as with the majority of wearables, you’re not going to want to use it for lengthy conversations as the quality is less than 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 real time position on a map. It’s great for following competition performance, but it mostly acts as a tool for someone you rely on to know your whereabouts in case something happens. It has typically worked well, though the actual location has occasionally lagged when transitioning in and out of good LTE coverage.

These capabilities are available on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A guide shows you how to locate the clear view to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, however it is important to note that orbital coverage is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is typically serviceable with options available through the support site. The battery is certified to maintain at least 90% of its initial power after two years of weekly charging. The watch does not contain any recycled components. Garmin offers disposal programs on new purchases.

Price

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

Verdict

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re without coverage.

The result is an increasingly impressive adventure device for those that want to be unplugged. If you want to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outside without a phone, but that capability carries a significant cost, both in terms of the substantial cost of the watch and the recurring fee of the inReach service to enable the service. At least it is not reliant on your phone provider so functions with all make of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when jogging, cycling or trekking, but still desires to be trackable and reachable. For other users, it is a lot of money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED display, monitors all activities with best-in-class GPS, integrated torch, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: very costly, LTE and satellite functions require monthly payment, restricted Garmin Pay financial support, voice capabilities are slow, basic smartwatch functionality compared with competing watches.
