The Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for Phone-Free Texting

This most recent model of Garmin's premium Fenix adventure timepiece includes a potentially lifesaving feature: phone-free communication and emergency messaging via 4G LTE or satellite connections.

This Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating new mobile technology, plus an optional state-of-the-art microLED display in a limited edition. It is Garmin's premier device and designed to be the single gadget required to venture virtually anywhere and monitor all your movements.

This makes it an extremely expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – nearly double the cost of the standard Fenix 8.

Users receive a lot of features for your investment, with best-in-class fitness, activity and adventure tracking. The full offline mapping of the world can seamlessly guide you back to the path if you get lost without a phone, and look excellent on the large, sharp and high-luminance display.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other devices, so it is a big watch for bigger wrists. However the 47mm OLED version as tested does have an additional day of smartwatch battery life even with the display on all the time, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

The company uses its proprietary inReach LTE (4G) and orbital subscription plan rather than relying on a watch plan linked to your mobile provider, like other smartwatches. But unlike competing satellite-capable products, emergency messaging is not provided for free.

Rather, plans begin from £7.99 or equivalent a month, which provides limitless LTE SMS and audio messages, calls and LiveTrack location sharing – so your contacts or loved ones can monitor you while engaged in jogging, biking or similar activities – plus SOS orbital SOS alerts.

Check-ins and texts via orbital are then charged on top, with higher-tier subscriptions offering different allowances of satellite usage, increasing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can test out the service.

After you have got it set up, you just venture outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you can make and take calls, send texts and generally keep in touch with your family and companions.

When 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 application, you can then communicate back and forth via text or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Messaging on the watch functions adequately but typing out 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 acceptably, though as with most wearables, you’re not going to want to use it for lengthy conversations as the audio clarity is less than fantastic.

LiveTrack is the most useful feature. You can configure to on its own transmit a link to chosen contacts every time you begin an activity, so they can track your live location on a map. It’s great for following competition progress, but it mostly acts as a utility for someone you rely on to know your whereabouts in case an incident occurs. It has generally functioned well, although the real position has occasionally lagged when transitioning in and out of good LTE coverage.

These features are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A guide shows you how to find the clear view to the satellite, 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 remember that satellite coverage is limited to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally repairable with options available through the customer service site. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin offers disposal schemes on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – along with orbital communication, check-in and emergency SOS for when you’re without signal.

The result is an increasingly remarkable outdoor device for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin accomplishes this without requiring anything else.

It is very freeing to be outdoors without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the monthly subscription of the inReach service to enable the service. Fortunately it is not dependent on your phone provider so functions with any brand of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who dislikes being weighed down by their phone when running, biking or hiking, but nevertheless wants to be locatable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 already exists.

Pros: LTE and satellite messaging, super-bright OLED screen, tracks all activities with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite features need monthly payment, limited Garmin Pay financial compatibility, speech features are sluggish, basic smartwatch features compared with Apple/Google/Samsung watches.
