Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Communication for No-Phone Texting

The most recent model of Garmin's premium Fenix adventure watch introduces a potentially lifesaving feature: no-phone communication and SOS alerts via 4G LTE or orbital links.

The Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new mobile tech, plus an available advanced microLED display in a limited edition. This is the brand's top model and engineered to be the single gadget needed to explore almost any location and monitor all your movements.

That positions it as an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the standard Fenix 8.

Users receive a significant features for your money, with industry-leading workout, movement and outdoor monitoring. The full offline mapping of the world can automatically guide you return to the path if you lose your way absent a phone, and appear great on the sizable, crisp and high-luminance display.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm version found in other models, so it is a big watch for bigger wrists. But the 47mm OLED version as tested boasts an extra day of watch battery life despite the display always active, lasting a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and satellite subscription service rather than relying on a watch plan linked to your phone carrier, as with other wearables. However unlike competing satellite-enabled devices, SOS messaging is not provided for free.

Instead, subscriptions begin from £7.99 or similar a month, which provides limitless LTE SMS and voice messages, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while engaged in jogging, biking or similar activities – plus emergency satellite SOS alerts.

Check-ins and texts via orbital are then billed additionally, with more expensive plans including various allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out the functionality.

Once you have completed setup, you simply head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can place and receive calls, dispatch texts and generally stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a random number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate reciprocally via text or voice messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger app, just a phone number is enough to sign up for texts.

Texting on the watch functions adequately but typing out texts on the tiny on-screen keyboard is slow. It includes a set of personalizable canned replies you can send to speed things up. Spoken recordings and calls work OK, although as with most smartwatches, you’re not going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the handiest function. You can set it up to automatically transmit a URL to chosen contacts whenever you start an exercise, so they can track your real time position on a map. It’s excellent for following race progress, but it primarily serves as a tool for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned well, though the actual location has sometimes been delayed when transitioning in and out of good LTE signal.

These features are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to transmit texts, position updates and SOS SOS.

A guide displays you how to locate the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly easy to use and could be a vital lifeline, however it is important to note that satellite coverage is limited to the US continent, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options available through the customer service portal. The battery is certified to retain 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 recent purchases.

Cost

The Fenix 8 Pro costs 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

This Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus satellite messaging, check-in and SOS SOS for when you’re out of coverage.

Outcome is an increasingly impressive outdoor device for those that want to be phone-free. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin does so without requiring anything else.

This is quite liberating to be outdoors without a phone, but that functionality comes at quite a cost, both in terms of the colossal cost of the watch and the recurring subscription of the inReach service to enable the service. Fortunately it isn’t reliant on your phone carrier so works with all make of smartphone and carrier.

The Fenix 8 Pro is a killer device for someone who hates being weighed down by their phone when running, biking or trekking, but still wants to be trackable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, super-bright OLED screen, tracks all activities with premier GPS, integrated flashlight, phone and standalone voice control, 8+ day battery life, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre waterproofing and 40-metre underwater use, physical controls and touchscreen.

Drawbacks: very costly, LTE and satellite functions need ongoing subscription, limited Garmin Pay financial support, voice features are slow, limited smartwatch features versus Apple/Google/Samsung watches.
