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

This latest version of Garmin's flagship Fenix outdoor watch includes a life-saving capability: phone-free messaging and emergency alerts via 4G LTE or orbital connections.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by adding new mobile tech, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's top model and engineered to be the single gadget needed to explore virtually anywhere and monitor every activity.

That positions it as an extremely pricey option, priced from £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 edition with microLED screen – nearly twice the price of the regular Fenix 8.

Users receive a significant features for your investment, with best-in-class workout, activity and outdoor tracking. The complete offline maps of the globe can automatically direct you return to the trail if you lose your way without a phone, and look great on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other models, so it is a large watch for larger wrists. But the 47mm OLED model as reviewed boasts an additional day of smartwatch battery life despite 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 satellite subscription plan rather than depending on a watch plan tied to your phone carrier, like other smartwatches. However in contrast to Apple or Google's satellite-capable devices, emergency messaging is not included for no cost.

Rather, subscriptions begin from £7.99 or similar a month, which includes unlimited LTE SMS and audio messaging, calls and LiveTrack position sharing – so your friends or family can keep an eye on you while engaged in running, biking or similar activities – plus SOS satellite SOS alerts.

Location updates and messages via orbital are then billed on top, with more expensive plans offering various allowances of orbital usage, climbing to a £50 a month unlimited subscription. The watch comes with a 30-day trial period so you can evaluate the service.

Once you have got it set up, you simply venture outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you can make and take calls, dispatch texts and overall stay connected with your family and friends.

Whenever you text someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they download the Garmin Messenger app, you can then message reciprocally using text or voice communications, and initiate voice calls. Your contact is not required to have a Garmin account to use the Messenger app, only a mobile number is sufficient to sign up for texts.

Messaging on the watch works adequately but composing texts on the small on-screen keyboard is time-consuming. It has a set of personalizable pre-set replies you can use to expedite communication. Voice messages and calls perform OK, though as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the handiest function. You can configure to on its own send a URL to chosen contacts whenever you start an exercise, so they can follow your live position on a map. It’s excellent for following competition performance, but it primarily serves as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has typically functioned well, although the real location has occasionally been delayed when transitioning in and out of strong LTE coverage.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, position check-ins and emergency SOS.

A guide shows 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 surprisingly easy to use and could be a vital lifeline, though it is essential to note that satellite service is restricted to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is typically repairable with services available via the customer service site. The battery is rated to maintain at least 90% of its initial power after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling programs on new 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 packages begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re without coverage.

The result is an even more remarkable outdoor device for those that want to be unplugged. If you want to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing anything else.

This is very freeing to be outside without a phone, but that capability carries quite a cost, both in terms of the colossal cost of the watch and the monthly fee of the inReach plan to enable the service. Fortunately it is not dependent on your phone provider so functions with all brand of smartphone and network.

This 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 reachable. For other users, it is a lot of expense when the superb Fenix 8 already exists.

Pros: LTE and orbital communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, voice and standalone voice control, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Drawbacks: very costly, LTE and orbital features require monthly subscription, limited Garmin Pay bank compatibility, speech features are slow, basic wearable features compared with Apple/Google/Samsung watches.
