Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for Phone-Free Texting

The most recent version of Garmin's flagship Fenix adventure timepiece includes a life-saving feature: no-phone communication and emergency alerts using 4G LTE or satellite links.

This Fenix 8 Pro upgrades the already impressive Fenix 8 by incorporating new cellular tech, plus an optional advanced microLED screen in a limited edition. This is Garmin's top model and engineered to be the single tool needed to venture virtually anywhere and track every activity.

This makes it an very expensive option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – almost twice the cost of the regular Fenix 8.

You do receive a lot of functionality for your money, with industry-leading workout, activity and outdoor monitoring. Its full offline mapping of the world can seamlessly direct you return to the trail if you get lost without a phone, and appear excellent on the large, crisp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the smaller 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed boasts an extra day of smartwatch battery life despite the display always active, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calls and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service instead of depending on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-enabled products, emergency messaging is not included for free.

Rather, subscriptions begin from £7.99 or equivalent a month, which includes unlimited LTE SMS and voice messages, calls and LiveTrack position sharing – so your contacts or family can monitor you while engaged in jogging, biking or comparable pursuits – plus SOS satellite SOS alerts.

Check-ins and messages over satellite are then charged on top, with more expensive plans offering various quotas of satellite use, increasing to a £50 a month all-inclusive subscription. The watch comes with a 30-day trial period so you can test out the service.

Once you have got it set up, you just head out outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable activities, but you can place and receive calls, send texts and generally stay connected with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message back and forth via typed or voice messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, only a phone number is sufficient to sign up for texts.

Texting on the watch works fine but composing texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable pre-set responses you can use to expedite communication. Spoken recordings and calls work OK, although as with most wearables, you’re unlikely going to want to use it for extended discussions as the audio clarity is less than fantastic.

LiveTrack is the handiest function. You can configure to on its own transmit a URL to chosen contacts every time you begin an activity, so they can track your real time location on a map. It’s great for following competition performance, but it primarily serves as a utility for someone you trust to know your location in case something happens. It has generally worked well, though the real position has occasionally been delayed when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the satellite kicks in on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A guide displays you how to find 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 crucial safety feature, though it is important to note that satellite coverage is restricted to the US continent, the majority of Canada, and the majority of Europe except for parts of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with services available through the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers recycling programs on new purchases.

Cost

The Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The additional 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 regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and SOS SOS for when you’re out of coverage.

Outcome is an even more remarkable adventure tool for those that want to be unplugged. If you want to have someone monitor you remotely while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outside without a phone, but that functionality carries a significant price, both in terms of the substantial cost of the watch and the recurring subscription of the inReach service to provide the features. At least it is not reliant on your phone carrier so functions with all make of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when jogging, biking or trekking, but nevertheless desires to be locatable and contactable. For other users, it is a lot of money when the excellent Fenix 8 is already available.

Pros: LTE and satellite communication, super-bright OLED screen, tracks everything with best-in-class GPS, integrated flashlight, voice and offline voice control, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and satellite features need ongoing subscription, restricted Garmin Pay financial compatibility, speech capabilities are sluggish, limited wearable features compared with competing watches.
