The Fenix 8 Pro Review: Integrated LTE and Satellite Connectivity for No-Phone Messaging

The most recent version of Garmin's flagship Fenix adventure timepiece includes a life-saving capability: phone-free communication and emergency messaging using 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by incorporating new mobile technology, along with an optional advanced microLED display in a limited edition. It is Garmin's top model and engineered to be the single tool needed to explore almost any location and track every activity.

This positions it as an very pricey proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the price of the regular Fenix 8.

You do receive a lot of features for your money, with best-in-class workout, movement and outdoor tracking. The complete offline mapping of the world can automatically guide you return to the trail if you get lost absent a phone, and look great on the large, sharp and high-luminance touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as tested boasts an additional day of smartwatch battery life despite the screen on all the time, lasting a reliable eight to nine days between charges.

Phone-Free Messaging, Calling and Real-Time Location

The company operates its proprietary inReach LTE (4G) and orbital service plan rather than depending on a watch plan linked to your phone carrier, as with other wearables. However unlike Apple or Google's satellite-enabled products, emergency messaging is not included for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes unlimited LTE text and audio messaging, call functionality and LiveTrack position sharing – so your contacts or loved ones can monitor you while out running, cycling or similar pursuits – along with emergency orbital SOS messaging.

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

After you have got it set up, you just head out the door without your phone and the watch will link to LTE. You can not use it for playing music or comparable activities, but you can place and receive calls, send texts and overall stay connected with your relatives and friends.

When you text someone, Garmin sends them an SMS from a random phone number, which they can reply to directly to your watch. If they install the Garmin Messenger app, you can then communicate back and forth via text or spoken messages, and initiate voice calls. Your recipient does not need a Garmin account to use the Messenger app, just a phone number is enough to sign up for texts.

Messaging on the watch functions fine but typing out texts on the small on-screen keyboard is slow. It includes a set of customisable canned responses you can send to expedite communication. Spoken recordings and calls work acceptably, although as with the majority of smartwatches, you’re unlikely going to want to use it for lengthy conversations as the quality is less than fantastic.

LiveTrack is the most useful feature. You can configure to automatically send a link to chosen contacts every time you start an activity, so they can follow your live position on a map. It’s excellent for monitoring competition progress, but it mostly serves as a utility for someone you trust to be aware of your location in case an incident occurs. It has typically worked effectively, although the actual position has occasionally been delayed when transitioning in and out of good LTE coverage.

These features are accessible on other Garmin devices if you carry your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to send texts, position updates and SOS SOS.

A guide displays you how to find the line of sight to the orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital lifeline, though it is important to note that orbital service is limited to the US continent, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically repairable with services available via the customer service portal. The battery is certified to retain at least 90% of its initial capacity after two years of regular charging. The watch lacks any reused materials. Garmin offers disposal programs on new purchases.

Price

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

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the regular Fenix 8 and incorporates LTE for messaging, call functionality and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re without coverage.

The result is an increasingly impressive outdoor tool for those that want to be phone-free. If you wish to have someone keep an eye on you remotely while exercising after dark or in the middle of nowhere, 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 price, both in terms of the substantial price 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 all brand of smartphone and carrier.

The Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when running, biking or hiking, but nevertheless wants to be locatable and reachable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and orbital messaging, super-bright OLED display, tracks everything with best-in-class GPS, built-in torch, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: very expensive, LTE and satellite features require monthly subscription, limited Garmin Pay financial support, speech features are sluggish, limited wearable functionality versus Apple/Google/Samsung watches.
