Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Connectivity for No-Phone Texting

This newest version of Garmin's flagship Fenix outdoor timepiece brings a life-saving feature: phone-free communication and SOS alerts via 4G LTE or orbital links.

This Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding cutting-edge mobile technology, plus an optional state-of-the-art microLED display in a special edition. It is Garmin's premier model and designed to be the single tool required to explore almost anywhere and track every activity.

That makes it an extremely expensive proposition, 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 screen – almost twice the cost of the standard Fenix 8.

You do get a lot of features for your money, with industry-leading workout, movement and adventure monitoring. The complete offline mapping of the globe can seamlessly guide you back to the trail if you lose your way without a phone, and appear excellent on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the smaller 43mm size available in other devices, so it is a big watch for bigger wrists. But the 47mm OLED version as tested boasts an additional day of smartwatch battery life even with the screen always active, enduring a reliable eight to nine days between charges.

Phone-Free Texting, Calls and Live Tracking

The company uses its proprietary inReach LTE (4G) and satellite service service rather than relying on a watch plan tied to your mobile provider, like other smartwatches. But unlike competing satellite-capable devices, emergency messaging is not provided for no cost.

Instead, plans start at £7.99 or equivalent a month, which includes limitless LTE SMS and audio messages, calls and LiveTrack location tracking – so your contacts or family can keep an eye on you while out jogging, cycling or comparable activities – along with SOS satellite SOS messaging.

Check-ins and texts over satellite are then charged additionally, with more expensive plans offering various quotas of satellite use, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day trial period so you can evaluate the functionality.

After you have got it set up, you just venture the door without your phone and the watch will link to LTE. You cannot use it for playing music or comparable activities, but you are able to make and take calls, send texts and overall stay connected 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 app, you can then message back and forth using typed or voice messages, and make voice calls. Your recipient is not required to have a Garmin profile to use the Messenger application, just a mobile number is enough to register for texts.

Texting on the watch functions fine but typing out texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable canned responses you can use to speed things up. Spoken messages and calls perform acceptably, although as with most smartwatches, you’re not going to want to use it for extended conversations as the audio clarity is not ideal.

LiveTrack is the most useful function. You can configure to automatically send a link to chosen contacts whenever you begin an exercise, so they can follow your real time position on a map. It’s great for following race progress, but it mostly serves as a utility for someone you rely on to be aware of your whereabouts in case something happens. It has generally functioned well, although the real position has sometimes been delayed when moving in and out of strong LTE signal.

All of these capabilities are available on other Garmin watches if you carry your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital lifeline, though it is essential to note that orbital coverage is limited to the US mainland, most of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees north.

Environmental Impact

The watch is generally serviceable with options available via the customer service site. The battery is certified 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.

Cost

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 cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro builds on a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re out of signal.

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 exercising out at night or in the middle of nowhere, the Garmin does so without needing additional gear.

It is quite freeing to be outside without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the recurring fee of the inReach plan to provide the features. Fortunately it is not reliant on your phone provider so works with all brand of smartphone and network.

This Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when jogging, cycling or hiking, but still desires to be trackable and contactable. For other users, it is a lot of money when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED display, monitors everything with best-in-class GPS, integrated torch, voice and standalone voice control, 8+ day endurance, Garmin Pay, complete offline maps and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, buttons and touch.

Cons: very expensive, LTE and orbital functions require ongoing subscription, limited Garmin Pay financial support, speech capabilities are sluggish, basic wearable features versus Apple/Google/Samsung watches.
