Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for Phone-Free Messaging

The newest version of Garmin's flagship Fenix adventure watch introduces a potentially lifesaving capability: phone-free messaging and emergency messaging using 4G LTE or orbital links.

This Fenix 8 Pro enhances the already impressive Fenix 8 by incorporating new cellular technology, plus an optional advanced microLED screen in a special edition. It is Garmin's premier device and engineered to be the single gadget required to venture almost anywhere and track every activity.

This makes it an very expensive option, priced from £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 edition with microLED display – nearly double the price of the standard Fenix 8.

You do get a significant features for your money, with industry-leading fitness, movement and adventure monitoring. The complete offline mapping of the world can automatically guide you back to the path if you lose your way without a phone, and look great on the sizable, crisp and super-bright display.

This Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the smaller 43mm version found in other models, so it is a large watch for bigger wrists. But the 47mm OLED version as reviewed does have an additional day of smartwatch battery life even with the display always active, enduring a reliable eight to nine days between charging.

Phone-Free Texting, Calling and Real-Time Location

Garmin uses its proprietary inReach LTE (4G) and orbital service service instead of relying on a watch plan tied to your mobile carrier, as with other smartwatches. However in contrast to Apple or Google's satellite-capable devices, SOS communication is not included for no cost.

Instead, subscriptions start at £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, calls and LiveTrack position sharing – so your friends or family can keep an eye on you while out running, cycling or similar activities – along with SOS orbital SOS alerts.

Location updates and texts over satellite are then billed additionally, with more expensive plans including various quotas of orbital usage, climbing to a £50 a month all-inclusive plan. The watch comes with a 30-day free trial so you can evaluate the functionality.

After you have got it set up, you just head out outside without your phone and the watch will link to LTE. You can not use it for playing music or comparable tasks, but you can place and receive calls, send texts and overall keep in touch with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they download the Garmin Messenger app, you can then message reciprocally using typed or spoken communications, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, just a mobile number is sufficient to sign up for texts.

Texting on the watch works adequately but composing texts on the tiny on-screen keyboard is time-consuming. It includes a collection of personalizable canned responses you can send to speed things up. Voice recordings and calls work OK, though as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the quality is not fantastic.

LiveTrack is the handiest function. You can set it up to on its own transmit a link to selected contacts every time you start an activity, so they can follow your real time location on a map. It’s great for following race performance, but it primarily acts as a utility for someone you rely on to know your location in case an incident occurs. It has generally functioned well, though the actual location has occasionally been delayed when transitioning in and out of good LTE signal.

These features are available on other Garmin devices if you carry your phone with you, but in locations where LTE does not reach, the orbital 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 orbital system, which then transmits and gets messages within about 10 to 30 seconds. It was surprisingly easy to use and could be a crucial lifeline, though it is important to remember that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is typically repairable with options available via the support site. The battery is certified to maintain at least 90% of its original capacity after two years of weekly charging. The watch does not contain any reused materials. Garmin provides disposal programs on recent 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 service packages cost from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

This Fenix 8 Pro takes a excellent outdoor watch in the standard Fenix 8 and incorporates LTE for messaging, calls and LiveTrack – plus orbital messaging, location update and emergency SOS for when you’re without signal.

The result is an even more impressive adventure tool for those that want to be phone-free. If you wish to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

This is very liberating to be outdoors without a phone, but that capability comes at a significant cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the features. Fortunately it isn’t dependent on your phone carrier so works with all make of smartphone and network.

The Fenix 8 Pro is a killer gadget for someone who hates being weighed down by their phone when running, cycling or hiking, but still desires to be locatable and contactable. For everyone else, it is a lot of expense when the superb Fenix 8 is already available.

Pros: LTE and orbital communication, high-luminance OLED screen, tracks everything with premier GPS, integrated flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: very expensive, LTE and satellite features require ongoing payment, limited Garmin Pay financial compatibility, voice features are sluggish, limited wearable features compared with Apple/Google/Samsung watches.
