Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Messaging

The latest version of the top-tier Fenix adventure timepiece brings a potentially lifesaving capability: phone-free communication and emergency alerts using 4G LTE or satellite connections.

This Fenix 8 Pro builds upon the previously impressive Fenix 8 by incorporating new mobile tech, along with an optional state-of-the-art microLED screen in a special edition. It is Garmin's premier model and engineered to be the only tool required to venture almost anywhere and track all your movements.

That makes it an very expensive proposition, starting at £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 display – almost double the cost of the standard Fenix 8.

Users receive a significant features for your investment, with industry-leading fitness, movement and outdoor tracking. The full offline maps of the world can automatically guide you back to the path if you lose your way absent a phone, and look great on the large, sharp and super-bright touchscreen.

The Fenix 8 Pro is only offered in 47mm or 51mm case sizes, omitting the more compact 43mm version available in other devices, so it is a large watch for bigger wrists. However the 47mm OLED model as reviewed does have an additional day of smartwatch battery life even with the display on all the time, lasting a solid eight to nine days between charging.

Phone-Free Messaging, Calls and Live Tracking

Garmin operates its proprietary inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan tied to your mobile carrier, like other smartwatches. But unlike competing satellite-capable devices, SOS communication is not provided for no cost.

Rather, plans start at £7.99 or similar a month, which provides limitless LTE text and voice messaging, calls and LiveTrack location tracking – so your contacts or family can monitor you while engaged in jogging, biking or comparable pursuits – plus emergency satellite SOS alerts.

Check-ins and texts over orbital are then charged additionally, with more expensive plans offering different allowances of satellite usage, increasing to a £50 a month unlimited subscription. The watch includes a 30-day free trial so you can test out the service.

After you have got it set up, you just venture outside minus your phone and the watch will link to LTE. You cannot use it for playing music or comparable tasks, but you can place and receive calls, dispatch texts and generally keep in touch with your relatives and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary phone number, which they can reply to back to your watch. If they install the Garmin Messenger app, you can then message back and forth via text or spoken messages, and initiate voice calls. Your contact is not required to have a Garmin profile to use the Messenger application, only a mobile number is enough to sign up for texts.

Texting on the watch works fine but composing texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable canned responses you can send to speed things up. Spoken recordings and calls perform acceptably, although as with the majority of smartwatches, you’re unlikely going to wish to use it for extended discussions as the audio clarity is not ideal.

LiveTrack is the most useful function. You can set it up to on its own send a URL to selected contacts every time you begin an exercise, so they can follow your live position on a map. It’s excellent for monitoring competition performance, but it mostly serves as a utility for someone you rely on to know your whereabouts in case something happens. It has typically worked well, although the actual position has occasionally lagged when moving in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin watches if you bring your phone with you, but in locations where LTE does not reach, the satellite kicks in on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A guide shows you how to locate the line of sight to the orbital system, which then sends and receives messages within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a crucial lifeline, however it is essential to note that satellite service is restricted to the US mainland, the majority of Canada, and most of Europe excluding regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with options offered via the customer service portal. The battery is rated to maintain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any recycled materials. Garmin provides recycling programs on recent purchases.

Cost

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

Verdict

The Fenix 8 Pro takes a excellent adventure watch in the standard Fenix 8 and adds LTE for texting, calls and LiveTrack – plus orbital communication, location update and emergency SOS for when you’re without signal.

Outcome is an increasingly impressive outdoor tool for those that want to be unplugged. If you wish to have someone keep an eye on you remotely while running out at night or in the remote areas, the Garmin does so without needing additional gear.

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

This Fenix 8 Pro is a top-tier device for someone who hates being burdened by their phone when jogging, cycling or trekking, but nevertheless desires to be locatable and reachable. For everyone else, it is a significant expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital communication, high-luminance OLED screen, monitors everything with best-in-class GPS, built-in torch, phone and standalone commands, 8+ day battery life, Garmin Pay, full offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Drawbacks: extremely costly, LTE and orbital functions need monthly payment, limited Garmin Pay bank support, voice features are sluggish, basic smartwatch functionality compared with competing watches.
