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

This latest version of the top-tier Fenix adventure timepiece introduces a life-saving feature: no-phone messaging and emergency messaging using 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already impressive Fenix 8 by adding new cellular technology, along with an optional advanced microLED screen in a limited edition. This is the brand's top model and engineered to be the single gadget needed to venture almost anywhere and track every activity.

This makes it an extremely expensive proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the price of the standard Fenix 8.

Users receive a significant functionality for your investment, with industry-leading fitness, activity and outdoor monitoring. Its complete offline maps of the globe can automatically guide you back to the path if you get lost absent a phone, and look great on the sizable, sharp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other devices, so it is a big watch for larger wrists. But the 47mm OLED model as tested boasts an extra day of smartwatch battery life even with the display on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital service service instead of depending on a watch plan tied to your mobile carrier, like other smartwatches. However unlike competing satellite-capable products, SOS messaging is not provided for no cost.

Rather, plans start at £7.99 or similar a month, which includes limitless LTE SMS and audio messaging, call functionality and LiveTrack position sharing – so your friends or family can keep an eye on you while engaged in running, biking or similar pursuits – along with SOS satellite SOS messaging.

Location updates and messages via satellite are then charged on top, with higher-tier plans including various allowances of satellite use, climbing to a £50 a month all-inclusive subscription. The watch includes a 30-day trial period so you can test out the service.

After you have completed setup, you simply venture outside minus your phone and the watch will link to LTE. You cannot use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and overall stay connected with your relatives and companions.

Whenever you text someone, Garmin sends them an SMS from a random phone number, which they can reply to back to your watch. If they download the Garmin Messenger application, you can then communicate reciprocally using typed or voice messages, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a phone number is sufficient to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is slow. It has a collection of personalizable pre-set replies you can send to expedite communication. Spoken recordings and calls perform OK, though as with the majority of wearables, you’re unlikely going to want to use it for lengthy conversations as the audio clarity is not fantastic.

LiveTrack is the most useful function. You can configure to on its own transmit a link to chosen contacts whenever you begin an activity, so they can track your real time position on a map. It’s excellent for monitoring competition performance, but it mostly serves as a utility for someone you trust to know your location in case something happens. It has typically worked well, though the real position has sometimes lagged when moving in and out of strong LTE coverage.

All of these capabilities are available on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, location updates and emergency SOS.

A on-screen assistance shows you how to find the line of sight to the orbital system, which then transmits and gets communications within about 10 to 30 seconds. It was surprisingly straightforward to use and could be a vital safety feature, though it is important to note that orbital coverage is restricted to the US mainland, the majority of Canada, and most of Europe except for parts of Scandinavia above 65 degrees latitude.

Sustainability

The watch is generally repairable with options offered through the support site. The battery is certified to retain at least 90% of its initial capacity after two years of weekly charging. The watch lacks any reused materials. Garmin provides recycling schemes on new purchases.

Cost

This Fenix 8 Pro is priced 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 takes a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite communication, check-in and SOS SOS for when you’re out of coverage.

Outcome is an increasingly impressive outdoor tool for those that desire to be phone-free. If you wish to have someone keep an eye on you remotely while running after dark or in the middle of nowhere, the Garmin accomplishes this without requiring anything else.

This is very liberating to be outside without a phone, but that functionality carries a significant cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach service to enable the features. Fortunately it is not reliant on your phone provider so works with any 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, biking or trekking, but nevertheless wants to be trackable and contactable. For everyone else, it is a significant money when the excellent Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED display, monitors all activities with best-in-class GPS, built-in flashlight, phone and standalone voice control, 8+ day endurance, Garmin Pay, complete offline mapping and navigation, offline Spotify, 100-metre waterproofing and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and orbital features require ongoing payment, restricted Garmin Pay financial support, voice capabilities are slow, limited smartwatch functionality compared with competing watches.
