Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Connectivity for Phone-Free Texting

This most recent model of the flagship Fenix outdoor timepiece introduces a potentially lifesaving capability: no-phone communication and SOS alerts using 4G LTE or orbital connections.

This Fenix 8 Pro enhances the already outstanding Fenix 8 by adding cutting-edge cellular tech, along with an optional advanced microLED screen in a limited edition. This is Garmin's premier model and engineered to be the only gadget needed to venture virtually any location and track every activity.

That positions it as an very expensive proposition, priced from £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 price of the regular Fenix 8.

Users get a lot of functionality for your money, with best-in-class workout, activity and outdoor tracking. Its full offline maps of the world can seamlessly guide you return to the path if you get lost absent a phone, and look great on the large, sharp and high-luminance touchscreen.

This Fenix 8 Pro is exclusively offered in 47mm or 51mm case dimensions, not the smaller 43mm version found in other models, so it is a big watch for bigger wrists. However the 47mm OLED version as tested does have an additional day of smartwatch battery life even with the screen always active, lasting a solid eight to nine days between charges.

No-Phone Messaging, Calls and Live Tracking

Garmin operates its own inReach LTE (4G) and orbital service plan instead of depending on a watch plan tied to your phone provider, as with other wearables. But in contrast to Apple or Google's satellite-enabled devices, SOS communication is not included for free.

Rather, plans begin from £7.99 or similar a month, which provides unlimited LTE SMS and audio messages, call functionality and LiveTrack position tracking – so your friends or family can keep an eye on you while out jogging, cycling or similar pursuits – plus SOS satellite SOS alerts.

Location updates and texts via orbital are then billed on top, with more expensive subscriptions offering different quotas of orbital usage, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day free trial so you can test out the functionality.

Once you have got it set up, you just venture outside minus your phone and the watch will connect to LTE. You can not use it for playing music or comparable tasks, but you are able to place and receive calls, dispatch texts and overall stay connected with your family and friends.

When you text someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they download the Garmin Messenger application, you can then message reciprocally via text or voice communications, and initiate voice calls. Your contact does not need a Garmin profile to use the Messenger application, only a mobile number is enough to register for texts.

Texting on the watch works adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable canned responses you can use to expedite communication. Voice recordings and calls work OK, although as with most smartwatches, you’re unlikely going to want to use it for lengthy conversations as the quality is less than ideal.

LiveTrack is the handiest feature. You can set it up to on its own transmit a URL to chosen contacts every time you begin an exercise, so they can follow your live location on a map. It’s great for monitoring race 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 functioned well, although the real position has occasionally lagged when moving in and out of strong LTE coverage.

All of these features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE does not reach, the orbital activates on the Fenix 8 Pro to transmit texts, position check-ins and SOS SOS.

A on-screen assistance displays you how to locate the clear view to the satellite, which then sends and receives 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 coverage is restricted to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is generally serviceable with options offered via the support portal. The battery is certified to maintain at least 90% of its initial capacity after two years of weekly charging. The watch does not contain any recycled components. Garmin offers disposal schemes on recent purchases.

Cost

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

Verdict

This Fenix 8 Pro builds on a excellent adventure watch in the regular Fenix 8 and adds LTE for messaging, calls and LiveTrack – plus satellite communication, location update and emergency SOS for when you’re without signal.

Outcome is an increasingly remarkable adventure tool for those that desire to be unplugged. If you want to have someone keep an eye on you remotely while exercising out at night or in the remote areas, the Garmin does so without requiring anything else.

It is very freeing to be outdoors without a phone, but that functionality comes at quite a price, both in terms of the colossal cost of the watch and the recurring subscription of the inReach plan to provide the service. Fortunately it isn’t reliant on your phone carrier so functions with any make of smartphone and carrier.

This Fenix 8 Pro is a top-tier gadget for someone who hates being burdened by their phone when running, cycling or hiking, but still desires to be locatable and reachable. For everyone else, it is a lot of expense when the excellent Fenix 8 is already available.

Advantages: LTE and orbital messaging, super-bright OLED screen, tracks all activities with premier GPS, integrated torch, voice and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touchscreen.

Drawbacks: extremely costly, LTE and orbital functions require monthly subscription, restricted Garmin Pay financial support, speech capabilities are sluggish, basic wearable functionality versus Apple/Google/Samsung watches.
