Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Connectivity for No-Phone Messaging

This most recent version of Garmin's top-tier Fenix adventure timepiece introduces a potentially lifesaving capability: no-phone communication and SOS messaging via 4G LTE or satellite links.

This Fenix 8 Pro builds upon the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an available advanced microLED screen in a limited edition. This is Garmin's top device and engineered to be the single tool required to explore almost anywhere and track all your movements.

That positions it as an extremely pricey option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly twice the price of the regular Fenix 8.

You do get a significant functionality for your money, with best-in-class workout, movement and outdoor tracking. The complete offline maps of the globe can seamlessly direct you return to the trail if you lose your way without a phone, and look excellent on the large, crisp and super-bright touchscreen.

The Fenix 8 Pro is exclusively offered in 47mm or 51mm case sizes, omitting the smaller 43mm size available in other devices, so it is a large watch for larger wrists. However the 47mm OLED model as tested does have an extra day of smartwatch battery life even with the display always active, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite subscription plan instead of depending on a watch plan tied to your phone provider, as with other wearables. But unlike Apple or Google's satellite-enabled products, SOS messaging is not provided for free.

Rather, plans start at £7.99 or equivalent a month, which includes limitless LTE text and audio messaging, calls and LiveTrack position sharing – so your contacts or loved ones can monitor you while engaged in jogging, cycling or comparable activities – plus SOS satellite SOS messaging.

Check-ins and messages via orbital are then billed on top, with more expensive plans offering various quotas of satellite usage, climbing to a £50 a month unlimited plan. The watch includes a 30-day trial period so you can test out the service.

After you have got it set up, you simply head out the door minus your phone and the watch will link to LTE. You cannot use it for streaming music or comparable tasks, but you are able to place and receive calls, send texts and generally keep in touch with your family and companions.

When you message someone, Garmin sends them an SMS from a arbitrary number, which they can reply to directly to your watch. If they install the Garmin Messenger application, you can then message reciprocally using typed or voice messages, and make voice calls. Your recipient does not need a Garmin profile to use the Messenger application, only a phone number is enough to register for texts.

Texting on the watch works fine but typing out texts on the tiny on-screen keyboard is slow. It includes a set of personalizable canned replies you can send to speed things up. Voice recordings and calls perform acceptably, though as with the majority of wearables, you’re unlikely going to want to use it for lengthy discussions as the quality is not ideal.

LiveTrack is the most useful function. You can configure to on its own transmit a link to selected contacts whenever you begin an exercise, so they can follow your live position on a map. It’s excellent for monitoring competition performance, but it primarily acts as a tool for someone you trust to be aware of your location in case something happens. It has generally functioned well, though the actual position has occasionally lagged when transitioning in and out of good LTE signal.

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

A on-screen assistance displays you how to find the line of sight to the satellite, which then transmits and gets messages within about 10 to 30 seconds. It was unexpectedly easy to use and could be a crucial lifeline, however it is essential to remember that orbital coverage is restricted to the US continent, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees north.

Sustainability

The watch is typically serviceable with services offered via the support portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch lacks any reused materials. Garmin offers disposal programs on recent purchases.

Cost

This Fenix 8 Pro costs from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach service plans begin from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and adds LTE for messaging, call functionality and LiveTrack – along with satellite communication, location update and SOS SOS for when you’re without signal.

Outcome is an even more impressive outdoor tool for those that desire to be phone-free. If you want to have someone keep an eye on you from afar while running out at night or in the remote areas, the Garmin does so without needing additional gear.

It is quite freeing to be outside without a phone, but that functionality carries quite a cost, both in terms of the substantial price of the watch and the recurring subscription of the inReach plan to enable the service. Fortunately it is not reliant on your phone provider so functions with all brand of smartphone and network.

This Fenix 8 Pro is a top-tier device for someone who dislikes being burdened by their phone when running, biking or trekking, but nevertheless desires to be locatable and contactable. For everyone else, it is a significant money when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED screen, monitors everything with premier GPS, integrated flashlight, phone and standalone commands, 8+ day endurance, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Drawbacks: extremely costly, LTE and orbital features require ongoing subscription, restricted Garmin Pay bank compatibility, voice capabilities are sluggish, limited smartwatch features versus competing watches.
