Garmin Fenix 8 Pro Review: Built-in LTE and Satellite Connectivity for No-Phone Texting

This latest version of Garmin's flagship Fenix outdoor watch includes a life-saving feature: no-phone communication and emergency alerts using 4G LTE or orbital connections.

This Fenix 8 Pro builds upon the previously outstanding Fenix 8 by incorporating new cellular tech, plus an optional advanced microLED display in a special edition. It is the brand's top device and engineered to be the single tool needed to venture virtually any location and track all your movements.

This positions it as an very expensive option, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED screen – almost twice the price of the standard Fenix 8.

You do receive a lot of features for your investment, with best-in-class workout, activity and adventure tracking. Its complete offline mapping of the world can automatically direct you return to the path if you get lost without a phone, and look excellent on the large, crisp and high-luminance touchscreen.

The Fenix 8 Pro is only available in 47mm or 51mm case dimensions, omitting the more compact 43mm size available in other models, so it is a large watch for bigger wrists. However the 47mm OLED model as tested boasts an additional day of smartwatch battery life despite the display on all the time, lasting a reliable eight to nine days between charges.

No-Phone Messaging, Calls and Real-Time Location

Garmin operates its own inReach LTE (4G) and satellite subscription service instead of relying on a watch plan tied to your phone provider, like other smartwatches. But in contrast to Apple or Google's satellite-capable products, SOS messaging is not included for free.

Rather, subscriptions start at £7.99 or similar a month, which provides unlimited LTE text and voice messaging, calls and LiveTrack position sharing – so your contacts or family can keep an eye on you while engaged in running, biking or comparable activities – plus SOS orbital SOS messaging.

Location updates and texts via satellite are then billed on top, with more expensive plans offering various quotas of satellite use, climbing to a £50 a month all-inclusive plan. The watch includes a 30-day trial period so you can test out the service.

After you have completed setup, you simply venture outside without your phone and the watch will connect to LTE. You cannot use it for streaming music or similar tasks, but you are able to place and receive calls, dispatch texts and generally stay connected with your relatives and companions.

Whenever you text someone, Garmin dispatches 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 message back and forth using typed or spoken communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger application, just a mobile number is sufficient to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is time-consuming. It has a collection of personalizable pre-set replies you can send to speed things up. Voice messages and calls perform OK, though as with most wearables, you’re unlikely going to wish 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 selected contacts every time you begin an activity, so they can follow your live location on a map. It’s great for following 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, although the real location has sometimes lagged when transitioning in and out of good LTE coverage.

All of these capabilities are accessible on other Garmin devices if you carry your phone with you, but in locations where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to send texts, location check-ins and emergency SOS.

A guide displays you how to locate the clear view 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 safety feature, though it is important to note that satellite service is limited to the US continent, most of Canada, and the majority of Europe except for regions of Scandinavia above 65 degrees north.

Environmental Impact

The watch is typically serviceable with options available via the customer service site. The battery is rated to retain at least 90% of its original power after two years of regular charging. The watch lacks 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 additional Garmin inReach service plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

The Fenix 8 Pro takes a fantastic outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus satellite communication, location update and SOS SOS for when you’re without coverage.

Outcome is an even more remarkable adventure tool for those that want to be unplugged. 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 anything else.

It is very freeing to be outdoors without a phone, but that functionality carries quite a cost, both in terms of the substantial price of the watch and the recurring fee of the inReach service to provide the features. At least it is not dependent on your phone carrier so works with any make of smartphone and carrier.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when running, cycling or hiking, but nevertheless wants to be locatable and contactable. For other users, it is a significant expense when the excellent Fenix 8 already exists.

Advantages: LTE and satellite messaging, super-bright OLED display, tracks all activities with best-in-class GPS, integrated flashlight, phone and offline commands, 8+ day endurance, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: extremely expensive, LTE and satellite features need ongoing subscription, limited Garmin Pay financial compatibility, voice capabilities are sluggish, limited smartwatch features compared with Apple/Google/Samsung watches.
