Garmin Fenix 8 Pro Review: Built-in LTE and Orbital Communication for No-Phone Texting

This latest model of the top-tier Fenix outdoor watch brings a life-saving feature: no-phone messaging and emergency messaging using 4G LTE or orbital links.

The Fenix 8 Pro enhances the already impressive Fenix 8 by adding new cellular tech, plus an optional state-of-the-art microLED screen in a special edition. This is Garmin's premier model and engineered to be the only tool required to venture almost any location and track all your movements.

That positions it as an extremely expensive option, starting at £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 display – nearly twice the price of the standard Fenix 8.

Users get a lot of features for your investment, with industry-leading fitness, movement and outdoor monitoring. Its full offline mapping of the globe can seamlessly guide you back to the path if you get lost without a phone, and look great on the sizable, crisp and super-bright touchscreen.

The Fenix 8 Pro is exclusively available in 47mm or 51mm case dimensions, not the more compact 43mm size found in other models, so it is a big watch for bigger wrists. But the 47mm OLED version as reviewed boasts an additional day of smartwatch battery life despite the screen on all the time, 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 service service instead of depending on a watch plan linked to your mobile carrier, like other wearables. However in contrast to competing satellite-capable devices, emergency messaging is not provided for free.

Instead, subscriptions begin from £7.99 or similar a month, which provides unlimited LTE SMS and voice messages, call functionality and LiveTrack location sharing – so your contacts or family can keep an eye on you while engaged in jogging, cycling or comparable pursuits – plus emergency satellite SOS alerts.

Check-ins and messages over satellite are then billed on top, with higher-tier plans offering various allowances of satellite usage, climbing to a £50 a month unlimited subscription. The watch includes a 30-day trial period so you can test out the functionality.

After you have got it set up, you simply head out outside minus your phone and the watch will connect to LTE. You can not use it for streaming music or comparable activities, but you can place and receive calls, dispatch texts and overall stay connected with your relatives and companions.

Whenever you message someone, Garmin dispatches 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 communicate back and forth via text or voice messages, and make voice calls. Your contact does not need a Garmin account to use the Messenger application, only a phone number is sufficient to register for texts.

Messaging on the watch functions adequately but typing out texts on the small on-screen keyboard is slow. It includes a collection of customisable pre-set replies you can send to expedite communication. Voice messages and calls perform OK, though as with the majority of smartwatches, you’re not going to want to use it for extended conversations as the audio clarity is not fantastic.

LiveTrack is the most useful feature. You can configure to on its own transmit a URL to chosen contacts every time you begin an activity, so they can track your live location on a map. It’s great for following race performance, but it primarily acts as a tool for someone you rely on to know your location in case something happens. It has generally worked well, although the real location has sometimes been delayed when moving in and out of strong LTE coverage.

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

A on-screen assistance displays you how to locate the line of sight 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 safety feature, though it is important to remember that orbital service is limited to the US mainland, most of Canada, and the majority of Europe excluding parts of Scandinavia above 65 degrees north.

Sustainability

The watch is generally serviceable with options available through the customer service portal. The battery is certified to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin offers disposal schemes on new 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

This Fenix 8 Pro builds on a fantastic adventure watch in the standard Fenix 8 and incorporates LTE for texting, calls and LiveTrack – along with orbital messaging, location update and emergency SOS for when you’re out of coverage.

Outcome is an even more remarkable adventure device for those that want to be unplugged. If you wish to have someone keep an eye on you from afar while exercising out at night or in the remote areas, the Garmin does so without requiring additional gear.

This is very freeing to be outdoors without a phone, but that capability carries quite a price, both in terms of the substantial price of the watch and the recurring fee of the inReach service to provide the service. At least it isn’t reliant on your phone carrier so works with all brand of smartphone and network.

The Fenix 8 Pro is a top-tier device for someone who hates being weighed down by their phone when jogging, biking or hiking, but still desires to be locatable and contactable. For everyone else, it is a lot of money when the superb Fenix 8 already exists.

Pros: LTE and satellite communication, super-bright OLED screen, monitors everything with premier GPS, built-in flashlight, phone and offline voice control, 8+ day battery life, Garmin Pay, complete offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, physical controls and touch.

Cons: extremely expensive, LTE and satellite features need ongoing payment, limited Garmin Pay bank support, voice capabilities are slow, basic wearable features versus Apple/Google/Samsung watches.
