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

This most recent version of Garmin's flagship Fenix adventure watch brings a life-saving feature: no-phone communication and SOS alerts via 4G LTE or satellite connections.

The Fenix 8 Pro upgrades the already outstanding Fenix 8 by incorporating cutting-edge cellular technology, plus an optional advanced microLED display in a limited edition. This is the brand's top model and designed to be the only gadget needed to explore virtually anywhere and track every activity.

That positions it as an extremely pricey option, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and reaching a substantial £1,730 (€2,000/$2,000/A$3,399) for the 51mm edition with microLED display – nearly double the cost of the regular Fenix 8.

You do receive a significant features for your money, with best-in-class workout, activity and adventure monitoring. Its complete offline mapping of the world can seamlessly guide you back to the path if you lose your way without a phone, and look excellent on the large, sharp and high-luminance display.

This Fenix 8 Pro is only available in 47mm or 51mm case sizes, not the more compact 43mm size found in other models, so it is a large watch for bigger wrists. But the 47mm OLED model as tested does have an additional day of smartwatch battery life even with the screen on all the time, lasting a solid eight to nine days between charging.

No-Phone Messaging, Calling and Live Tracking

Garmin uses its proprietary inReach LTE (4G) and orbital subscription service instead of depending on a watch plan tied to your phone provider, like other smartwatches. But in contrast to competing satellite-capable devices, SOS communication is not provided for free.

Instead, subscriptions start at £7.99 or similar a month, which includes limitless LTE SMS and voice messaging, calls and LiveTrack location tracking – so your contacts or loved ones can monitor you while out running, biking or similar activities – along with SOS orbital SOS messaging.

Check-ins and texts via orbital are then charged additionally, with more expensive plans including different quotas of satellite use, increasing to a £50 a month unlimited plan. The watch comes with a 30-day free trial so you can evaluate the service.

After you have got it set up, you simply venture outside without your phone and the watch will link to LTE. You can not use it for streaming music or comparable tasks, but you can place and receive calls, dispatch texts and overall keep in touch with your relatives and companions.

When you message someone, Garmin sends them an SMS from a random number, which they can reply to back to your watch. If they download the Garmin Messenger app, you can then message back and forth using text or spoken messages, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger app, just a phone number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It has a set of personalizable pre-set replies you can send to expedite communication. Spoken recordings and calls perform acceptably, though as with most smartwatches, you’re not going to want to use it for extended conversations as the quality is less than fantastic.

LiveTrack is the most useful feature. You can configure to on its own transmit a link to chosen contacts every time you start an activity, so they can track your live location on a map. It’s excellent for following race progress, but it mostly acts as a tool for someone you rely on to know your whereabouts in case an incident occurs. It has typically functioned well, although the actual location has sometimes lagged when transitioning in and out of strong LTE signal.

All of these features are available on other Garmin watches if you bring your phone with you, but in areas where LTE lacks coverage, the satellite activates on the Fenix 8 Pro to transmit texts, position check-ins and emergency SOS.

A guide shows you how to locate the line of sight 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 orbital service is restricted to the US mainland, the majority of Canada, and most of Europe except for regions of Scandinavia north of 65 degrees latitude.

Environmental Impact

The watch is generally serviceable with services available through the customer service site. The battery is certified to maintain at least 90% of its initial capacity after two years of regular charging. The watch does not contain any reused components. Garmin offers disposal programs on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional 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 standard Fenix 8 and adds LTE for messaging, calls and LiveTrack – along with satellite messaging, check-in and emergency SOS for when you’re out of coverage.

Outcome is an increasingly impressive adventure tool for those that desire to be phone-free. If you wish to have someone monitor you from afar while running out at night or in the remote areas, the Garmin accomplishes this without requiring additional gear.

It is quite liberating to be outdoors without a phone, but that functionality comes at a significant cost, both in terms of the colossal price of the watch and the recurring subscription of the inReach plan to provide the service. At least it isn’t dependent on your phone carrier so works with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who hates being burdened by their phone when running, biking or hiking, but still desires to be trackable and reachable. For everyone else, it is a significant money when the excellent Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED display, tracks all activities with premier GPS, built-in flashlight, phone and offline commands, 8+ day battery life, Garmin Pay, full offline mapping and navigation, offline Spotify, 100-metre water resistance and 40-metre underwater use, physical controls and touchscreen.

Cons: extremely expensive, LTE and satellite functions require monthly payment, limited Garmin Pay bank compatibility, voice features are slow, limited wearable functionality versus Apple/Google/Samsung watches.
