Garmin Fenix 8 Pro Analysis: Integrated LTE and Satellite Communication for No-Phone Texting

This latest iteration of Garmin's flagship Fenix outdoor timepiece includes a life-saving capability: phone-free messaging and SOS alerts via 4G LTE or satellite links.

The Fenix 8 Pro builds upon the already impressive Fenix 8 by adding new cellular tech, along with an optional advanced microLED screen in a limited edition. This is Garmin's top model and engineered to be the single gadget required to venture almost any location and track every activity.

This positions it as an extremely expensive proposition, starting at £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED version and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED display – almost double the price of the standard Fenix 8.

You do get a lot of functionality for your investment, with best-in-class workout, movement and outdoor monitoring. The full offline maps of the world can automatically guide you return to the path if you lose your way absent a phone, and look excellent on the sizable, sharp and super-bright touchscreen.

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

Phone-Free Texting, Calling and Real-Time Location

The company operates its own inReach LTE (4G) and orbital subscription plan rather than depending on a watch plan linked to your phone provider, as with other smartwatches. However unlike competing satellite-capable devices, emergency communication is not included for no cost.

Instead, subscriptions begin from £7.99 or similar a month, which includes unlimited LTE SMS and voice messaging, calls and LiveTrack location sharing – so your friends or family can keep an eye on you while engaged in running, cycling or comparable pursuits – plus emergency orbital SOS messaging.

Location updates and messages via satellite are then billed on top, with higher-tier subscriptions offering different allowances of orbital usage, increasing to a £50 a month unlimited plan. The watch comes with a 30-day trial period so you can evaluate the service.

After you have got it set up, you simply venture the door without your phone and the watch will link to LTE. You cannot use it for streaming music or similar activities, but you can make and take calls, send texts and overall stay connected with your family and companions.

When you message someone, Garmin dispatches them an SMS from a arbitrary phone number, which they can respond to back to your watch. If they install the Garmin Messenger application, you can then communicate reciprocally using typed or voice communications, and initiate voice calls. Your recipient is not required to have a Garmin account to use the Messenger app, just a mobile number is sufficient to sign up for texts.

Messaging on the watch works fine but typing out texts on the small on-screen keyboard is slow. It includes a collection of personalizable canned responses you can use to expedite communication. Voice messages and calls perform OK, although as with most wearables, you’re unlikely going to want to use it for extended conversations as the quality is not ideal.

LiveTrack is the handiest function. You can configure to automatically transmit a link to selected contacts every time you start an activity, so they can track your real time location on a map. It’s great for following race performance, but it mostly serves as a tool for someone you rely on to know your whereabouts in case something happens. It has generally functioned well, though the real location has occasionally lagged when moving in and out of strong LTE signal.

These capabilities are accessible on other Garmin watches if you bring your phone with you, but in areas where LTE does not reach, the satellite activates on the Fenix 8 Pro to send texts, position check-ins and SOS SOS.

A on-screen assistance shows you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a vital safety feature, though it is essential to remember that satellite service is restricted to the US mainland, the majority of Canada, and the majority of Europe excluding parts of Scandinavia north of 65 degrees latitude.

Sustainability

The watch is typically serviceable with options offered via the support portal. The battery is certified to maintain at least 90% of its initial power after two years of regular charging. The watch lacks any recycled components. Garmin provides recycling 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 optional Garmin inReach service plans cost from £7.99 (€9.99/$7.99/A$13.50).

Verdict

This Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and adds LTE for texting, call functionality and LiveTrack – plus satellite messaging, check-in and emergency SOS for when you’re out of signal.

The result is an increasingly impressive adventure device for those that desire 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 accomplishes this without needing additional gear.

This is quite liberating to be outside without a phone, but that capability carries quite a cost, both in terms of the colossal price of the watch and the monthly fee of the inReach service to provide the features. Fortunately it isn’t dependent on your phone carrier so works with any brand of smartphone and network.

This Fenix 8 Pro is a top-tier gadget for someone who dislikes being weighed down by their phone when running, biking or hiking, but nevertheless desires to be trackable and contactable. For other users, it is a lot of expense when the superb Fenix 8 is already available.

Advantages: LTE and satellite messaging, high-luminance OLED screen, tracks everything with premier GPS, built-in torch, voice and offline voice control, 8+ day battery life, Garmin Pay, complete offline mapping and routes, offline Spotify, 100-metre waterproofing and 40-metre underwater use, buttons and touchscreen.

Drawbacks: extremely costly, LTE and satellite functions need ongoing payment, limited Garmin Pay financial compatibility, speech capabilities are slow, limited wearable features versus Apple/Google/Samsung watches.
