Garmin is quietly certifying another satellite-connected watch. A new FCC filing for model A05170, granted August 5, describes a wrist-worn device with both LTE and direct satellite radios. No name, no photos, but the public radio documents say a lot about where Garmin's outdoor lineup is headed.
What the Filing Reveals
The device carries FCC ID IPH-05170 and is officially just a "portable digital transceiver." But the SAR evaluation report is explicit that this is a wrist-worn device with no other intended use conditions. Garmin tested it with three straps: silicone, heathered black nylon, and vented titanium.
That last one is the tell. Vented titanium straps belong on premium outdoor and multisport watches, not budget fitness bands.
The radio package is the headline:
- LTE-M (Cat-M1) on North American bands 2, 4, and 12, and per the filing it supports voice transmissions
- NB-NTN satellite on bands n23 and n255, limited to data
- The standard wearable stack: 2.4GHz Wi-Fi, Bluetooth, ANT+, and NFC
In plain terms: phone-free calling when you have cell coverage, satellite communication when you don't. That's the same playbook Garmin introduced with the Fenix 8 Pro, and it's now showing up in something newer.
There's no GNSS transmitter listed, but don't read into that. GPS receivers don't transmit, so they wouldn't appear in the transmitter side of an FCC filing anyway.
Fenix 9 Pro inReach or Enduro 4?
The filing never names the watch, so this is informed guessing. Two candidates stand out.
The stronger fit is the Fenix 9 Pro inReach. Recent reporting suggests Garmin is preparing three Fenix 9 models at once, with LTE and satellite sitting on the top inReach tier rather than every SKU. A fresh wrist device with exactly that connectivity mix slots neatly into that lane. The Garmin Rumors team points out that cellular on only one tier also explains why we haven't seen LTE chatter around the standard Fenix 9.
The dark horse is the Enduro 4. A Garmin Connect teardown found an Enduro 4 entry with internal ID 5179, and the similarity to model number A05170 is fun to stare at. But Garmin's FCC model numbers and app identifiers don't necessarily match, and nothing in the app ties Enduro 4 to LTE or satellite hardware. If it is the Enduro 4, it would be the first Enduro with phone-free connectivity.
Either way, we covered the Enduro's own FCC filing earlier, and that one had no satellite radio in sight.
Is This "Real" inReach?
That's the question Garmin's own community is arguing about, and it matters. Traditional inReach devices use Iridium, which gives true global coverage. The NB-NTN bands in this filing point to the newer satellite LTE approach instead, the same one the Fenix 8 Pro uses. It works in most places people actually hike and climb, but it isn't Iridium-grade global.
If Garmin pulled off Iridium in a watch, the antenna alone would dominate the case. As one commenter on Garmin Rumors put it, the expectation of that happening is "exceptionally low."
What's Still Hidden
External photos, internal photos, and the owner's manual stay confidential until February 1, 2027. Garmin can announce before then, release documents early, or extend, so that date isn't a launch deadline.
One detail is encouraging: Garmin states the tested unit has the physical, mechanical, and thermal characteristics expected from production hardware. Development looks well advanced, even if manufacturing hasn't officially started.
Display, case size, sensors, battery life, price: all still unknown.
Bottom Line
This isn't a rumor mill invention. Garmin has a wrist-worn LTE and satellite device in active certification right now, and the titanium strap testing points squarely at the premium outdoor line. Whether it lands as the Fenix 9 Pro inReach or an Enduro 4 surprise, the direction is clear: Garmin is pushing phone-free connectivity down its flagship lineup, one FCC filing at a time.
We'll keep watching for the product name to surface.
