You likely know the drill by now; usually when a new handset is about to break cover it starts appearing in official certification documents all over the world; they'll pick up certifications for major connectivity protocols, including Bluetooth from the Bluetooth SIG, Wi-Fi from the WFA, and certifications from major national authorities such as China's TENAA and the US FCC.

The Galaxy S9 and Galaxy S9+ have now rocked up in a listing with the latter authority, the US Federal Communications Commission, with the model number SM-G960 for the regular edition, and SM-G965 for the Plus. The listings detail how both phones are to be manufactured in Vietnam, China, and Korea, and will support all major LTE, GSM, UMTS and CDMA bands.

Versions dubbed SM-G960U, SM-G960U1, SM-G960W and SM-G960XU are all mentioned. It's thought the first two are for the US market and the third is for the Canadian market. The fourth is belived to be for promotional and demonstration units. Similarly for the Plus model there are SM-G965U, SM-G965U1, SM-G965W and SM-G965XU variants.

That's about all the info we get from the FCC, but fortunately we do know a bunch of other specs and details thanks to the Samsung Galaxy S9 retail box leaking last week.

The leak confirmed IP68 water and dust resistance, a QHD+ Super AMOLED display, AKG branded and tuned stereo speakers and headphones, and a 12MP primary camera with "Super Speed" Dual Pixel phase detection autofocus and a variable f/1.5/f/2.4 aperture.

With the duo showing up at the FCC there's not going to be long before they are launched - but we knew that anyway with Samsung having already lined up a launch event for MWC 2018 in February!
