Earlier today we got an early look at the design of the Galaxy S21, and now we're learning more about its internals.

The Samsung Galaxy S21 has passed through the FCC ahead of its expected announcement next month (via Droid-Life). The S21 carries the model number SM-G991U and there are a couple of notable details about the next Galaxy S flagship confirmed by the FCC's filing.

First up is that the Samsung Galaxy S21 will support a wide variety of cellular bands. That includes 4G LTE and 5G for the major U.S. carriers, and even older tech like 2G and CDMA/EVDO. So just like other recent Galaxy flagships, the S21 should work on most any carrier you want to use it on.

Support for Bluetooth 5.0 and 802.11a/b/g/n/ac/ax is included, too, as well as NFC and wireless charging.

Another interesting tidbit is that it appears that this FCC filing has confirmed that the Galaxy S21 will be powered by Qualcomm's Snapdragon 888 processor, at least in the U.S. "This equipment contains the Qualcomm SM8350 modem supporting 2G/3G/4G WWAN and Sub6/mmW 5G NR bands," the FCC says.

Over on Qualcomm's website, it's got a product brief for the Snapdragon 888 that confirms the chip's part number as SM8350. And we know that one of the features of the Snapdragon 888 is that includes a 5G modem built-in.

For many generations now, Samsung has included an Exynos processor in its Galaxy S flagship for most of the world but opted for high-end Snapdragon chip in the U.S. Some folks may have thought that the Galaxy S21 would buck that trend and skip the Snapdragon 888 after Samsung was absent from a list of 14 companies that'd committed to supporting the SD888, but now it looks like we've got confirmation that Qualcomm's new flagship chip will indeed power the Galaxy S21.
