Samsung SGH-I337 (Galaxy S4?) hits the FCC with AT&T 4G LTE bands

The AT&T Galaxy S4 may have been spotted at the FCC as the SGH-I337, a handset that comes with support for AT&T's 4G LTE bands and matches the dimensions of the Galaxy S4.

The Samsung SGH-I337 has hit the FCC, and we could be looking at AT&T’s Galaxy S4 version here, although that’s yet to be confirmed.

The SGH-I337 comes with support for AT&T’s 4G LTE support (band 17), which means it’s going to hit the carrier’s stores sooner or later – AT&T is exclusively using LTE band 17 in the U.S. Moreover, Engadget reports that the dimensions of the SGH-I337 match those of the Galaxy S4.

This isn’t the first time we have spotted this particular model number, SGH-I337, as back in late January we saw the same model pop up in an user agent profile that revealed the device would pack a 1920 x 1080 screen. At the time, we wondered this was the AT&T Galaxy S4.

In the previous weeks, we’ve also seen FCC filings for what looked like the Sprint and Verizon Galaxy S4 versions, but in each case there was some sort of link between the Galaxy S3’s model number and the model number of the devices spotted at the FCC.


Things are not that clear with this SGH-I337 device because the model number isn’t similar to the AT&T Galaxy S3’s model number (SGH-I747).

That said, while it’s hardly likely that AT&T has a Samsung LTE device in the works that we don’t know about, we won’t be able to confirm that the SGH-I337 is indeed AT&T’s Galaxy S4 for a few more weeks.
