Certification checks are always taken as an indication that an unreleased device is just around the corner, we do tend to see upcoming devices get certified weeks before they're due, which is why it's not surprising to see Samsung's next flagship pop up in these checks. The dual SIM Galaxy S7 edge has now been certified by Taiwan's National Communications Commission, that's the country's version of the FCC, it bears model number SM-G935FD.
It merits mentioning here that dual SIM variants of both the Galaxy S7 and the Galaxy S7 edge, model number SM-G930FD and SM-G935FD, have already passed certification in Indonesia. This goes to show that Samsung will release dual SIM variants of its upcoming flagships but it's not like we didn't already know that this would happen. The certification documents show that the handset features 4G LTE, Wi-Fi, NFC, Bluetooth and wireless charging, all of the features you'd expect it to have. Samsung is going to formally unveil the Galaxy S7 and the Galaxy S7 edge at Mobile World Congress 2016 in Barcelona next month.
