There seem to exist different versions of the phone.
I can insert 2 nano SIM cards in the device but how to activate the second one? There is no enter PIN dialog popping up. On YouTube I saw an unboxing video that showed dual SIM support.

Enter download mode by powering down the device and then holding both VOL_DOWN and POWER to power it back up. It will boot to a screen saying hTC download mode
.
The 3rd line of the displayed info will say something like htc_oceuhl PVT S-ON
. uhl
corresponds to the single-SIM variant, dugl
is the international dual-SIM variant, and dtwl
is the Chinese dual-SIM variant.
You can exit the mode by selecting "reboot" in the download mode menu.
