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.

  • Use apps from play store like *device info / my device , etc*/ look at your purchase invoice which should have the model number to find out. Please do that first and ask.

  • In this video for example it says SIM2 on the adapter.

  • @MichaelS. Can you see two network icons after inserting two sims on sim tray? I think you were doubted about 4G/3G settings on both sim.

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.

  • Any chance to find out in store before buying the next one?

  • Ask any store receptionist? You have the rights to know this info as a customer. What I offered is more of a surefire, after-purchase method and would help better in situations like buying a used device.
