According to the Sony description the Xperia 1 ii can be equipped with one SIM and one SD or two SIM this is clearly shown in the manual ( Xperia 1 II XQ-AT51/XQ-AT52) which means two different models must exist. Searching in internet there are sellers which have the two SIM version for selling. After getting in contact with Sony they confirm that the two SIM version is not available in Europe. Therefore one has to be careful to order a two SIM card version and get a single SIM version as it happen with me since I believed the provider which insist that it will be a two SIM card which was of course wrong.
