Few threads indicated that there is no dual SIM support, but then I saw a post where (unless it was April's fools day) someone said sim cards go back to back instead of side by side and it is a dual sim phone. Since I travel often to Europe, I need dual SIM feature. Could someone definitely answer this question, please? I bought mine directly from OnePlus U.S. website and it is already back in the box because of this issue, waiting for a RMA label to arrive and I don't want to open it again. I did not see second IMEI number is settings, but maybe it is hidden somewhere and can be activated by a factory code?
