A few days ago we reported that the Xperia XZ Premium Dual would support the ability to use two SIM cards and a microSD memory card at the same time. This was following on from a tweet by Sony Xperia France, which has since been deleted.
Well, now we know why it was deleted. The official user manual for the Xperia XZ Premium confirms that the dual SIM model will feature a hybrid SIM tray after all. Therefore, you can only use one SIM card, if you plan to use a SD card at the same time. The only Xperia models that do not feature a hybrid SIM tray in their dual SIM variants are the Xperia XA1 and XA1 Ultra.
