I CAN'T BUY IT!
Hybrid dual SIM? Where did you read that?
On Nokia's spec page it does not even say SD card slot, so either they forgot it they ditched both SD-slot and head phone jack.
If that's true, sirocco is a mistake (going the Apple way ain't never gonna sell on android, aka removing useful features like removable SD for snappy transfers to pc via pci-e SD-card reader or Usb3 (maxed speed) reader).
Lets just hope the file transfer sirocco supports is the snappy version (ie usb3 supports it and internal hardware supports it) or people are gonna experience the (iphone style) night mare of transferring 60Gb movie data in roughly half a day .
Ia have done it at work with my mandatory (horrible) iPhone7+. I will NEVER buy a phone without sd-card after that :)
