In my part of the world, Cyprus, my mobile carrier (CYTA) claims that Blackberry service is not available for the new Z10/Q10 phones.

Is this the case, or are they finding excuses for not upgrading their own systems?

BB10 devices do not use BIS.

The regular data plan like you'd use with an iPhone or Android phone is all you need with BB10.
