I've been looking at a VF Sim only deal and it states "Calls and texts to standard UK mobiles and landlines (01, 02, 03) within the UK. Also applies to local calls and texts to standard mobiles and landlines in any of the 50 destinations of our Pay as you go Europe Zone [PDF: 677KB] plus calls and texts to standard UK mobiles and landlines from those destinations" so yes I agree only calls made to Turkish mobiles whilst in turkey included.
