I have heard rumors that blackberry does not support all the applications, and also we must pay for all the apps which are available freely in other phone OS's. How true is that? And I heard that BBM is forced app to use by owners of blackberry.You will be having more options for increasing your budget from 15k to 25k INR and Blackberry should be your best of the available options. Still you will fall short in regard to iPhone 5s/5c.
