I have purchased this blackberry passport mobile at the price of 37000 rupees before 1 and half year ago . It has 4.5 inch touch screen plus querty key pad . And has 3 gb of ram which is very good . The features are goods but mostly usefull for corporate world . It is available in white and balck colour . Internal memory is 32 gb and expandable . It is 4g mobile which is very good . But is single sim device . The mobile battery is long lasting and the camera clearity is also very good . The look and stylish design make it attractive and handy.This device are very costly as compared to value for money .But black-berry is one of my favourite company so I have tried and using this cell since 1 and half year. Uptil now no problems occoured and maintainance cost is low. Network is good and plus keypad provides you to type manually whenever required. Sound quality is good .Excellent for multitasking but some andriod app may no work but still I loved it. Good luck.
