It is waste phone of Nokia .I have used it. It's not a good mobile for calling.
The caling function in this mobileis very bad and it's not a fake review, because I have done personal trials. In this mobile a single sim card and memory card slot are given.It has a 5 MP back camera which is quite useful.
Nokia E5 is not useful for nowadays. But in the olden time it was very precise and prevalent. It has a keypad which is not useful because it's keypad has very small small buttons who do not appear. and it size is also not much good to put in pocket or hand. It has a 1200mAH battery, which is removal .
but in the real it's battery backup is still not good .it has some featured like Bluetooth, wi-fi, GSM.
It's Bluetooth connectivity is not good. I think this mobile is not for present day.
