I bought nokia lumia 610 4 years ago. till now it is working fine for calling . but ram and external memory is very less. whatsapp is not working fine .i did not get any update for window8.its design is pretty good and battery back up is very nice.Accessories of this phone is not available in the market.camera quality is pretty good but front camera is not available .we can not do video calling.this phone is not good for present time due to unavailability of front camera and memory.
