I do understand you need an ultra cheap phone, but a phone below 2000 is simply not worth it. There are, however, simple android phones for around 2000-4000. Micromax Bolt Intex Aqua R2 Karbonn A100 Karbonn S15
For 3800, this phone has brilliant value for money: Intex Aqua N7
I have recently purchased this phone, but the whatsapp is not working. It gives me verification error everytime i try to activate whatsapp. Any suggestions?
