I am a frequent user of messaging apps and whatsapp is very popular. I started using whatsapp because all my friends were using it. Initial impression were good but later I started disliking it. The only reason for that is its support for 2g network.
This app just refuses to work on 2g network. It takes a year to connect and lifetime to deliver messages. It was so annoying at time that I cant even explain it in words. My girlfriend complaint too many times that I dont reply her on time where the fact was that whatsapp was refusing to deliver msgs because of the 2g network. Its not relaible at all and whatsapp should work on this because network coverage and speed is still a big issue in India.
