Whatsapp is useful if you have moved country and would like to keep receiving texts from your old friends without putting them out. It is one of those cases where politeness dictates that you can't expect people to keep texting you, even though you would have no issue paying the £10 it would cost per month to send 50 text messages.
That said, catering for us is not an 'insanely hot' business idea and a lot may well be swayed to move to Google Hangouts or Skype quite easily.
