I saw this series of advertisements from Imsy. Its a company from India I had not heard of before.
However, the question ‘Still spending on SMS?’ should be a cause of concern for Operators.
This is not whatsapp (which I use and many here in Europe use as well) – but my point is this – anyone can create such a service in an era of Smartphones! The Operators cannot really stop it. This type of service will be the norm soon – and Operators cannot ban them any more.
They will of-course eat into SMS!
