With Callertunes, you can play your favourite song for all your callers instead of the normal tring tring. You can try wacky sounds to pure instrumental and more. And if that's not enough, record a message in your own voice and set it as your Callertune. This can be done when you are busy and unable to take a call. This is what the new vodafone ad says. I feel it has succeeded in conveying the message. All the messages are like songs which are catchy and this ad will surely stay for sometime in one's mind. Other than this, vodafone ad has punchline like "Happy to Help" for the Girl and Doggy ad. Ofcourse there are lots of zoo zoo ads.
