In an effort to promote Hello Bank's mobile platform, the company launched a 'Mobile Concerto' campaign where a symphony is played using only mobile devices. The digital instruments are coordinated to pump out a symphony in full force. At the end of the performance, the text "it's amazing what you can do with a mobile, now you can have your bank in your mobile" appears.

With an unsuspecting audience, Hello Bank switched out traditional instruments for constructs made up of only smartphones and tablets. From violins to flutes, each instrument was reconstructed back into its original shape with touchscreen devices. Each violin was made up of a tablet and three phones while flutes were made of two phones. All of these devices were secured on a black plastic mount.
