Just install the walkietooth on your symbian phone( ver 7 or 8,8.1) and enjoy free talks with other symbian phones in your surroundings by making use of bluetooth technology in your phone.

We dont have to pay anything to talk to any mobile within the bluetooth range.

I just added some mp3 which would help you to know some basics in spanish like how to greet and welcome others.
