First, you have to
make sure you only have little GoCredit
(100 GoCredits and below) in your
account but enough airtime on your phone
or data bundle, this means that if you are on
a data bundle then you don't need to worry
about having enough airtime on your
phone. Go to Settings » Change
Style, locate any style you want and
press the save option, It will show
downloading. After downloading the style,
you will get an Error Message that You don't
have enough GoCredit to
Buy the Style. The style will apply or go back
and click on "My Styles" on the Style
Menu. You will see the style there.
