You must have a Google Wallet account associated with your Google Account to purchase items from the Google Play Store app.
To create a Google Wallet account, do one of the following:

– or –
- The first time you use your phone to buy an item from Google Play, you’re prompted to enter your billing information to set up a Google Wallet account.
Warning: When you’ve used Google Wallet once to purchase an application from the Google Play Store app, the phone remembers your password, so you don’t need to enter it the next time. For this reason, you should secure your phone to prevent others from using it without your permission. (For more information, see Screen Lock Settings.)
