Boku is a simple and exciting way to deposit money to your favorite online casino. All you need is a mobile phone and you'll be able to send money instantly. Why is this method so exciting? You don't need a credit card, debit card, or to hook up a bank account. Any deposit you make to an online casino accepting Boku is added to your monthly mobile phone bill. It's so easy, you don't even need to set up an account. Simply visit your favorite online casino, set up your deposit, and click pay by mobile. You'll be asked for your mobile phone number. As a security measure, before the Boku deposit clears, you'll receive a text asking if you authorize the charge. Respond with the letter Y and you're all set.
