Boku is simple, easy to use and incredibly fast. On top of that, the payment option can be used on multiple devices and in over 50 different countries, making it a great payment method. However, it depends entirely on how you’re using it (Contract or pay-as-you-go) and whether you’re connected to a mobile carrier that accepts it. However, it’s important to keep track of your deposits to ensure you don’t overspend, and the fact that so few casinos accept Boku can be a little disappointing. But still, the method is great to use for gambling.
