Yup Kippo is FREE and always will be! But we also have a premium subscription tier called Kippo Infinity to help enhance your experience even more, like way more.
Kippo is a pretty new app and we're focusing on growing in the NA region first. We understand that gaming is a global community and hope that we can bring Kippo to the world as soon as possible. We don't have a rollout plan for global expansion at this time but we will make sure to keep everyone updated as soon as we have news!
If your carrier is T-Mobile or Sprint, this is likely the issue. These carriers often rate limit or block codes from being sent and Kippo cannot prevent them from doing so. Please contact your carrier customer service and let them know you're not able to receive verification codes.
