Badoo is a freemium service, where the basic service is free for everyone but users have an option to pay for premium features.

Do you have to pay on Badoo?

Since Badoo dating is a free service, messaging others is possible, even without paying for premium services. The only thing you need to start a conversation is to upload a photo of yourself. Once you have a picture, you can network with other members or ask them out on dates.
