A method, system, and computer usable program product for dynamic access to radio networks are provided in the illustrative embodiments. A new radio network having a characteristic more suitable than a corresponding characteristic of a present radio network is detected. A request for access to the new radio network is sent, the request including a token, which includes structured information about a user, a device, a home network, or a billing service. Access to the new radio network is received. Switching is performed from the present radio network to the new radio network for wireless communication. The request for access to a radio network is received such that the requester is not known to a provider of the radio network. The requester is verified using a billing service provider or a home network provider identified in a token in the request. Upon verification, access is granted to the radio network.
