Embodiments herein relate to a method performed by a second network node for enabling communication for a wireless device in a communication network, which communication network comprises a first network and a second network. The second network node is associated with the second network and the first network is a home network of the wireless device. The first network comprises partitioned sets of functionalities wherein a first set of functionalities belongs to a first network slice supporting the wireless device, and which first set of functionalities is separated from another set of functionalities out of a total set of functionalities in the first network. The second network node, when the wireless device is roaming from the first network to the second network, initiates a connection establishment to a first network node associated with the first network. The second network node retrieves a policy indication from the first network node, which policy indication indicates a first network slice and roaming policy for the wireless device in the first network. The second network node further triggers a selection of a second network slice and roaming policy for the wireless device in the second network, which selection is based on the retrieved policy indication and internal data related to the second network.
