Abstract: A method performed by a communication device (101a, 101b, 700) in a network (100) comprising mobile networks (103a, 103b) operated by mobile network operators, MNOs, (105a, 105b) is provided. The method includes signaling (1001) to a first server to discover a second server having information about a public land mobile network identifier and a network service of a MNO. The second server has a first fully qualified domain name, FQDN, pointing to a provider domain. The method further includes receiving (1003) a response including a resolution or a redirection of the FQDN; signaling (1005) to discover the information about the network service; and receiving (1007) a response from the second server including a first identification of the information about the network service of the MNO or a second identification that the network service is not available. Corresponding methods performed by a first server and a second server are also provided.
