A method of managing subscription credentials in a wireless communication device wherein the communication device is adapted to hold pre-configured temporary access credentials for gaining temporary network access and for obtaining new long-term subscription credentials and wherein the temporary access credentials comprise a preliminary international mobile subscriber identifier permanently held in the wireless communication device, the method being adapted for: - obtaining long-term subscription credentials; reverting (102, 120) from the long-term subscription credentials to the pre-configured temporary access credentials held in the wireless communication device substituting the temporary access credentials pre-configured in the wireless communication device in place of the long-term subscription credentials while retaining the temporary access credentials at the wireless communication device for future reversion; determining whether new long-term subscription credentials are needed while having temporary network access via the temporary access credentials; and for, if new long-term subscription credentials are needed, obtaining new long-term subscription credentials for the wireless communication device via the temporary network access; characterized in that the long-term subscription credentials are associated with a preferred access network; the method comprising the steps - detecting a failure to gain network access using the current long-term subscription credentials held in the wireless communication device by making one or more initial access attempts through the preferred access network using the current long-term subscription credentials, and, - if the initial one or more access attempts are unsuccessful, making one or more subsequent access attempts through one or more non-preferred access networks (116, 118) available to the wireless communication device, also using the current long-term subscription credentials; - if still not successful (116, 118, 104), - reverting (102, 120) from the current long-term subscription credentials to the temporary access credentials held in the wireless communication device responsive to detecting said failure; - scanning for access, and upon access to an access network; - obtaining new long-term subscription credentials. - obtaining long-term subscription credentials; - detecting a failure to gain network access using the current long-term subscription credentials held in the wireless communication device by making one or more initial access attempts through the preferred access network using the current long-term subscription credentials, and, - if the initial one or more access attempts are unsuccessful, making one or more subsequent access attempts through one or more non-preferred access networks (116, 118) available to the wireless communication device, also using the current long-term subscription credentials; - if still not successful (116, 118, 104), - reverting (102, 120) from the current long-term subscription credentials to the temporary access credentials held in the wireless communication device responsive to detecting said failure; - scanning for access, and upon access to an access network; - obtaining new long-term subscription credentials.
