To achieve a proper functionality, the user has to be equipped with a SIM card and a mobile provider that supports the selected protocol. Otherwise, redundant erros messages are written into the log (this, for  example, can happen when IPv4/IPv6 is set but the mobile provider does not support this technology). 464XLAT is a transitional technology in the context of migration of networks from IPv4 to IPv6 and may not be supported by the mobile provider.
• Username – user name as defined by the provider for Internet login (not requested in some networks).

• DNS 2 – backup DNS server IP address (assigned if DNS is not allowed from the mobile network).
