Why are NAT service plans unavailable in the NAT Gateway console?

NAT service plans cannot be purchased now. If you did not purchase a NAT service plan for a NAT gateway before 23:59 January 26, 2018, you can only associate Elastic IP Address (EIP) with the NAT gateway to provide public IP addresses for that NAT gateway. For more information about how to associate an EIP with a NAT gateway, see Associate EIPs with a NAT gateway.
