If you are currently with another service provider (ISP) you will need to obtain a MAC CODE (Migration Authorisation Code) from your existing ISP. Your current service will continue to work with existing ISP until the migration date.You will be sent a new username, password and modem or router before the migration date. There will be approximately 30 minutes downtime whilst reconfiguration takes place. Once the migration is complete your product will automatically be upgraded to the 8MB service with no additional down time. Please note a MAC code is only valid for 30 days.Please contact your current ISP to cancel this service.
