Hi there
You should have deregistered your SureSignal online through My Vodafone before leaving. Once your number has been ported away, you will no longer have access to My Vodafone, so you won't be able to deregister it yourself. Don't worry though, as this is something that the eForum Team can assist you with. Please be patient and they will be along as soon as they can to drop you a Private Message.
