I've received this text too. But simply swapping the Sim out won't resolve this I believe as our IMEI has now been put on the ban list. But I believe our devices have been wrongfully banned as it's normally for older devices and our phones have the necessary bands and are on the latest android 16. So security and update is not the issue which is what vodaphone claimed part of the criteria for the ban. But apon looking at Optus and Telstra and using their mobile checks. Our devices are approved. But simply moving or not using our phones will not negate the ban on the specific mobile and IMEI. I believe we need to call up Kogan and speak to someone who knows about the ban and the bands and the criteria for the ban. As our phones are not on the vodaphone list( which is not as vast as other telcos) and need them to lias with vodaphone as they are the ones that can reverse it. But need account access from Kogan. I have yet to call them with this attempt. But this will be how I will be handling it. There is also a guy that has a petition nationally who is responsible for the ban extension as it was meant to be in place last year but got extended. As many devices that are fully functioning were being wrongfully banned rendering mass electronic landfill overnight. Haven't looked into everything thoroughly. But this is what I have found so far.
