30 days notice of cancellation of all Emails on Virgin.net

Am a very proud user of virgin.net emails and have been for many years. Is it still possible to continue with virgin.net emails using a Virgin Media Mobile Sim now being operated on the O2 network? I continue to still show and can log into my Virgin Media account using my virgin.net email address. The Virgin Mobile Sim was moved by Virgin Media to O2 a couple of years ago and continues to show “Virgin Media 02“ as a joined together company. Does this not mean I can continue to have a Virgin Media account and thus continue with my virgin.net email account?
