Hi @withamimp76,
Thank you for coming back to us. This process is the same with all service providers and in order for us to be table to have the number available to port over to Virgin Media, your previous providers would need to send that information over to us internally.
Is your old landline number still active for us to be able to port your number over to us? This can only be done if your landline number is active.
Keep us updated so we can help further.
Thank you.
