Vergin Mobility! How is their prepaid Service?

I am planing to sign up with Virgin for prepaid for my daughter. It sounds reasonable to me and top ups last for 120 days,
can some one advise me on this please.

Why doesn't anyone advise me on Vergin mobile prepaid.
Pl guys

You can’t beat Virgin’s pay-as-you-go prices! $.40 per day and $.10 per minute airtime....or $.25 per minute airtime and $.15 per minute airtime after 4 minutes each day. Free call display, text messaging, and message centre. And to save charges, you can check your voice messages on a landline for free! What a deal for the occasional user.
