Virgin Mobile used to allow PayPal as a payment option for topups. Super easy, I’d just access my account from my phone, choose the amount, the payment method, and the payment was sent, and the topup appeared on the phone balance.
It might also be a great way to pay monthly service payments for subscribers. No need to sign up with a CC or debit.
