How can I change my credit card details?
You can change credit/debit card details for a recurring payment online, login to your VoIPtalk account and select 'Manage my subscriptions'. If your payment fails owing to wrong credit card details, you will be sent an email with a link that will enable you to renew/change your details. Alternatively you have to make a new payment with your new details. VoIPtalk does not store credit card details.
