What specific information about my recurring topup profile can I modify?
You can change the recurring topup amount. For profiles created using Paypal, the recurring topup amount can only be increased by 20% in a fixed 180-day interval after the profile is created and changes are not allowed within 3 days of the next scheduled billing date. For profiles created using a credit/debit card, you can also update your credit/debit card expiration date and billing address. When you update your credit/debit card info, you must enter all of the required fields, not just those that are changing.
