When you purchase a prepaid card, we send you card management link by email (which is card issuer's website). You need to visit that page to see card details, transactions etc.
Card issuer restricts access from unsupported countries and as VPNs are not allowed by them. We can actually send you card details directly without any 3rd party link, but you cannot see transaction history in this case. (if you prefer that you can contact live support)
