Vietnam Virtual Card guide
A roundup page of guides on using a Vietnam virtual card for common international services: paying for ChatGPT, paying for Claude, signing up for a US Apple ID, running Facebook ads. The content compares directly with the domestic Napas card, MoMo / ZaloPay, and Visa/Mastercard cards issued in Vietnam, so you can see clearly where each one works and where it is still blocked. Note: ChatGPT.com already supports MoMo for the Go/Plus/Pro plans in Vietnam, while Claude still only accepts cards. A Napas card is not an international card, so many international gateways do not accept domestic BINs. All information on fees, limits and card opening conditions is shown in the App and at help.mp.net; this site does not quote prices and does not promise approval outcomes.
