We used Grab on a trip to Vietnam a few months before the Covid shutdown. I took a look at the app today and realized I needed to enter a current credit card. Guess what. It doesn't like any of my multiple entries.
- Doesn't take AMEX
- Visa: tried multiple Chase cards. No joy.
- Visa: tried an Alaska Airlines card (Bank of America). No success
- Mastercard: tried a Flying Blue card. No success
What do I do? What US credit card will it accept?
