Is it possible to get a Visa card from Monzo? I have come across places that only accept Visa, not Mastercard.
Nope only MasterCard.
Do you mean while abroad you encounter these places?
You can check out Revolut as they offer visa and MasterCards.
The latest was applying for a Saudi eVisa- I’m planning to visit relatives over there.
Shockingly the internet forums suggest that for Saudi evisa Amex works best.
