Banky team Reviewed editorial answerHaving a limit available does not guarantee that every international transaction will be accepted.
Rejection may be due to a different international limit than the local one, a restricted merchant type, an inactive travel setting, a security concern, currency or network restrictions, or if the merchant attempted to reserve a larger amount via pre-authorization.
Instead of repeating the transaction multiple times, check the reason for the rejection with your bank, and double-check the International Usage and remaining limit.
