Do Gazprombank cards work in Bali?

No, Gazprombank cards, including UnionPay in any currency, do not work in Bali, Indonesia, or anywhere else at the moment due to sanctions. As an alternative, you can open a UnionPay card at Rosselkhozbank. It is free to maintain and issue. Based on our experience, it is best to open such a card in Chinese yuan rather than rubles for use abroad. It is more profitable to pay with it, as there is a commission when withdrawing from an ATM and from the bank's side.
