Yes, same amount, currency, and recipient. Anyway, I have just found out that fees for payments in Euro toward Serbia have been raised in the last week, apologies.
Also, there is a big difference in fees when you select how fast you want the transfer, and this may be the reason for the price difference. There is no way to do this selection in the Bunq app.
Another annoying thing when using Transferwise integration in Bunq is that you cannot save the contact. After selecting the currency, Euro in my case, you must fill in the IBAN, as soon as you do it the app recognized that a SWIFT payment is needed and then starts the Transferwise integration, and you have no option to save the contact; of course you can save the contact in Transferwise, but you still need the IBA at hand to start the integration. Especially for business customers that work internationally, this integration should be better.
