I have not encountered such problems before. I have been traveling for about five years in different cities and countries. I have a regular bank card-a visa. Yes, there were failures during the move, long transfers. But when I arrived in Turkey, my card did not work. The bank told me that they needed to be warned about purchases and using the card in Turkey. Why is that? I had to pay for the receipts of my accommodation in Turkey through the website Paystub Generator | The Best Checkstub Maker Online in USA. I couldn't do it. It's good that the hotel residents helped me. I paid them the debt in cash. On my next trip to Turkey, I notified the bank in advance.
