If you are using international credit card, you must check if the deposit can be make a transaction before you change SIM card. I had a terrible experience for making a deposit transaction because I was using Korean debit card and it needed me to authorize myself through SMS. The host led me know the deposit website URL right before I arrive to Paris. There are too many steps until your booking is confirmed(passport image sending, filling out website that doesnt work for guest, filling out another website about my information, and making a deposit transaction online). The host is not a person but a team that manages many other rooms in diffrent places so he or she doesn't answer you quickly. The host didn't reply me after 9pm although my checkin didn't go well. I had to get a hotel at midnight and got a refund for one night on my first day of Europe trip.
