No problem at all...it automatically added my main card when I restored via iCloud out of the box, and then added my other cards to it without an issue. Interestingly, I have a Chase business debit card I load on it, and my 6 Plus could never properly read the numbers fully on the front when adding it...the colors blend a bit and it couldn't recognize them. This phone, however, had zero problems seeing all of the numbers on the first try.
