I want share my experience with sbi. I went to sbi branch in order to activate international services on my debit card of sbi. I asked them what I need to do to activate international services on my debit but unfortunately they had no knowledge about this and said its not possible on debit card. Indeed its not true.
Secondly I asked them to let me know the swift code of the main branch and again they said we know only IFSC code.
Finally I got all these services in my ICICI account.
