How do I pay to uni assist (Masters in Germany) I have a SBI debit card?
I doubt if you would be able to make a payment with SBI Card. Perhaps you will be able to, only and only if you card falls into the category where you can make international payments.
Typically this has to be made payment via international credit cards. Its easier, else you can also approach third party transfer vendors like Centrum, Thomascook or any nationalized bank.
Tip - Compare the price at each place and then take a call.
