I want to change my Indian number to my USA number in Niyo SBM, how do i go about it?

I have my card but cannot set its ATM pin as my Indian number doesn’t work in the US and it needs a OTP which comes on the mobile number. Can you suggest an alternative way to setting my ATM pin?
Also what’s the difference between International ATM’s and other ATM’s? Are there any SBM atm’s in New jersey?
