Curve Metal acceptance india

Hello,

Before my trip to india, i ordered a curve metal card to enjoy foreign free conversion.
When using my car here, i notice that a get lot of error transaction with terminal payment provided by pine labs, HDFC, etc…
But online payment works fine.
There is a know problem about using this card in India ?

I was in India a couple of months ago and Curve refused to work for me with an underlying Chase debit card with more than sufficient funds to handle any transactions. I then used the Chase card directly with no problem.
