I tried to use this virtual card on my Samsungpay but SamsungPay does not allow me to add it. GPay also not recognized this card.

They have 4 types of cards with different BINs (I think it's the Bank Identification Number). Not all types of their cards can be used in some of the services they support, but for now they're not as global as we think. Samsungpsy and GPay aren't yet supported for all card types:
