Is the UNI NX wave CC good?

I got this mainly for my international trip to Bali.

But my main concern is since it’s Mastercard, will it work well in Bali?

I know VISA has a much higher acceptance rate.

Also I just got the card today and on the back side the last 2 digits of the CVV are faded, can barely make out the numbers.

Should I return the card. Have not activated it yet
