It is not necessary to activate a credit card once you have applied for it, but the credit card cannot be used normally without going through the activation procedures. Of course, it will not incur any fees. The cardholder can only use the credit card after going through the credit card activation procedures. For normal card consumption, if the cardholder does not go to the bank branch counter to handle activation procedures within the validity period of the credit card, the credit card will automatically become invalid. If the cardholder wants to use the credit card, he can only apply again.
