Is there a charge for the SMS reminder service of CCB to bind multiple accounts of the same person?

Was detained twice. Now it is a monthly subscription in 3 yuan, that is, 6 yuan is deducted, and 3 yuan is deducted from each card every month. Each card is an independent SMS banking service, even if it is in your name, it will be charged separately, which means that 3 yuan will be deducted from your two cards every month (if it is a monthly subscription). It will be cheaper if you use the package for SMS banking. The subscription fee is 28 yuan, which is relatively cheaper. O(∩_∩)O
