What is the use of short message service of CITIC Bank? People in the bank keep asking me to open it.

If the landlord is interested in SMS service, I can simply tell the landlord about the SMS service of CITIC Bank credit card. As long as the landlord opens this service, the bank's credit card approval notice, transaction notice, bill notice, account prompt, information change notice, fund arrival notice, product information service, etc. It can be sent to the mobile phone number reserved by the landlord at that time, especially the bill notice, which directly avoids the overdue situation caused by the landlord forgetting the repayment date. That is me.
