What is the reason for sending SMS reminders to credit cards?

Generally, mass senders send them in batches.

Short messages are still sent in a targeted way. Don't worry too much when you receive such a short message, and the role of reminder is more obvious.

Generally, this happens when the user automatically deducts fees from the bank credit card, and this account is directly deducted from the card. Simply put, ABC's batch payment is to participate in investment in wealth management products. When several items are returned at the same time, users will receive information.
