How does consumer finance send text messages every day?

Consumer finance sends text messages to users every day. If SMS is a collection SMS, then users only need to pay off overdue debts as soon as possible, and then consumer finance will not send collection SMS to users. SMS belongs to advertising SMS. At this time, users can directly ignore this short message, and even users do not need to apply for consumer finance loans in the future. They can directly cancel their consumer finance accounts, and they will receive advertising messages after the account is cancelled.

Users need to process the short messages of consumer finance according to the specific situation, or users don't want to read the short messages, so they can intercept them with software.
