China Construction Bank sent me a text message saying that personal text messages cost 3.0 yuan. What happened? What business is it?

This is a short message service for the expenditure or deposit of CCB's savings card account, which is prompted by short messages in 3 yuan every month.

Short message banking refers to the electronic banking business in which customers edit the short message service number in a specific format to the bank, and the bank handles related business for customers according to its instructions, and informs customers of the transaction results in the form of short messages.

Features of SMS banking:

Simple application and low threshold. Individual customers who open an account in a bank can easily enjoy all SMS banking services by binding their mobile phone numbers. Individual customers can register multiple accounts corresponding to multiple mobile phone numbers at one time.

Rich in functions, simple and practical. By signing SMS Bank, customers can send SMS via mobile phone for account inquiry, loan inquiry, payment, micro-loan borrowing, farmer repayment and so on.

All-weather service and timely response.
