Why does the bank card open WeChat payment and lock the SMS service?

1, there is no direct connection between bank card SMS service and WeChat payment, so there is no connection between opening WeChat payment and locking SMS service;

2. The SMS service of some bank cards is not monthly, but charged by the article. Therefore, if there is a prompt for each transaction, it may lead to the consumption of SMS fees and it is impossible to continue sending SMS. Suggestions can be changed to monthly subscription, or prompt after reaching a certain amount.
