Why didn't I send a text message when I paid Alipay?

If you pay by bank card, and your bank card has SMS reminder information, that is, account reminder, you will be sent SMS, but if you pay by the balance in Alipay or Yu 'ebao, you will not be sent SMS. Generally, your mobile phone will push messages to you when there is no network, so you won't be informed, but you can check this transaction in Alipay bill or see if there is any message reminder in the friends section.
