That's how I collect red envelopes now. If I have a bank card, will I send a message to my mobile phone every time I spend it?

Wechat red envelopes must be bound to bank cards, which is the real-name registration system. You can bind your own bank card or your parents' bank card. If it's your own bank card, use your mobile phone number and a text message will be sent to you. If it is a parent's bank card, it can be unbound after binding. As long as there is money in WeChat change, consumers will pay with WeChat change and will not send text messages. That is, if you don't use a bank card, there will be no SMS notification.
