Alipay adds SMS check code of bank card. How can it be invalid if it is collected so slowly?

Dear, the failure to receive the verification code may be a problem with the communication gateway, and the verification code has been delayed. Dear, you can try the following methods: 1. Turn off the phone 1-2 minutes; 2. At present, some firewalls of smart phones also have shielding function. You can take out the sim card and replace it with an ordinary or family mobile phone to receive short messages. 3. If it still doesn't work, please try again next time ~
