How to modify the SMS receiving number of online shopping verification code

Hello, I don't know where the online shopping you mentioned is, but it is usually changed in account management. Provided that you can receive the verification code with your old mobile phone number. If you can't, it's a little more trouble. Contact the website customer service or call the hotline. They may prompt you what to do, and prepare your ID card, email address and other commonly used verification. If you are satisfied, please accept it. If you don't understand, please ask questions. Thank you.
