Will you change the bound mobile phone and send a text message to the original mobile phone?

Generally speaking, change the bound mobile phone number (if the mobile phone card is lost or the mobile phone number is not used). If there is a bound mailbox, you can generally change the bound mobile phone number through mailbox verification. If you don't have a bound email address, you have to get a replacement card or the original mobile phone number to get a verification code to verify and change the bound mobile phone number. If you can't get your card back or your original mobile phone number back, you can try to appeal to customer service.
