I tied the package payment to Unicom's mobile phone number, so I couldn't receive the verification code.

You can check whether the phone is set to block spam messages. If so, I suggest you cancel the SMS interception. If nothing is set but the verification code is not received, you can check whether it is normal to receive verification codes from other services. If other verification codes are normal, you can report them to the customer service who provides this service. If all the verification information is abnormal, you can call the customer service hotline 100 10.
