Shopping in Pinduoduo, where can I send verification code without a mobile phone card?

When shopping in Pinduoduo, a mobile phone number bound to Pinduoduo did not issue the verification code of the mobile phone card. Mobile phones without mobile phone cards can't receive verification codes. The verification code sent by Duoduo Mall will be sent directly to the bound mobile phone number. Shopping in an app in Duoduo Mall will have a verification code. If the real-name authentication and mobile phone number are correct, you can receive the message of verification code within one minute, and copy and paste the verification code in the verification code column of Pinduoduo Mall to buy goods.
