Does Pinduoduo charge for texting himself?

No matter what kind of wallet or payment software, don't set up confidential payment, because there are many risks in confidential payment, so it is normal for you to have abnormal funds and make many inexplicable deductions. There are also many wallets bound to bank cards. You don't need to enter or take a photo of the bank card number, you can directly bind it by entering the mobile phone number. As long as the mobile phone number is the reserved mobile phone number of the bank card, you can bind the SMS verification code.
