First of all, in the first case, the verification code you entered for your mobile phone number times out. The second is whether the reserved mobile phone number bound to your credit card is correct, and the third is whether you have received a verification code text message from JD.com on your mobile phone. If these are correct, you can activate by filling in the verification code on the text message sent. If you have any questions, please call JD.com’s customer service or consult online.
