Didi needs a code to register or log in, but it never comes. Use a Chinese SIM, or switch the login method.
Foreign SIMs often miss Chinese SMS codes.
What you'll see
If the code never arrives, the SMS is being blocked before it reaches you:
Verification code failed · SMS not received
滴滴 App 显示：验证码发送失败 / 未收到短信
Error-text level: L2 (observed wording). Exact in-app strings are being verified against a live device.
Why it happens
Foreign SIMs often cannot receive Chinese short codes, or your carrier blocks them. A Chinese SIM fixes it because the code is sent from a local number.
Fastest fix, free:Restart your phone and tap resend; if it still fails, use a Chinese SIM card or ask the hotel for a temporary one.
