Your SMS verification code never arrives
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:
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.
Every case shows the diagnosis and the first step - free. The full step-by-step fix for this exact case, the decision tree, and the offline kit are $9.99.
When the fast fix isn't enough
In the kitWhen the code keeps failing, the kit gives the carrier-unblock steps and a login path that works without a Chinese SIM.
1. The lookup table
Which carriers block Chinese SMS and the exact call to lift the block.
2. The trigger matrix
When a Chinese SIM is mandatory vs when roaming is enough.
3. Offline printable version
The unblock script and login steps as a printable card.
One map is open in your hands. The other is rolled up in your bag.
One question, two paths. Your answer picks the road.
Direct binding fails far more often than this two-hop route.
If nothing works
If you still cannot log in:
- Ask hotel staff to help you get a Chinese SIM.
- Use Didi inside the WeChat mini-program, which may need less verification.
- Contact Didi support through the app for an alternative login.
Four levels deep — a declined card never leaves you on the kerb.
Showing the screen to the driver beats any translation.
