A verification code will be sent to your entered phone number. Please fill it in correctly.

Frequently Asked Questions (FAQ)

What if the upgrade tool page doesn’t open?

What if I get Failed to fetch after entering my phone number and clicking to send the code?

This is also a network issue. Please try:

Switching to a different network

What happens if I enter the wrong PIN on the tool page?

You have 9 attempts. If exceeded, the page will show Error 403 or Forbidden, and the account will be locked for 30 days.
Please wait patiently for the lock period to expire before trying again. Do not keep retrying during this time.

Each time you enter a verification code to log in also counts as an attempt, so do not refresh and repeat unnecessarily!

What if I forgot my PIN?

The PIN cannot be recovered. You can only try to recall it. Please operate carefully to avoid being locked out.

We recommend writing down each PIN you try to avoid repeating the same attempts.

What if my phone number is no longer available?

If you have not set an emergency contact, please contact your carrier to retrieve your phone number and then use the tool.
If you have set a recovery contact (formerly called "emergency contact"): currently, the tool does not support logging in via recovery contact. Please reach out to our official support team:
App chat: private message Team Mixin (@7000)
Or click the website chat bubble to contact support, and we will assist you.

What if after using the tool, I still get a PIN error when logging into Mixin?

Please wait 7 days and try again.
