USSD codes to block numbers on ZTE Grand X Max

Alternatively, there are some USSD codes that you can use to block all incoming calls.

This feature is called Call Barring. It is important that these codes will not block specific numbers, instead, they will prevent all the calls that you receive (not messages). So this is only useful if you are working or gaming on your ZTE Grand Max device.

So here is how to enable Call baring:

  • *353*(Set a password)# (Keep the password in your mind. You will need it to cancel the Call, Barring)

Example: *353*993365# – The password is highlighted. You can set any password as you want.

Here is how to Disable Call barring:

  • #353*(enter password)#

Example: #353*993365#

You can also check whether you have enabled Call Baring:

  • *#353#

That is it. Hope you have successfully been able to block numbers in your ZTE Grand Max device.
