How to Fix Delta iOS Executor Chinese Errors 40021 & 40000 (November 2025)

It has been a month since the Delta Executor started offering Direct Install option for its iOS users across the world. Unlike VNG, Delta iOS Direct Install can be used anywhere in the world without any hassle.

Similar to Android and VNG versions, Delta Direct Install has a couple of issues and errors that people might face while using it on their iPhone or iPad.

The error Delta IOS users are currently having is a Chinese error 400021, and 40000. Since the error pop up is in the Chinese language, many people don’t know what does it mean.

To help you out, we have translated that Chinese error message in English.

The error message states,

“Please contact customer service, the number of devices installed this month is: 40021, which exceeds the total monthly installable device count of 40,000.”

To offer Direct Install option to our users, we have been purchasing Apple Enterprise Certificate that has its monthly installation limit.

For the current package, it was 40,000 limit, which has been exceeded in a couple of weeks, leading to this Chinese error 400021 on Delta IOS.

Unlike other issues and errors, there is nothing that can be done from your end to resolve the Chinese error 40021 on Delta iOS Executor.

Since the issue is happening from the Certificate Providers, we have in touch with them to increase the limit, offering you seamless experience.
