The secondary SIM card is consuming data
Cause:
- After the secondary SIM card is registered on the 4G network, the wireless network will send special data packets to it whenever needed. As a result, the secondary SIM card will consume a small amount of data even when it is disabled.
- When receiving an MMS message, the secondary SIM card will consume data.
- For detailed information about the consumed data, consult your carrier and ask for a detailed mobile data usage record that will contain the websites or IP addresses responsible for the data consumption.
Solution:

Phone Manager indicates that an app denied access to Internet consumes data
Problem:
After the user goes to and disables the Internet access permission for an app, Phone Manager indicates that this app still consumes data.
Cause:
By design, some system-level services (such as Google-related services) are not controlled by the Internet access permission settings. This means that they can still consume data even when Mobile data and Background data are disabled.
