Mobile data is cut off when Nubia Z11 is on standby with dual SIM cards

This is caused by a system conflict. It is recommended to double-clear the process. The specific operations are as follows: After downloading the flash package, turn off the phone. Press the Changan volume down button and press the power button. The phone will enter the English interface. Select the longest English. For some models, it is the second item. The phone will restart into rec mode, select Chinese, and then follow the prompts to restart with dual clear.
