Xiaomi's mobile phone can surf the Internet normally, but it can't search the weather.

If you can't get online when using data traffic, I suggest you check whether some software or all software can't get online first. If some software can't access the Internet, please click the network assistant or the third-party security management software to check whether the software can't access the Internet. If all software can't access the Internet, I suggest you check whether the access point of the network is set correctly. Please refer to/thread-409172-1-65438 for access point settings. At the same time, it is recommended to switch to WIFI network for operation. If the problem remains unresolved, it is recommended that you back up important data first, and then enter recovery mode (power off, press and hold the volume up+power on key to enter recovery mode) to clear all data. Don't restore the data temporarily after booting, download the software directly to see if it can be used normally.

A more detailed description of the problem will help netizens understand your troubles and help you solve the problem more accurately. Thank you for supporting Xiaomi mobile phone!
