The reason why Xiaomi mobile phones can't use data is mainly because of the reasons you set and the surrounding signals. If the setting is not correct, it is likely to cause traffic, although it has been involved in the core of the mobile phone, but it cannot be used. If you find that your phone can't be used under the condition of normal connection data, it means that there is a problem with your settings, and you need to find the settings and find the restore settings to factory settings.

All the features of the settings can be restored without deleting the content. At this time, if the surrounding signal is not blocked, then your traffic will be available. At the same time, if you notice that there is a large amount of reinforced concrete in the vicinity around you.

It is best to turn on the traffic without obstructions, and the signal is best at this time.
