Redmi Note 3G/4G : 3G, WIFI Internet issues & Solution

Why does my Redmi Note not use data traffic? 

If your Redmi Note goes without Internet access/data traffic during use, you first need to confirm that your phone bills are not overdue, and the current signal is good, then try to solve the problem with the following solutions: 

1.  Check if the top right of the data network identification is normal (G / E / 3G / H // H + 4G); 
2.  After restarting the phone, manually re-switch data traffic; 
3.  Check whether the system comes with Network Blocking App or if you have reached the upper limit of your current data usage network settings. We recommend that you limit the operation to cancel or re-set the upper limit of your data usage network settings; 
4. If your phone is installed with a network security management App, we recommend that you check whether the problem was caused due to such software settings. 
5. We recommend that you try to reset APN access point settings, methods of operation: System Settings - mobile network - Access Point Name (APN) - reset to the default settings, try to choose "net" access point attempts; 
6. Prolonged use may cause the system to generate a lot of junk files, which impede the normal operation of the system. It is recommended that you test (after backup) if resetting to factory settings will solve the problem.
7. If the above methods are still unable to help you solve the problem, it is recommended that you bring the phone to the nearest Xiaomi authorized repair point for testing.
