The network is normal, but I can't log in to China Mobile APP. I use my phone number to log in and say something wrong. I use SMS to say something about the network or system.

If you are trying to use China Mobile APP, the network is normal, but you can't log in and an error occurs, there may be the following reasons:

1. Incorrect account or password: Please make sure that the account and password you entered are correct. If you forget your password, you can try to set it again.

2. Network connection problem: Although you said that the network is normal, there may still be some network connection problems. Please make sure that your mobile phone is not connected to an unstable Wi-Fi network or a weak signal network.

3. The application version is too old: If your application version is too old, it may cause login problems. Please try to update the application to the latest version.

4. System problems: If your mobile phone system has problems, it may lead to login problems. Please make sure that your mobile phone system is the latest version and there are no errors.

5.APP server problem: Finally, if the above methods have not solved the problem, it may be that there is a problem with the APP server. You can try logging in again later, or contact China Mobile Customer Service for more help.

In short, you can try the above methods to solve the problem. If the problem still exists, please contact China Mobile Customer Service for more help.
