Redmi mobile data connection error code (1 104)

First of all, I suggest you restart your mobile phone. If it doesn't work, please refer to:

1. Please confirm whether the SIM card type of the mobile phone corresponds to the network type supported by the mobile phone;

2. Ensure that the SIM card of the mobile phone has no downtime arrears (this situation is most easily overlooked);

3. Go to Mobile Phone Settings-Mobile Network-Access Point Name, and click Select Reset to Default Settings to try.

4. Check whether there is traffic monitoring software (including the network assistant that comes with the system) to forcibly shut down the network. If yes, you can cancel the upper limit of flow or adjust it to an appropriate value;

At present, most software and web pages need to use network access points. If there is no connection, try changing the access point to a network.
