SIM Card Management
Your SIM card is the gateway to network services, so any issues with it can lead to MMI code errors.
Navigate to your phone’s settings, specifically the SIM manager section, and try turning your SIM off and then back on. This process can reset your network connection on a more fundamental level than Airplane Mode.

For a more comprehensive approach, resetting your phone’s network settings can help. This process will erase all network-related preferences like Wi-Fi passwords and paired Bluetooth devices. It’s a bit more drastic but can effectively eliminate deep-rooted network issues.
