This could stem from various issues, ranging from minor software glitches to hardware problems.
Troubleshooting Steps: Let's Start Simple
Before resorting to complex fixes, let's try some easy troubleshooting steps that often resolve the problem:
- Restart Your Phone: The simplest solution is often the most effective. A simple restart can clear temporary software glitches that might be causing the issue.
- Check SIM Card: Ensure your SIM card is correctly inserted and not damaged. Try reseating it β gently remove and reinsert the SIM card.
- Check Network Settings: Go to your phone's Settings > Mobile Network and ensure that the correct network mode (e.g., 4G/LTE, 3G, 2G) is selected. You might also try toggling airplane mode on and off.
- Software Updates: Make sure your Redmi 3S is running the latest available software version. Outdated software can sometimes contain bugs that cause this error. Checking for updates is usually found in Settings > About Phone > System Updates.
- Factory Reset (Last Resort): As a final software-based solution, consider a factory reset. Important: This will erase all data on your phone, so back up important files beforehand. This option is found within Settings > System > Reset options > Factory data reset.
Advanced Solutions: When Simple Steps Fail
If the basic troubleshooting steps don't work, the problem might be more complex. Consider these advanced solutions:

Only attempt this if you are comfortable with technical procedures and have thoroughly researched the process for your specific Redmi 3S model.
