The 'SIM network disabled' problem in Samsung Galaxy M15 and F15 might be due to the 'Battery Optimization' or 'Network Power Saving' mode in the software. When the phone is idle for 15-20 minutes, the system turns off the network signal to save battery.
You can try the following solutions:
1. Check Adaptive Battery
Go to Settings > Select Battery.
In Background usage limits, try turning off the 'Adaptive battery' setting.
2. Check Battery Saver
Go to Settings > Battery > Make sure Power saving is turned off. Sometimes 'Limit CPU speed' or 'Turn off 5G' can also cause this.
3. Reset Network Settings
Go to Settings > General management > Reset.
Select Reset mobile network settings. (This will not delete any of your data, only Wi-Fi and SIM settings will be reset).
4. SIM Card Settings
Remove the SIM card and reinsert it properly.
Go to Settings > Connections > Mobile networks and try setting the 'Network mode' to LTE/3G/2G (Auto connect).
If these solutions do not make a difference, this might only be fixed through an upcoming Software Update, as it appears to be a software bug.
If you have difficulty finding any of these steps...
