2. Reinsert SIM Card: Turn off the device, carefully remove the SIM card, wait for a few moments, and reinsert it securely.
3. Restart the Device: Sometimes, a simple restart can resolve SIM card configuration problems.
4. Reset Network Settings: Go to the device's settings, navigate to "Network & Internet" or "Mobile Network," and select the option to reset network settings. This can help clear any configuration conflicts.
5. Update Software: Ensure the device's software is up to date by going to "Settings," selecting "About Phone," and checking for any available updates.
6. Clear Cache: Use the device's storage settings to clear the cache for SIM-related apps or services.
