4. Check SIM Card Compatibility:

Ensure that your SIM card is compatible with your phone. Some phones require a specific type of SIM card, such as a nano SIM or micro SIM. If your SIM card is not the correct type, you may encounter the “Invalid SIM” or “No SIM” error.

5. Update Your Phone’s Software to remove invalid SIM error:

Outdated software can sometimes cause compatibility issues with your SIM card. Check for any available software updates for your phone and install them to ensure that your phone’s software is up to date.

6. Reset Network Settings:

If the above steps don’t work, you can try resetting your phone’s network settings. This will reset all network-related settings to their default values, which can sometimes resolve network connectivity issues. Note that this will also delete any saved Wi-Fi passwords.

7. Try Another SIM Card to remove the SIM error:

If you have access to another SIM card, try inserting it into your phone to see if the issue is with the SIM card or the phone itself. If the new SIM card works without any issues, the problem likely lies with your original SIM card.

8. Contact Your Mobile Service Provider:

If none of the above steps work, it’s a good idea to contact your mobile service provider. They can check if there are any issues with your SIM card or account that may be causing the “Invalid SIM” or “No SIM” error and provide further assistance.
