The issue with the invalid MMI code on your Samsung Galaxy 8+ after switching the SIM card from an iPhone 7 may be related to the settings on your phone or the configuration of your carrier's network. Here are some steps you can try to resolve the issue:
- Update the APN settings: Access the APN settings on your phone and verify that the correct settings are configured for your carrier. You may need to contact your carrier for the correct APN settings.
- Verify the SIM card: Make sure the SIM card is properly installed and not damaged. If necessary, try using a different SIM card to see if that resolves the issue.
- Restart the phone: Sometimes restarting the phone can resolve issues with MMI codes. Simply turn off your Samsung Galaxy 8+ and turn it back on.
- Check for software updates: Make sure your phone's software is up to date by going to Settings > Software update. If an update is available, install it and check if that resolves the issue.
- Contact carrier support: If the issue persists, contact your carrier's support team for further assistance. They may need to make changes to your account or network configuration to resolve the issue.
