If you’re a Samsung user, you may have encountered connection problems or received an “Invalid MMI Code” error message when trying to make a call or send a text. This can be frustrating, but there are a few simple steps you can take to fix the issue.
First, check your network connection and make sure you have a strong signal. If you’re using Wi-Fi, try turning it off and switching to your mobile data or vice versa. You can also try turning on airplane mode for a few seconds and then turning it off again to reset your connection.
If that doesn’t work, you can try resetting your network settings. Go to Settings > General Management > Reset > Reset Network Settings. This will reset all network settings, including Wi-Fi, Bluetooth, and Mobile data, so be sure to have your Wi-Fi passwords handy.
If you’re still experiencing connection problems or getting the “Invalid MMI Code” error, you may need to contact your mobile carrier for further assistance. They can help you troubleshoot the issue and may need to reset your network on their end.
By following these simple steps, you can hopefully fix the connection problem or invalid MMI code on your Samsung device and get back to using your phone without any issues. Remember to always check for software updates and keep your phone’s firmware up to date to prevent any future connectivity issues.
