Solving the ‘Connection Problem or Invalid MMI Code’ Issue on Android

If you’re an Android device user and have stumbled upon the error ‘Connection Problem or Invalid MMI Code’, then you know how frustrating it can be. MMI codes, short for Man-Machine Interface codes, are special codes that you input into your phone dialer for certain functions, like checking your balance with #BAL. Occasionally, inputting these codes can result in an error. This tutorial will take you through updated methods to resolve this issue effectively.

Comprehensive Guide to Resolving the ‘Connection Problem or Invalid MMI Code’ Error

If you’ve faced the pesky ‘Connection problem’ or ‘Invalid MMI code’ error on your Android device, it’s time to say goodbye to frustration. MMI codes, which often start with an asterisk or hash and might resemble #BAL for a balance check, can sometimes cause these errors. But rest assured, there are several solutions that should help clear up this issue for you.

Troubleshooting ‘Invalid MMI Code’ Errors

  • Reboot Your Android Device: A classic fix that tends to solve an array of issues. To do this, press and hold the Power button (and Volume button on some devices) until the options menu appears, then select ‘Reboot’. If you’re lucky, this simple action can clear the error.
  • Modify the Prefix Code: Altering the prefix code can be another quick fix. For example, if the MMI code is (*#06#), adding a comma (*#06#,) or plus symbol (*#+06#) at the end can sometimes bypass the issue.
  • Check Radio and IMS Service: Access hidden menus to verify underlying issues with these services:
    • Open your dial pad.
    • Type in (*#*#4636#*#*).
    • In the revealed menu, choose ‘Phone Information’ or ‘Device Information’.
    • Run a ‘Ping test’.
    • If prompted, turn off the radio and allow the device to restart.
  • Inspect Network Settings: Sometimes the error could be due to your network settings being amiss. Navigate to ‘Settings > Network & Internet > Mobile Networks’. Here, check that your network settings are configured correctly and attempt to manually select your network operator if necessary.

It may take several attempts to reconnect, but persistency here usually pays off.
