My Samsung Mobile get Invalid MMI Code How to fix this issue

The first way to try to fix an invalid MMI code would be to restart the smartphone. Going to network settings and then holding the #Power” button and the #Home” button at the same time until the phone turns off and starts vibrating will restart the smartphone
MMI code is the code that we enter over the phone which contains * and hash # characters. Solution: 'Connection problem or invalid MMI code' indicates a problem with the network (i.e poor signal) or wrong MMI code have being entered by the user

I am sure you are intelligent...... but for us older users, please slow down your speech! I am 70, not 15. I just want to increase the rings on my samsung S8. Can't find any instructions that work..... the MMI code was invalid.

[@RobCLynch]

How come I'm not allowed to watch some videos from America or Europe, yet it's perfectly ok to populate my search results with stuff from Asia? Could it be that the phone companies have flooded the internet with stuff that doesn't work, so that we can't unlock our phones?

Bro,Can u help me? in my J2 prime? it doesnt work bro i hope u can help me please...thankyou in advance

[@TECHMAJA]

follow this step hope, your problem will be fix I imagine in the world tons of device is there, people think that this will work for every device, but most of the device, some code do not run, because every new device have his own interface, hopefully, you follow this method Go to Dial Pad Dial *#*#4636#*#* (No need to press the call button, it will automatically appear the service mode) Select the ‘Device Information or Phone Information’. Select ‘Run Ping Test’. Click on ‘Turn Radio Off’ Button Then, click on ‘Turn on SMS over IMS’ Reboot your phone & Check That’s its
