Missing "Cellular" ... Instead "Mobile Data" appearing...

Following is not question. It is information which might help others and hence posting this. I am new to iPhone community and could not find a better way to post this info.

In my iPhone 7plus with iOS 11.2.6, I found that in Settings, "Cellular" option has been replaced with "Mobile Data" and "Cellular Data" is replaced with "Mobile Data Options". No where this information is available and it took a while for me to figure this out.
