How to be sure if I correctly installed something on my Smartphone?

[AC Question]

I bought a new smartphone some days ago. As soon as i inserted my sims messages from the service providers came about the mms and internet settings which i installed, as i was installing the last mms settings after clicking install and getting the installation complete message i wasn't sure i did it right so i did it once more and again the installation complete notification came.

Now i want to ask did i install it two times? has it consumed double the installation space? and where can i check how much space these settings consume?

I am using a Samsung Galaxy-J2 with Lollipop 5.1.1

I don't think you need worry about having entered the settings twice.... the second time will have had no effect. Any storage taken by the settings will be exceedingly small....a few kilobytes.
