The gist of it is:
To find the cell phone number on an iPad
Tap Settings
Tap General
To find the cell phone number using an Android tablet
There are a variety of different Android operating systems, and you may find subtle variations with the following instructions:
Tap the Settings icon
Tap the "About device" option
Tap the "Status" option
The cell phone number is called "MDN" which is short for Mobile Directory Number
The telephone number is called "Cellular Data Number"
Either Titillating has never owned a tablet or was (or is) clueless. It never ceased to amaze me why some people just find it impossible to just say, "I don't know". Or why even bother making a reply in the first place if you aren't sure? These kind of people want to sound knowledgeable but end up sounding like a moron. Millions of dollars are wasted on car repairs, what school to attend, what medicine to take (or not to take) because some egocentric nut gives wrong information.
