If you recently have become the owner of a cell phone, you might not be familiar with your own number. Perhaps you forgot what the representative working at the cell phone store told you or you lost the paper you wrote it on. Not to worry, there are a few simple things you can do to determine your own cell phone number.
Call another phone equipped with caller-ID from your cell phone. This is the easiest method to determine your own cell number, because the calling number will be displayed on the screen. Make sure to write down that number in case you forget it again.
Look in your phone to figure out the cell number another way. Look in the set-up information on your cell phone and it will tell you what your number is.
Call your cell phone provider if you still can't figure out your number. It will be on file. The customer service representative can tell it to you after you verify who you are with a security question or password to make sure no one is hacking your account.
