Who called from 9195851939

Not sure about this number

It's From Text Plus i just called the number and it said that's what it is but i don't know why they texted or how they know my real name

Some people are saying they are calling them by the fake name they use on Facebook so probably they are using an app you or one of your friends authorized on there.  They possibly want to hack your Yahoo account by getting you to click on a link.  Report the Yahoo ID to Yahoo abuse and the phone number to [email protected]
