Question

If someone has my cell number, can they find out my whole history with my cell phone number?
what is the most that someone can do with my cell phone number?

Answer

I used to work for a cellphone company, and the key question is whether the phone was directly in your name or not. If it is in your name? I will tell you what I could find out in five minutes behind the computer.brName, birthday, social security number, credit or checking account number depending on which one you use to pay your bill, state identification card number, when you started service, all the phone numbers you have called with it in the last year, and where you have travelled with that phone in the last three years.
