So instead of using your mobile phone that will charge you really high, you opted to just open your VoIP account. Moreover, you then make longer chatting with your mom as this cost you little than using your phone. Then a friend of your memorized already your account credentials, and then tried at home to use the account with the same set up of your provider. From then on, you are already having Fraud issues. You waited for your bill and saw the huge amount of dollars that you need to settle. How will react to this issue? Will you cry over spilled milk, explain to yourself that it was never you who uses the account or go to the police and file Fraud case?
A fraud case usually takes more years to be resolved and for some it was never resolved. You have to be financially and physically ready for this battle. It’s not easy to prove that it was never you after all when you have your credentials and it’s never easier to explain why somebody else does have your account which is supposed to be only yours.
