Need to unlock

a sim card is locked BECAUSE it is not active,in order to unlock a sim card,you need to either,pay the balance owed,buy a new monthly service,open a new contract with a cell service or return the sim card to whom it belongs to,we at fixya XANNOT GIVE YOU A NUMBER TO UNLOCK YOUR SIM CARD,there is a reason why it is locked,if it was easy to get a code,then anyone could steal your phone and use it and you couldnt stop its use for at least a month.
