My wife has a Kyocera Rio phone with MTS... on our last bill there was a charge for 409 text to email messages that she never sent. Is there a way that someone could have cloned her phone and sent these messages but still left it operational so she got calls, etc as normal? After much arguement, MTS waived the fees for it ($100 plus) but they said there was no way to turn this service off. What can I do so this never happens again?
