Does the OP know how to access the phones internal “counters”, and verify that much data has passed through their phone? Otherwise, someone could have cloned it, and she would get the bill as well.

Most phones have some counters which can be reset, and others that can not, so she can prove that “HER” phone never accessed/received that much data.
