- 3xblah 8y agoThat is a fair point. How would you counter the following? When a call is made or a text is sent to a mobile number is is not addressed to anyone in particular. It is addressed to the number only. Mobile phone "MFA" only proves someone has access to the SIM card. It could be anyone. When a letter is sent to a mailing address, it can be addressed to a particular person. In many countries, there are laws that protect postal mail from tampering.
