Noted!

One issue still left: SMS are "relatively" easy to eavesdrop.

I am in the US. SIM reissuing scams are not uncommon and my own number was reassigned for half a week due to a technical glitch. During that time I had multiple conversations with customer support staff and it was ridiculous how many changes I could request without any verification or authentication.

The aim is to reduce the possibilities of getting robbed. Targeted attacks like sniffing SMSs of a user requires significantly more effort than just stealing their card.
