FBI figures put SIM swapping losses at almost $26 million in a recent reporting year, with an average above $26,000 per victim. Separate reporting describes a 240% surge in cases, around 90% of which occurred without any victim interaction.

That Last Figure Changes The Advice

Consumer guidance on account takeover is built on the assumption that the victim does something: clicks a link, answers a call, enters a credential. Awareness training is the standard response.

If most SIM swaps involve no victim interaction, the victim had no opportunity to behave differently. The failure occurred entirely at the carrier — a person or process transferred a number to somebody who was not the subscriber.

It Is The Help-Desk Problem In A Different Industry

This is the same mechanism this desk has filed all year: at M&S in 26-0413, at PowerSchool in 26-0113, and — on the attackers’ own account, which the company has not confirmed — at Abbott in 26-0714. Someone with authority to restore access was persuaded to grant it to the wrong person.

Carriers face the additional difficulty that legitimate number porting is a regulated consumer right which they are obliged to make straightforward. The friction that would stop fraud is friction a regulator has required them to remove.

The Loss Figures Understate It

Reported losses capture direct theft. They do not capture the accounts reached afterwards using the number as a recovery channel — the property filed at 26-0212 and 26-0205.

A successful swap is rarely the objective. It is the step that makes everything else possible, and the downstream losses are recorded, if at all, as separate incidents with different causes.
