SIM swapping has emerged as one of the most financially damaging forms of identity theft in recent years.

The rise of mobile authentication and the ongoing reliance on text‑message verification have made this threat particularly potent. From retail banking to digital wallets, companies and consumers are coping with sharper losses and more frequent attacks. Read on for a data‑driven look at how SIM swapping is evolving and why it matters.
