SIM Swap Guidance
This guide explains how criminals can hijack your mobile phone number by tricking your provider into switching your service to a SIM card under their control. Once they have your number, they can intercept calls and texts – including the one‑time passwords used by banks and other services – and potentially access your accounts.
It also outlines key warning signs and provides practical steps you can take – like contacting your network operator immediately if things look strange, tightening account security and being careful about what personal details you share online.
