SIM swap fraud/scam occurs when a fraudster pretends to be a customer of a mobile operator, either online or in person, and is able to convince the phone company to issue them with a replacement Sim for their phone.

Fraudsters are able to do this by claiming a false identity and using people's personal details that have  been stolen, sometimes through malware or cyber-attacks.

The victim's SIM card stops working and the fraudster is able to access calls and texts, as well as any other online services that require security codes to be sent to the user's mobile number. 

Once SIM swap fraud has occurred, it is not instantly noticeable to the victim. Extended loss of signal is the initial sign that SIM swap fraud has taken place, as the control has been switched to another mobile device. Contact your phone provider to check if it is a widely known issue or isolated to your device.
