Your Phone Number Can Be Stolen Without Anyone Touching Your Phone
What’s actually happening SIM swap fraud works by targeting the weakest link in the chain, which usually isn’t your phone at all. It’s your mobile carrier.

SIM swap fraud is a type of cybercrime that targets mobile carriers rather than the phones themselves. Attackers gather personal information about their victims, often from data breaches or social media, to impersonate them to the carrier's customer service. By convincing the carrier they are the victim, the attacker can then request the phone number be transferred to a SIM card they control.
This allows the attacker to intercept calls and texts, including one-time codes used for identity verification. Victims often only realize something is wrong when they lose all cell service, which may be dismissed as a network issue. The Federal Bureau of Investigation and the Internet Crime Complaint Center warn that the losses from these attacks are often not reported separately, since they are typically categorized under other fraud types.
To protect against SIM swap fraud, set up a PIN or passcode with your carrier that is required for any account changes, avoid sharing sensitive information publicly, and consider using alternatives to SMS for security codes, such as authenticator apps or physical security keys. If your phone suddenly loses all service, especially after an unexpected account message, contact your carrier immediately.
