Last reviewed: 1 June 2026
SIM-swap fraud transfers a victim's mobile number onto a SIM the attacker controls, intercepting the calls and SMS codes used to verify banking, wallet, email, and messaging accounts. Once the number is hijacked, the attacker can reset passwords and drain accounts.
In the Dominican Republic, where mobile numbers anchor access to banking apps, wallets, and WhatsApp, a SIM swap can be especially damaging. Attackers often gather personal details beforehand through phishing or data leaks to impersonate the victim to the carrier.
How this scam works on the Dominican Republic
The attacker first collects personal information about the victim — name, ID (cedula) number, date of birth, security answers — through phishing, social engineering, or leaked data. They then contact the mobile carrier (or use an insider) posing as the victim and request that the number be moved to a new SIM, claiming a lost or damaged phone.
Once the swap succeeds, the victim's phone loses service while the attacker receives all calls and SMS. The attacker uses verification codes to reset passwords and take over banking apps, wallets, email, and WhatsApp. A hijacked WhatsApp is also used to message the victim's contacts requesting urgent money.
Victims often notice only when their phone abruptly loses signal and accounts start changing.
Common red flags
- Your phone suddenly loses signal or shows 'no service' for no clear reason
- Unexpected notifications of SIM changes, password resets, or new logins
- Being locked out of banking, email, or WhatsApp accounts
- Contacts reporting odd messages or money requests from your number
- Carrier confirming a SIM change you did not request
- Phishing messages beforehand asking to confirm personal or account details
- Verification codes arriving that you did not request
How to protect yourself
- Use app-based authenticators or security keys instead of SMS codes where possible
- Set a PIN or passcode with your mobile carrier to authorise SIM changes
- Never share verification codes, even with someone claiming to be the carrier or bank
- Be cautious about how much personal information you share online or by phone
- Act immediately if your phone loses service unexpectedly — contact your carrier
- Enable account alerts so you are notified of password and login changes
How to report it
- Contact your mobile carrier immediately to regain control of the number
- Notify your bank and any affected wallet or account providers to freeze access
- Report to the Dominican police anti-cybercrime division (DICAT) and the Procuraduria
