Part of: SIM Swap Scams
Last reviewed: 1 June 2026
SIM swap fraud is a growing threat in Ukraine, where mobile-banking adoption through Monobank and PrivatBank is exceptionally high and most account authentication relies on SMS OTP delivery. The National Bank of Ukraine and Cyberpolice have issued multiple warnings as the fraud adapts to the Ukrainian mobile operator landscape.
Attackers obtain personal data from dark-web market listings seeded by Ukrainian data breaches, then impersonate victims to Kyivstar, Vodafone Ukraine or lifecell customer-service channels to execute a fraudulent SIM replacement.
How this scam works on Ukraine
Armed with the victim's full name, passport number and phone number, the attacker calls or visits a Kyivstar or Vodafone Ukraine service centre and claims the SIM has been lost or damaged. A fraudulent SIM replacement is issued using forged or manipulated documents.
Once the attacker controls the victim's number, Monobank or PrivatBank password-reset flows are initiated, with all verification codes delivered to the attacker's SIM. Within minutes, funds are transferred to mule accounts or converted to crypto.
Ukrainian victims often discover the fraud only when their phone displays 'Немає обслуговування' (No Service) and they are unable to receive calls, by which point significant funds may already have been moved.
Common red flags
- Your Kyivstar, Vodafone Ukraine or lifecell phone suddenly shows no service
- You stop receiving calls and SMS without a technical reason

How to protect yourself
- Request a SIM-change password ('пароль для заміни SIM') from your mobile operator
- Switch Monobank and PrivatBank to biometric or authenticator-app login rather than SMS OTP
- If you lose signal unexpectedly, call your operator immediately from another device
- Monitor your accounts for small test transactions that often precede larger fraud
