Due to a recent hacker attack, no SMS messages are currently being sent to the following countries. For security reasons, these destinations have been temporarily blocked for SMS delivery.

Affected countries:  
- Bulgaria (+359)  
- Greece (+30)  
- Hungary (+36)  
- Romania (+40)

We are working on the fix and will inform you as soon as the service is available again.

Thank you for your understanding.
