How can I activate roaming service? How much does it cost?

• If you are using a postpaid plan, you can activate a roaming service by sending free of charge SMS with text “А” to number 1210.
• Calling 123 from your mobile phone (the price per call for customers of postpaid plans in Yettel Bulgaria is 0.024 BGN and 0.10 BGN/min. for customers using prepaid plans. Prices are VAT inclusive).

Important: After July 1, 2014 you may use Alternative roaming service providers (other than Yettel) in the European Union, while continue using roaming from Yettel in the rest of the world.
