Romania

Some carriers in Romania (such as  DiGi) seem to have issues with SMS responses. The messages do arrive and SMS to Romania one-way is viable. We are investigating options to extend reach. These carriers should work for 2-way SMS:

• Orange Romania
  
• Telekom Romania (f.d. Cosmote)
  
• Vodafone Romania
