Market Conditions: Romania has a mature mobile market with high SMS adoption rates. The market is dominated by three major operators: Orange (39% market share), Vodafone (30%), and Telekom Romania (17%). While OTT messaging apps like WhatsApp and Facebook Messenger are popular for personal communication, SMS remains crucial for business messaging and authentication. Android devices hold approximately 75% market share, with iOS devices accounting for most of the remainder.
Key SMS Features and Capabilities in Romania
Romania offers robust SMS capabilities with support for concatenated messages and alphanumeric sender IDs, though two-way SMS functionality is limited and MMS messages are converted to SMS with URL links.
Two-way SMS Support
Two-way SMS is not supported in Romania through standard API providers. Businesses requiring two-way communication typically need to work directly with local carriers or use dedicated short codes with specific setup requirements.
Concatenated Messages (Segmented SMS)
Support: Yes, concatenation is supported across most Romanian carriers, though support may vary based on sender ID type. Message length rules: Standard GSM-7 encoding allows 160 characters per segment, while UCS-2 encoding allows 70 characters per segment. Encoding considerations: Messages using GSM-7 encoding (standard Latin alphabet) can be up to 160 characters, while messages using UCS-2 encoding (supporting special characters and Unicode) are limited to 70 characters before splitting occurs.
MMS Support
MMS messages are not directly supported in Romania. Instead, MMS content is automatically converted to SMS with an embedded URL link where recipients can view the multimedia content. This ensures compatibility across all devices while maintaining message delivery reliability.
Recipient Phone Number Compatibility
Number Portability
Number portability is available in Romania, allowing users to keep their phone numbers when switching carriers. This feature is fully supported and does not affect SMS delivery or routing, as the messaging infrastructure automatically handles ported numbers.
Sending SMS to Landlines
Sending SMS to landline numbers is not supported in Romania. Attempts to send SMS to landline numbers will result in a failed delivery with a 400 response error (code 21614). These messages will not appear in logs and accounts will not be charged for failed attempts.
Compliance and Regulatory Guidelines for SMS in Romania
SMS communications in Romania are regulated by ANCOM (National Authority for Management and Regulation in Communications) and must comply with both local telecommunications laws and GDPR requirements. The Romanian Data Protection Authority (ANSPDCP) oversees data privacy compliance for SMS marketing.
Consent and Opt-In
Explicit consent is mandatory before sending marketing or promotional SMS messages. Best practices for obtaining and documenting consent include:
Collecting written or electronic consent with clear terms of use
Maintaining detailed records of when and how consent was obtained
Specifying the exact purpose and frequency of messages
Providing clear information about how personal data will be used
Allowing users to modify their preferences at any time
HELP/STOP and Other Commands
Required Keywords: STOP, DEZABONARE (unsubscribe), and AJUTOR (help) must be supported
Language Requirements: Commands must be recognized in both Romanian and English
Response Time: Acknowledgment messages must be sent within 24 hours
Cost: Stop and help messages must be free for end users
Do Not Call / Do Not Disturb Registries
Romania does not maintain a centralized Do Not Call registry. However, businesses must:
Maintain their own suppression lists
Honor opt-out requests within 24 hours
Document all opt-out requests for compliance purposes
Regularly clean contact lists to remove unsubscribed numbers
Time Zone Sensitivity
Romania observes Eastern European Time (EET/EEST). While there are no strict legal time restrictions for SMS sending, best practices include:
Sending messages between 9:00 AM and 8:00 PM local time
Avoiding messages on Sundays and national holidays
Only sending urgent messages (like authentication codes) outside these hours
