The Mobile Country Code (MCC) for Eritrea is 657. This code is essential for routing international SMS messages correctly to Eritrean mobile numbers.
According to current provider capabilities, Eritrea, under its sole operator EriTel, does not support two-way SMS. This restricts interactive messaging campaigns and automated response systems.

Restricted content includes gambling, adult material, unauthorized political or religious content, and cryptocurrency promotions. Content filtering may block messages with restricted keywords or unapproved URLs.

Key best practices include obtaining explicit consent, localizing content, respecting time zones, and managing opt-outs efficiently. Also, consider using clear call-to-actions, testing messages, and monitoring delivery rates.
