Number Portability

Number portability, which allows users to keep their mobile numbers when switching service providers, is not available in Timor-Leste. Users changing providers will receive new phone numbers.

Message Length and Concatenation

In Timor-Leste, concatenated message support is unavailable. Concatenation allows long messages to be split into segments and reassembled on the recipient’s device. Without this feature, keeping SMS messages short is advisable to prevent truncation or delivery issues.

Compliance Considerations

Adhering to local regulations is vital when sending SMS messages. It is recommended to consult with qualified legal counsel to ensure compliance with applicable laws. Here are some best practices for SMS campaigns in Timor-Leste:

  • Opt-in Consent: Secure opt-in consent from users before sending any communication, especially marketing or non-essential messages.
  • Daytime Communication: Restrict SMS messages to local daytime hours unless urgent.
  • HELP/STOP Support: Ensure SMS campaigns support standard HELP/STOP commands in the recipient’s local language.
