Key SMS Features and Capabilities in Niue
Niue offers basic SMS functionality with some limitations on advanced features like two-way messaging and concatenation.
Two-way SMS Support
Two-way SMS is not supported in Niue according to current carrier specifications. Messages can only be sent one-way from business/application to consumer.
Concatenated Messages (Segmented SMS)
Support: Concatenated messaging is not supported in Niue. Message length rules: Standard SMS character limits apply - messages should be kept within single SMS length. Encoding considerations: Use GSM-7 encoding when possible to maximize character limit per message.
MMS Support
MMS messages are automatically converted to SMS with an embedded URL link to view the media content. This ensures compatibility while still allowing rich media sharing through a web-based alternative.
Recipient Phone Number Compatibility
Number Portability
Number portability is not available in Niue. Phone numbers remain tied to their original carrier.
