Key SMS Features and Capabilities in St Pierre and Miquelon
St Pierre and Miquelon supports 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 St Pierre and Miquelon according to current carrier configurations. This means businesses can only send outbound messages without the ability to receive replies through the same channel.

Support: Concatenated messages are not supported in St Pierre and Miquelon. Message length rules: Standard SMS length limits apply - 160 characters for GSM-7 encoding. Encoding considerations: Messages should use GSM-7 encoding when possible to maximize character limit. UCS-2 encoding reduces the character limit to 70 characters per message.

MMS messages are automatically converted to SMS with an embedded URL link. This means that any multimedia content you attempt to send will be delivered as a text message containing a link where recipients can view the content online.
