Bahamas SMS Best Practices, Compliance, and Features

Bahamas SMS Market Overview

Market Conditions: The Bahamas has a well-developed mobile telecommunications infrastructure with SMS being a widely used communication channel. The market primarily operates on GSM networks, with major carriers providing comprehensive coverage across the islands. While OTT messaging apps like WhatsApp and Facebook Messenger are popular among locals and tourists, SMS remains crucial for business communications and notifications due to its reliability and universal reach.

Key SMS Features and Capabilities in Bahamas

The Bahamas supports standard SMS messaging capabilities with some limitations on advanced features like two-way messaging and sender ID preservation.

Two-way SMS Support

Two-way SMS is not supported in the Bahamas according to current carrier configurations. This means businesses cannot receive replies to their messages through standard SMS channels.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenated messages are supported, though availability may vary by sender ID type.
Message length rules: Messages follow standard SMS length limits - 160 characters for GSM-7 encoding and 70 characters for UCS-2 encoding before splitting occurs.
Encoding considerations: Both GSM-7 and UCS-2 encodings are supported, with UCS-2 being particularly important for messages containing special characters or non-Latin alphabets.

MMS Support

MMS messages are not directly supported in the Bahamas. Instead, when attempting to send MMS content, it will be automatically converted to an SMS containing a URL link where recipients can access the multimedia content. This ensures message delivery while maintaining the ability to share rich media content.

Recipient Phone Number Compatibility

Number Portability

Number portability is not available in the Bahamas. This means mobile numbers remain tied to their original carriers, which can simplify message routing and delivery processes.

Sending SMS to Landlines

Sending SMS to landline numbers is not supported in the Bahamas. Attempts to send messages to landline numbers will result in a failed delivery, specifically generating a 400 response with 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 Bahamas
