Notes
The Cayman Islands (KY) allows both alphanumeric and numeric sender IDs. However, it is important to note that generic sender IDs such as INFO, SMS and NOTICE are not allowed. When sending A2P SMS messages, specific guidelines must be taken into account. P2P traffic is prohibited and content related to politics, religion, unsolicited promotion or gambling is not allowed. Beyond these guidelines, there are no additional content restrictions beyond those stated in our Acceptable Use Policy. It is important to be aware that the rules for text messaging may change and we strive to keep the information updated and accurate.
