Compliance considerations Calilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. This table lists some general best practices.	Calilio offers SMS delivery to India through both International and Domestic gateways. International: No DLT registration is required. Messages are transmitted via mobile operators’ International Long Distance Operator (ILDO) connections. Messages are sent using random ILDO-approved short codes in the format 5NNNN—5NNNNNNNN (e.g., 54321). Messages from international customers bypass India’s Do-Not Disturb (DND) database and are delivered without any time-of-day restrictions. Domestic: Completion of company and Sender ID registration within the mobile operators’ DLT portal is necessary before submitting a registration request to Calilio. Messages will be delivered with the customer’s DLT-registered Alphanumeric Sender ID. Currently, Calilio only supports registration for DLT-registered Alphanumeric Sender IDs but is exploring adding support for promotional messages via DLT-approved 6-digit Sender ID in the near future. Sending firearms, gambling, adult content, money/loan, political, religious, controlled substance, cannabis, and alcohol related content is strictly prohibited. Sending messages with shortened URL is not allowed. Calilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. The following are some general best practices: Get opt-in consent from each end user before sending any communication to them, particular for marketing or other non-essential communications. Only communicate during an end user's daytime hours unless it is urgent. SMS campaigns should support HELP/STOP messages, and similar messages, in the end user's local language. Do not contact end users on do-not-call or do-not-disturb registries.
