Regulations and Best Practices:
- Regulation: SMS traffic in Mexico is regulated by operators. Political content promoting a political candidate or cause is prohibited and may result in service termination. Content involving religious themes, inappropriate language, raffles, fraud, alcohol, and adult material is also prohibited.
- Opt-In Requirements: Opt-in is required, and any form of opt-in (web, call center, MO, etc.) is acceptable. Content providers must be able to demonstrate proof of opt-in if requested by operators or in response to a user complaint.
- Opt-Out Requirements: Opt-out is also required. Any form of opt-out (web, call center, MO, etc.) is acceptable, and content providers are responsible for removing opted-out users from their databases.
- End User Support/HELP Message: Programs should support a HELP message as a best practice.
- Allowed Sending Times for Marketing Programs: It is recommended to contact end users during their local daytime hours unless the message content is transactional, such as one-time passwords or account balances.
