Frequently Asked Questions

Nicaragua's mobile market is dominated by Claro and Movistar, with a preference for OTT apps, but SMS remains important for business communication and authentication, especially in areas with limited internet access.
MMS is not directly supported. Attempts to send MMS result in conversion to SMS with a URL link to the media content. This maintains compatibility with local networks while ensuring message delivery.
Prohibited content includes gambling, adult material, illegal products/services, cryptocurrency promotions, and unauthorized political campaign messages. Financial and healthcare messages have specific regulations.
Comply with general telecommunications rules by TELCOR. Prioritize explicit opt-in consent, honor opt-out requests (STOP, CANCELAR, NO, AYUDA, HELP), and maintain thorough documentation of consent and opt-out activity.

Process opt-out requests within 24 hours, send a confirmation, and maintain a centralized opt-out database. Regularly audit your list for compliance. Support opt-out keywords in Spanish (STOP, CANCELAR, NO) and English.
Keep messages under 160 characters, include clear calls to action, and personalize with the recipient's name. Respect local holidays, use formal Spanish, and send 2-3 messages per week maximum.
