## Who regulates A2P SMS in Uruguay?

Application-to-person messaging to Uruguay is overseen by the Unidad Reguladora de Servicios de Comunicaciones (URSEC), which licenses the operators that terminate A2P traffic and sets the conditions those routes run under. BroadNet delivers into Uruguay over direct operator connections — Antel, Movistar Uruguay and Claro Uruguay — rather than through resold or grey routes, so the sender ID, the delivery receipt and the audit trail all come back from the licensed path.

- Telecoms regulator: Unidad Reguladora de Servicios de Comunicaciones (URSEC).
- Direct operator routes: Antel, Movistar Uruguay and Claro Uruguay.
- Sender-ID registration: URSEC + operator sender ID registration. Spanish supported.
- Typical lead time: 5-10 business days.

## Sender ID registration in Uruguay

URSEC + operator sender ID registration. Spanish supported. Registration is not a formality — an unregistered or mismatched sender ID is the most common reason otherwise-valid traffic is filtered, and the failure is usually silent rather than a hard rejection. Plan 5-10 business days for approval and register before you need the route, not during a launch.

- Lead time: 5-10 business days.
- BroadNet files sender IDs on your behalf through the URSEC-licensed operators.
- Spanish: Spanish characters supported.
- Time to production: Live in 5–15 business days from test-access request to production.

## Consent and content rules

Law 18.331 (Personal Data Protection) enforced — GDPR-aligned. Transactional messages — one-time passcodes, delivery and account alerts — are treated differently from marketing, but the distinction is decided by the content of the message rather than by how the campaign is labelled.

- URSEC sender ID: Sender IDs registered via operator route.
- Law 18.331: Uruguayan PDP Law (GDPR-aligned) enforced.
- Spanish: Spanish characters supported.

## What this means for your integration

Practically, three things decide whether traffic to Uruguay performs: a registered sender ID on a URSEC-licensed route, a consent and opt-out record you can evidence, and message content that matches the category it was registered under. BroadNet's compliance engine checks each submission against the Uruguay ruleset before it reaches the operator, so a non-compliant send is rejected back to you rather than filtered silently downstream — which is the difference between a fixable error and traffic that quietly disappears.

- Every message returns a delivery receipt (DLR); BroadNet does not publish per-country delivery percentages.
- Indicative list pricing: USD 0.03 – 0.055 per message.
- Addressable mobile base: 5M subscribers.
- Law 18.331: Uruguayan PDP Law (GDPR-aligned) enforced.
