Description:

SMS notifications sent by Atlassian products (e.g., Opsgenie alerts, JSM notifications) might experience poor delivery rates in Brazil. Messages are frequently delayed, silently dropped, or blocked by local carriers before reaching end users.

Brazil's telecom landscape presents specific challenges, including strict carrier-level filtering, regulatory requirements for sender registration, and the need for compliant local routing.

Suggestion:

Improve SMS routing for Brazilian mobile numbers.
