Incident History

We are no longer experiencing SMS delivery delays to MobiFone network in Vietnam via a subset of long code numbers & alphanumeric senders. This incident has been resolved.

Some messages created between 05:30 and 05:40 UTC on Oct 28 may not be retrievable via the Messaging Logs API or visible in the Messaging Console. Message delivery was not affected. This incident has been resolved

In reference to previous incident https://status.twilio.com/incidents/2m0wy7gyl7bx, Following an amendment to Decree 4/2012 (I.24), calls made to Hungary using fixed or geographic numbers (like +36 1-9...) as a CLI are now likely to be blocked by local carriers, as of October 15, 2025. This will expand to mobile numbers (like +36 20, 30, 70...) starting June 1, 2026.

This means calls made with Transit Caller ID and Verified Caller ID will be delivered by Twilio on a best-effort basis when you're using a Hungarian CLI.

Recommended steps:

• For calls made into Hungary using Verified Caller ID or Transit Caller ID avoid using Hungarian numbers (+36 1-9… and +36 20, 30, 70...) as your CLI as the calls are likely to be blocked.
• If a Hungary CLI isn’t a priority for your use case, use a non-Hungarian CLI like your main business or international service number. If you need one, you can quickly get a United States (+1) number right in the Twilio Console to use for these calls.

If you observe abnormal failure patterns, please reach out to Twilio Support for further assistance.
