# Messaging features in Ireland (IE1)

SMS messaging is available in Twilio's [Ireland (IE1) Region](/docs/global-infrastructure/understanding-twilio-regions) for [EU Data Residency][eu-data-residency].
This page covers the available Messaging features in the IE1 region.

> \[!IMPORTANT]

> Data Residency for SMS in the EU is currently available as a Public Beta product and the information contained in this document is subject to change. This means that some features are not yet implemented and others may be changed before the product is declared as Generally Available. Public Beta products are not covered by the Twilio Support Terms or Twilio Service Level Agreement (SLA). Learn more about [beta product support](https://help.twilio.com/articles/115002413087-Twilio-Beta-product-support).

To get started with sending SMS in IE1, see the guide: [Use the Programmable Messaging API with Twilio Regions][messaging-in-ie1].

## API-only public beta

## Message Redaction

Twilio Edition's [Message Redaction](/docs/messaging/guides/privacy-message-redaction) is supported in IE1. You can redact message bodies and end user phone numbers using:

* **Automatic redaction with message settings:** Navigate to Messaging > Settings > General Settings in the Console and enable Message Body Redaction and Phone Number Redaction.
* **Message API parameters:** Set the `contentRetention` parameter to `discard` and the `addressRetention` parameter to `obfuscate` when sending a message.

> \[!NOTE]
>
> Messaging redaction settings apply to messages in both US1 and IE1 regions.

The unredacted information is stored within the IE1 region in Twilio's production environments for up to 24 hours, and unredacted messages are stored with limited access for compliance purposes.
