# SMS Subscribers

In this step, you review your subscriber setup. SMS Subscribers is an overview page with two sub-pages:

- **Subscriber Base**
- **Unsubscription Management**

The page reflects the choice you made in [SMS Consent Settings](/v1/docs/new-sms-consent-settings). The button reads **Check Subscriber Analytics** when your consent type is defined, and **Go To SMS Consent Settings** when it is not.

> [!NOTE]
> Refer to [Use Phone Numbers as Identifiers for SMS](/v1/docs/use-phone-numbers-as-identifiers-for-sms) for details on the phone number format. Refer to [Manage SMS Global Unsubscribe](/v1/docs/manage-sms-global-unsubscribe) for further information about the **Unsubscription Management**.

## Subscriber Base

The Subscriber Base page lets you choose how your subscriber data will be collected.

To upload subscribers, refer to [Subscriber Collection](/v1/docs/subscriber-collection), and refer to [SMS: CSV Upload via Saved Segments](/v1/docs/sms-csv-upload-via-saved-segments) and [SMS: Lead Collection Templates](/v1/docs/sms-lead-collection-templates) for numbers you have already collected.

For Türkiye, this page includes a required **IYS Integration Confirmation** section. You will enter your **IYS Code** later on the [Business Information](/v1/docs/new-sms-business-information) page.

To send SMS campaigns in Türkiye, you must first integrate with IYS, Türkiye’s official consent and unsubscription management system. After completing **IYS integration**, **confirm** that it is properly configured for SMS sending in Türkiye. Without this integration, your campaigns might not function as expected.
