Last updated: 23 October 2026

These terms describe Stop 400, an iPhone app provided by TRISIMIO SL.

What Stop 400 does

The app lets you choose to block Spanish numbers from +34 400 000 000 to +34 400 999 999 using the iOS call-blocking extension. The full range may include legitimate commercial calls. Stop 400 does not verify or classify individual calls as spam or fraud.

Activation and limits

To use the filter, enable the extension in iOS Settings and allow the system to load the list. Status and operation depend on iOS and your device configuration. Stop 400 does not affect WhatsApp, FaceTime or SMS and does not control other device or carrier filters. The app does not promise to prevent all unwanted, commercial or fraudulent calls.

Purchase

The unlock is a non-consumable in-app purchase managed by Apple. The purchase screen displays the price and terms for your storefront. Billing, refund or purchase-management requests follow Apple’s processes.

Using the app

Use the app in accordance with applicable laws and Apple’s terms. Setup is optional, and you can disable the extension in iOS Settings. Removing the app and disabling the extension are separate actions; check the status in Settings.
