The ultimate solution to phone spam: this is how you can record calls and report them officially.

The Spanish Government implemented the measures contemplated in Order TDF/149/2025 on June 7, prohibiting companies from making calls from mobile numbers, allowing them to do so only through a specific prefix. But beyond protecting users from spam calls , the Spanish Government also aims to combat scam attempts .
Despite implementing this measure, many users continue to receive these types of calls without permission . Therefore, the Spanish Data Protection Agency, which has the power to investigate and sanction companies that insist on making spam calls, has optimized the process for reporting them.
Of course, this body can only intervene if the complaint is accompanied by evidence , so we're going to explain how to record these calls on both Android and iPhone and what steps you need to follow to report it.
How to record calls on AndroidTo record calls on Android, there's a very popular app called Call Recorder . This app lets you choose what's recorded: incoming voice, outgoing voice, or both. It also integrates with Google Drive so you can keep recordings in the cloud in case they're deleted from your phone.
There are also other alternatives to this app, such as Call Recorder - Cube ACR . This app, in addition to recording regular phone calls, also allows you to record calls from different platforms such as Telegram, Facebook, Signal, WhatsApp, Skype, Hangouts, and others.
If you prefer, you can also record conversations on Android through the "Phone" app by following these steps:
- On your Android device, open the "Phone" app.
- At the top right, tap "More options," then "Settings," then "Call recording."
- Under "Always Record," tap "Selected Numbers."
- Activate "Always record" the selected numbers.
- At the top right, tap "Add."
- Choose a contact.
- Tap "Always Record."
Apple is much more restrictive than Android when it comes to allowing call recording, and your iPhone has blocked call recording from the system, so it also doesn't allow direct audio recording of calls.
However, HD Call Recorder is an app that creates a conference call between you, the person you're calling, and the app's own recording service. When the call ends, the recording is saved to your iPhone.
As with Android, you can also do this directly from the 'Phone' app for iOS .
- Go to the "Phone" app on your iPhone.
- Make a call.
- During the call, tap the "Start Call Recording" button.
- Both call participants hear an audio notification that the call is being recorded.
- To stop recording, tap the "Stop" button or simply hang up.
- Call recordings are automatically saved to the "Call Recordings" folder in the "Notes" app.
- To view the call in the Notes app, tap "Access Saved Call."
The first thing you need to do is click this link , which will take you to the "Procedures" section and the "I receive advertising phone calls" section. Once you're logged in, you'll see that it asks for the following documentation, and you'll need to follow the procedure on the website itself.
- Identification of the entity that called you.
- Telephone number along with the company name.
- Recording of the call or other evidence to prove it.
- Choose how to file your complaint: electronically or on paper. If you prefer to file electronically, you will be asked for your digital certificate and electronic signature.
- Fill in the other fields with the requested information and continue the process.
