## How to Block Spam Calls on iPhone (No App Required)

Below is the **iPhone call blocking settings guide** that eliminates unwanted calls and texts. Grab your phone and work through each toggle – it’s fast, free, and stays entirely within iOS.

### 1. Open Settings → Phone  
Launch **Settings**, scroll down, and tap **Phone**. This hub holds every call‑related option.

### 2. Tap “Call Blocking & Identification”  
Inside the Phone menu, select **Call Blocking & Identification**. You’ll see any numbers you’ve already blocked and a few toggle switches.

### 3. Add Numbers to “Blocked Contacts”  
- Tap **Add New** to type a spam number, or choose a recent call from your log.  
- Once added, the number is sent straight to voicemail.  

> **Pro tip:** Keep a short list of the worst spam prefixes and add them here regularly. It’s a tiny habit that blocks dozens of calls.

### 4. Enable “Silence Unknown Callers”  
Toggle **Silence Unknown Callers** on. This is the core **how to block unknown numbers on iPhone** setting: calls from numbers not in your contacts, recent calls, or Siri suggestions go directly to voicemail while still appearing in your missed‑call log.

### 5. Filter Unknown Text Senders  
Open **Settings → Messages** and switch on **Filter Unknown Senders**. Messages from unfamiliar numbers are moved to a separate tab, keeping your main inbox clean.

### 6. (Optional) Use “Do Not Disturb” for Unknown Callers  
- Go to **Settings → Focus → Do Not Disturb**.  
- Tap **People → Calls From** and choose **All Contacts**.  

This ensures only saved contacts can ring through, perfect for meetings or quiet moments.

### 7. Periodically Review Recent Calls  
Spammers sometimes spoof saved contacts. Scan your recent calls list; if a number looks suspicious, tap the **i** icon and select **Block this Caller**. A quick habit that adds an extra safety net.

### 8. Visual Walkthrough (Screenshots)
