How Can I Block All Incoming Calls?

Yes, you can block all incoming calls with Do Not Disturb/Focus, carrier call barring, or airplane mode—each with different trade-offs.

Goal: stop your phone from ringing—fully and reliably—without breaking texts, data, or emergency access. This guide gives clear paths for iPhone, Android, and carrier features, plus a fast comparison to pick the right approach for your situation.

How Can I Block All Incoming Calls — Step-By-Step

Quick pick: if you need a zero-ring setup right now, turn on Airplane Mode and use Wi-Fi for data. For a smarter, daily-use solution, set up Focus/Do Not Disturb to allow nobody. For a carrier-level cut-off, use call barring or unconditional call forwarding (where offered).

Use Airplane Mode — Total radio off. Calls can’t reach you at all. Turn it on from the quick settings panel (iOS Control Center or Android Quick Settings). Keep Wi-Fi on if you still want messaging and apps over the internet.
Set Focus/Do Not Disturb To Allow No One (iPhone) — Go to Settings > Focus > Do Not Disturb, open People, set Allowed People Only with an empty list, and make sure repeat callers aren’t allowed. Apple’s guide shows how to silence people and apps for each Focus mode (Apple Support; iOS Do Not Disturb).
Use Modes & Do Not Disturb (Android) — Open Settings > Modes (or Sound > Do Not Disturb), then set People to allow no calls and turn off repeat callers. Google’s help page walks through the toggles (Android Support).
Turn On Carrier Call Barring (Where Available) — Many carriers support GSM barring codes that block all incoming calls on the line. On supported networks, dialing a short code with your barring PIN can block every incoming call at the network. Example codes are documented by carriers such as Vodafone AU and One NZ (Vodafone AU; One NZ).
Forward All Calls Unconditionally — If your carrier offers unconditional forwarding (CFU), forward your number to voicemail or another number so your phone never rings. See carrier pages for the exact code and format (AT&T; T-Mobile; Telstra).

Blocking All Calls On iPhone: Focus, Silence Unknown, Forwarding

Deeper fix: build a “No Calls” Focus you can toggle in one tap. This gives you silence on demand while keeping mobile data and Wi-Fi active.

Method A — Focus / Do Not Disturb With No Allowed Callers

Create or Edit A Focus — Go to Settings > Focus > Do Not Disturb.
Block People — Tap People → set to Allowed People Only and keep the list empty. Turn off Allow Repeated Calls if present (Apple Support).
Silence Apps Too — In Apps, keep the allowed list empty for a fully quiet profile.
Toggle From Control Center — Open Control Center and tap the Focus tile to switch it on fast (Apple: Turn DND On/Off).

What it does: your iPhone won’t ring or light up for calls while the Focus is on. Calls aren’t blocked at the network; they go to voicemail silently.

Method B — Silence Unknown Callers (Good For Spam Reduction)

Enable The Switch — Go to Settings > Phone > Silence Unknown Callers. Unknown numbers go straight to voicemail without ringing (Apple: Screen & Block Calls).

Note: this isn’t a full block—contacts can still ring. Pair it with Focus if you need a complete quiet profile. Media coverage also outlines options like Live Voicemail for screening (The Verge).

Method C — Forward All Calls (Carrier Feature)

Use Carrier Controls — Some carriers let you forward every call instantly so your phone never rings. See AT&T’s guide, T-Mobile’s short codes, or Telstra’s code format (AT&T; T-Mobile; Telstra).

Tip: forwarding sends callers to voicemail or another number immediately. Use this when you want full silence but keep the line reachable for messages.

Blocking Every Call On Android: Do Not Disturb, Barring, OEM Tools

Quick setup: build a mode in Settings > Modes (or Sound > Do Not Disturb) with zero allowed callers. Turn off “allow repeat callers.” Google’s help page lists the toggles and where to find them on most devices (Android Support).

Method A — Do Not Disturb With No Allowed People

Open Settings — Find Modes (or Do Not Disturb under Sound).
Block People — Under Notification filters → People, set calls to “None.” Turn off repeat callers (Android Support).
One-Tap Toggle — Add the mode as a Quick Settings tile for fast switching.

Method B — Samsung Call Barring (Network-Level, If Supported)

Open Phone App Settings — Go to Phone > Settings > Supplementary services or Call barring.
Block Incoming Calls — Turn on All incoming calls barring. You may be asked for a barring PIN set by your carrier (Samsung Support).

Note: call barring runs on the carrier network. Availability, pricing, and PIN rules vary by country and plan. Carrier help pages such as Vodafone AU and One NZ document the codes and PIN requirement (Vodafone AU; One NZ).

Method C — Unconditional Call Forwarding (CFU)

Turn On CFU — Many carriers let you forward all calls with a short code or a toggle in Phone settings. T-Mobile lists **21*number# and related codes; AT&T, Telstra, and others provide their own pages with exact steps (T-Mobile; AT&T; Telstra).

What to expect: callers are sent away immediately, so your phone won’t light up. Data and notifications still work since your radios stay on.

“Can I Carry Over Data But Block Calls?” Practical Combos

Pick by outcome: do you want complete radio silence, or do you want data to keep flowing while calls get diverted or muted? Use these mixes.

Pure Silence — Airplane Mode + Wi-Fi on. Calls can’t reach you; apps keep working over Wi-Fi.
Mute Without Cutting Data — Focus/Do Not Disturb with no allowed callers (iPhone or Android). Calls go to voicemail quietly (Apple; Google).
Network-Side Block — Carrier call barring for all incoming calls, where available. Requires barring PIN and a supported plan (Vodafone AU).
Send Every Call To Voicemail — Unconditional call forwarding to voicemail or another number; your device never rings (AT&T; T-Mobile).

Carrier-Level Controls: Call Barring And Forwarding Codes

Network tools: on many GSM networks, two features help: Call Barring (block calls at the network) and Unconditional Forwarding (send all calls elsewhere). Carriers publish their exact codes and any charges.

Call Barring (Block All Incoming Calls)

Find Your Carrier’s Page — Look up the codes and the Barring PIN. Examples: Vodafone AU, One NZ.
Turn It On — On supported carriers, the “All incoming calls” switch in your Phone settings or a short code will activate barring (Samsung documents the menu path on Galaxy phones: Samsung Support).
Turn It Off — Use the matching “unblock” code or toggle.

Unconditional Call Forwarding (Send Every Call Away)

Use The Carrier Code Or Settings — AT&T provides a step-by-step page; T-Mobile lists short codes; Telstra gives the exact **21* format (AT&T; T-Mobile; Telstra).
Forward To Voicemail Or Another Number — Choose voicemail for a silent mailbox, or a teammate/secondary line if you want a person to catch calls. Some carriers show forwarding status and let you turn it off online (AT&T portal).

Cost & coverage: call barring or forwarding may carry fees or limits depending on your plan and country. Always defer to your carrier’s current page for your line.

Smart Tweaks So Nothing Slips Through

Close the gaps: a few small switches decide whether any call can still ring during quiet time.

Turn Off Repeat Callers — On iPhone/Android DND, disable the option that lets a second call within 15 minutes ring through (Android Support).
Empty Allowed Lists — Keep the Focus/Do Not Disturb “Allowed People” and “Allowed Apps” lists empty on iPhone (Apple Support).
Use Live Voicemail Or Screens — On iPhone, Live Voicemail can transcribe silently while you decide to pick up (The Verge).
Use Carrier Apps For Spam — AT&T ActiveArmor, Verizon Call Filter, and T-Mobile Scam Shield help with spam control; voicemail blocking may require carrier features (Lifewire overview).

FAQ-Style Clarifications Without The Fluff

Will Emergency Calls Still Work?

Straight answer: Airplane Mode disables cellular calling, including emergency dialing from the line while it’s on. If you need the ability to place an emergency call at any moment, prefer Focus/Do Not Disturb with no allowed callers—or call barring/forwarding—so radios stay active. Your local regulations and carrier features apply.

Does Blocking Calls Also Block Data Or Messages?

Device-side silence: Focus/Do Not Disturb mutes calls while data and apps continue to work. Network-side tools (barring/forwarding) don’t cut data either. Airplane Mode cuts cellular voice and data, but you can re-enable Wi-Fi for apps.

What If I Want A One-Tap Quiet Switch?

iPhone: add your “No Calls” Focus to Control Center; Android: add your custom mode tile to Quick Settings (Apple; Google).
