How to Set Up WiFi Calling on iPhone and iPad

WiFi Calling on iPhone: Step-by-Step

If you want to set up iPhone for WiFi calling, follow these exact steps. Wi‑Fi calling routes regular phone calls over a Wi‑Fi network when cellular coverage is weak. Your phone number stays the same and most carriers treat these calls like normal calls on your plan.

1. Check carrier support and iOS version

• Confirm your carrier supports Wi‑Fi Calling. Most major carriers do, but some regional or international carriers may not.
• Update to the latest iOS: Settings > General > Software Update.

2. Enable Wi‑Fi Calling

• Open Settings > Phone > Wi‑Fi Calling.
• Toggle on Wi‑Fi Calling on This iPhone.
• You’ll be asked to confirm an emergency address for 911. Enter a physical address where you can be reached over Wi‑Fi.

3. Verify your phone number and registration

• The phone may register Wi‑Fi calling with your carrier. This can take a few minutes.
• You should see “Wi‑Fi” next to your carrier name in the status bar when a Wi‑Fi call is active.

4. Test a call

• Make a short test call to a friend or voicemail.
• Observe the call quality and check that your incoming call ringtone behaves normally.

5. Optional: Allow Calls on Other Devices

• To let your iPad or Mac place and receive calls using your iPhone’s line, go to Settings > Phone > Calls on Other Devices and toggle on Allow Calls on Other Devices. Then select the devices you want to use.

Notes and practical tips

• Emergency services: Wi‑Fi calling uses the emergency address you set. If you move, update that address immediately.
• Connection quality: Wi‑Fi calling needs a stable connection. A home router on 2.4 GHz or 5 GHz with good upload speed (≥ 0.5 Mbps) works best.
• Roaming: Some carriers restrict Wi‑Fi calling while roaming. See the international section below.

If you want to use your iPhone’s Wi‑Fi calling functionality to let other devices sign in, the Settings > Phone > Calls on Other Devices options make the setup straightforward. For alternatives that call real phone numbers directly from Wi‑Fi (without relying on your carrier), check apps that explain VoIP phone services in our guide to VoIP phone services explained.

Setting Up WiFi Calling on iPad

Apple doesn’t implement a full carrier Wi‑Fi Calling feature independently on all iPad models the way it does on iPhone. How you enable calling from iPad over Wi‑Fi depends on what you want to do: use your iPhone’s cellular line from your iPad, or call phone numbers directly from the iPad without an iPhone.

A. Use your iPhone’s line on iPad (Calls on Other Devices) This is the easiest way to get calling from iPad Wi‑Fi:

1. On your iPhone: Settings > Phone > Calls on Other Devices > Allow Calls on Other Devices. Turn on the devices listed.
2. On your iPad: Settings > FaceTime > Calls from iPhone (or Settings > FaceTime and enable Calls from iPhone). Sign in with the same Apple ID on both devices.
3. Make or receive calls on the iPad using the Phone app or the FaceTime audio option.

This method requires the iPhone to be powered on and connected to the same Wi‑Fi network or to be reachable via the same Apple ID. It effectively uses the iPhone’s telephony service; the iPad itself does not independently register with your carrier.

B. Call direct from iPad without iPhone (VoIP apps) If you want to make Wi‑Fi calls on iPad without relying on an iPhone — for example, an iPad Air, iPad mini, or iPad Pro without cellular — use a VoIP app that dials regular phone numbers. With these apps you can:

• Call landlines and mobiles worldwide over Wi‑Fi.
• Buy credit packs (prepaid) and pay per-second, usually without connection fees.
• Avoid needing a separate carrier plan or cellular data on the iPad.

How to set up a VoIP app on iPad

1. Download the app from the App Store. Search for terms like “call phone numbers” or “international calling.”
2. Allow microphone access.
3. Purchase a small credit pack if required. Many apps offer a free first minute to test.
4. Dial the phone number and call.

If you want an example, Telvio is an app that calls real phone numbers in 200+ countries over Wi‑Fi, uses per‑second billing, and provides credit packs starting at $1.99. For more context on VoIP vs. traditional calling, see our guide to VoIP phone services explained and how to make international calls in our international calling guide.

C. Special cases: iPad Air, iPad mini, iPad Pro and iPads with no cellular

• Wi‑fi calling on iPad Air / mini / Pro: The procedure is the same as above. If the iPad has no cellular, native carrier Wi‑Fi calling is not available; you must use Calls on Other Devices or a VoIP app.
• iPad with cellular: If your iPad has its own cellular plan, you may be able to use the carrier’s Wi‑Fi calling if the carrier supports it on iPad — check with your carrier. In many cases, the iPhone remains the primary device for true carrier Wi‑Fi calling.

Apple Watch WiFi Calling Features

Apple Watch supports Wi‑Fi calling in several scenarios. Here’s what you should know and how to enable it.

What Apple Watch can do

• Use Wi‑Fi networks to make and receive calls when your iPhone is not nearby, if your Apple Watch supports Wi‑Fi and your carrier allows it.
• Make calls over a known Wi‑Fi network even if the iPhone is turned off, as long as the watch has been set up for Wi‑Fi calling.

Requirements

• Apple Watch (Series 3 and later include better Wi‑Fi support) with the latest watchOS.
• iPhone with the latest iOS paired to the watch.
• Wi‑Fi calling enabled on the iPhone and supported by your carrier.
• Same Apple ID signed into iPhone and Apple Watch.

How to enable Apple Watch Wi‑Fi Calling

1. Update both devices to the latest software.
2. On iPhone: Settings > Phone > Wi‑Fi Calling > toggle on Wi‑Fi Calling on This iPhone and follow any prompts.
3. Open the Watch app on iPhone: My Watch > Phone. If your carrier supports Wi‑Fi calling for the watch, you’ll see options to enable it here; follow the prompts.
4. On Apple Watch, connect to a known Wi‑Fi network (Settings > Wi‑Fi) and verify the Wi‑Fi icon appears in Control Center.
5. Place a test call from the watch: open Phone on the watch and dial.

How it works in practice

• If your iPhone is off but your watch is on Wi‑Fi, outgoing and incoming calls can route through Wi‑Fi calling.
• Call quality depends heavily on the Wi‑Fi network’s upload capacity and latency.
• Emergency calls may use the address registered with your carrier; verify this address when setting up Wi‑Fi calling.

If you run into limitations — for example, your watch won’t place Wi‑Fi calls while abroad — a dedicated VoIP app on an iPhone, iPad, or Android device offers a predictable alternative for calling regular phone numbers over Wi‑Fi.

International WiFi Calling Tips

Using Wi‑Fi calling abroad is convenient, but you should check a few important considerations to avoid unexpected charges, failed calls, or emergency service issues.

Carrier policies and roaming

• Some carriers allow Wi‑Fi calling only while you’re in your home country. Other carriers permit Wi‑Fi calling while abroad but might charge roaming fees.
• Confirm with your carrier whether Wi‑Fi calling works in the country you’re visiting.

Emergency calling limitations

• Emergency services vary by country. Carriers require an emergency address for Wi‑Fi calling in your home country; when abroad, emergency dispatch may not route correctly over Wi‑Fi.
• If you plan to rely on Wi‑Fi calling for emergencies while traveling, call your carrier to confirm procedures.

Alternatives for reliable international calling

• Use a VoIP app that calls real phone numbers over Wi‑Fi. These apps typically let you buy credit packs and dial international numbers at low rates. For example, Telvio charges from $0.02/min to the US and $0.08/min to India, with per‑second billing and credits that don’t expire.
• Use local SIM + Wi‑Fi where necessary, or rent a local hotspot for better voice quality.

Practical checklist before you travel

• Update iOS and carrier settings.
• Test Wi‑Fi calling at home and confirm emergency address.
• Install a VoIP app as a backup and add some credit. Many apps provide a free test minute on first install.
• Know local regulations: some countries block VoIP or Wi‑Fi calls to international numbers.

Troubleshooting WiFi Call Connectivity

If Wi‑Fi calls drop, have poor audio, or won’t connect, try these focused fixes in this order.

1. Confirm basics

• Is Wi‑Fi connected and stable? Try a speed test: upload speed matters for calls.
• Is Bluetooth creating interference? Toggle Bluetooth off and test again.

2. Toggle settings

• Turn Wi‑Fi Calling off and on: Settings > Phone > Wi‑Fi Calling.
• Restart your iPhone and any device you want to call from (iPad, Apple Watch).

3. Update software

• Update iOS/watchOS to the latest available versions.
• Update carrier settings: Settings > General > About and accept any carrier updates.

4. Reset network settings

• Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Note: this removes saved Wi‑Fi passwords.

5. Router considerations

• Reboot the router.
• Move closer to the router or switch frequency bands (5 GHz often performs better for low-latency).
• Ensure Quality of Service (QoS) isn’t limiting voice traffic and that SIP ALG or other voice filters aren’t enabled if you use an on-premises VoIP adapter.

6. Check carrier account and region restrictions

• Verify your account is in good standing and that Wi‑Fi calling is enabled by your carrier.
• If abroad, confirm the carrier allows Wi‑Fi calls from your current location.

7. Third‑party app issues

• If using a VoIP app (calling from iPad Wi‑Fi via an app), make sure the app has microphone permission and background app refresh if needed.
• For poor audio with a VoIP app, switch to a different server region in the app (if the app supports it) or test on another network.

8. When all else fails

• Contact carrier support with logs if your carrier controls Wi‑Fi calling.
• For VoIP apps, reach out to the app’s support, provide timestamps and network diagnostics.

A quick checklist to keep on hand:

• Update OS, enable Wi‑Fi calling, set emergency address.
• Test calls at home before travel.
• Install a VoIP backup app and add a small credit pack.
• Keep router firmware up to date.
