Fix iPhone Not Receiving Calls: Steps to Try

If your iPhone is not receiving calls, first check Airplane Mode, cellular signal, Focus settings, and call forwarding, then restart the phone and test again. If the problem continues, determine whether calls fail for every caller or only certain people; that distinction helps narrow the cause to a setting, contact, carrier, or device issue.

1. Check signal and basic call settings

Start with the simplest causes. Look at the status bar for cellular signal and confirm that Airplane Mode is off: open Control Center and tap the airplane icon if it is enabled. You can also check Settings > Airplane Mode. If you are in a basement, elevator, rural area, or building with poor reception, move somewhere with a stronger signal and ask someone to call again.

1. Turn Airplane Mode on for about five seconds, then turn it off. This reconnects the iPhone to the cellular network.
2. Check that your cellular line is enabled under Settings > Cellular (the menu may be called Mobile Service in some regions). If you use multiple lines, verify the line you expect to receive calls on is active.
3. Restart the iPhone. A restart can clear a temporary software or network connection problem.
4. Test with more than one caller, and note whether the call appears in Recents, goes straight to voicemail, or produces no visible alert.

One missed ring does not necessarily mean the phone failed to receive the call. A caller may have hung up quickly, or the phone may have been out of coverage. Repeated tests in a place with reliable signal give more useful evidence.

2. Turn off Focus and check blocked callers

Focus modes, including Do Not Disturb, can silence incoming calls or suppress their notifications. Open Control Center and see whether a Focus is active. Tap it to turn it off, or go to Settings > Focus to review its schedule and allowed people. A Focus mode usually affects whether a call alerts you; it does not by itself prove that the cellular network failed to deliver the call.

If only one person cannot reach you, check whether their number is blocked. Open Settings > Apps > Phone > Blocked Contacts on current iOS versions; on some versions, Phone settings may appear directly under Settings > Phone. Remove the number if it was blocked accidentally. Also inspect the contact card for duplicate or outdated numbers.

Silence Unknown Callers can send calls from numbers not saved in Contacts to voicemail rather than ringing normally. Find it in the Phone settings and switch it off temporarily if you are expecting a call from an unfamiliar number. Menu locations can vary slightly by iOS version, so use the Settings search field for “Silence Unknown Callers” if needed.

3. Review call forwarding and related features

Call forwarding can route calls away from your iPhone. Check Settings > Apps > Phone > Call Forwarding, or search Settings for “Call Forwarding.” If it is on and you did not intend to forward calls, turn it off. Availability and the exact options depend on the carrier and cellular plan.

Also consider whether another device or service is involved. Calls may ring on devices linked through Apple’s calling features, or a carrier voicemail or call-management feature may affect what you see. If calls reach voicemail immediately despite good signal and forwarding being off, ask your carrier whether a network-level setting is routing or blocking calls.

Do not assume that a Wi-Fi connection guarantees cellular calls will work. Wi-Fi Calling is a carrier-supported feature that can help in weak cellular coverage, but it must be available for your line and configured. Check Settings > Cellular or Mobile Service for Wi-Fi Calling. If it is already enabled and the issue occurs only on Wi-Fi, test with Wi-Fi off and cellular signal available.

4. Check for carrier, SIM, or eSIM problems

If the iPhone shows “SOS,” “No Service,” or “Searching,” or if calls fail in multiple locations, the issue may be cellular service rather than an alert setting. Confirm that your account and plan are active with the carrier, and check whether there is a local outage. A carrier can also confirm whether the line is provisioned correctly for voice service.

• Open Settings > General > About and wait briefly. If a carrier settings update is available, iOS may show a prompt.
• For a physical SIM, make sure it is seated correctly. If it appears damaged or the phone does not recognize it, contact the carrier before replacing it.
• For an eSIM or dual-SIM setup, verify the relevant line is turned on under Cellular or Mobile Service. Avoid deleting an eSIM as a troubleshooting shortcut; reactivation may require help from the carrier.
• Check for an iOS update under Settings > General > Software Update, especially if the problem began after a software change.

Carrier names and menu wording differ by region, and some account or network settings can only be checked by the carrier. If your line has no service, repeatedly changing unrelated iPhone settings is unlikely to restore an outage or an inactive account.

5. Reset network settings only if needed

If the issue persists after the checks above, resetting network settings is a reasonable later step. On current iOS versions, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Read the confirmation carefully before proceeding.

This reset removes saved Wi-Fi networks and passwords and resets certain cellular, VPN, and network preferences. It does not erase photos, messages, or apps, but you will need to reconnect to Wi-Fi and may need to restore network configurations. Do not choose Erase All Content and Settings for a call-reception problem unless you have a separate reason and a verified backup.

If a network reset makes no difference, contact the carrier and then Apple Support or an authorized service provider as appropriate. Tell them when the issue began, your location, whether all callers are affected, what the status bar shows, and which steps you tried. That information helps distinguish a line or coverage problem from an iPhone fault.

6. Common symptoms and what they suggest

• Only unknown callers go to voicemail: Check Silence Unknown Callers, Focus settings, and any call-filtering service.
• One contact cannot get through: Check blocked contacts, the saved number, and whether the caller is dialing the correct number.
• Every call goes to voicemail: Check signal, forwarding, active cellular lines, and carrier service. Then test again after restarting.
• The phone rings but you do not hear it: This is more likely an alert-volume, sound, or connected-audio issue than failure to receive calls. Check the Ring/Silent control where applicable, ringtone settings, and connected Bluetooth devices.
• Calls fail only in one place: Coverage or local network conditions are likely factors. Test elsewhere or ask the carrier about coverage and outages.

Changing the ringtone volume will not fix a call that never reaches the phone, while restoring the whole iPhone is rarely the best first move. Identify whether the call is absent, silenced, forwarded, or sent to voicemail before choosing the next step.

Frequently Asked Questions

Why does my iPhone send calls straight to voicemail?
Weak or absent cellular service, an inactive line, call forwarding, Focus or call-filtering settings, and carrier-side issues can all contribute. Check signal and settings, then contact your carrier if it happens consistently.

Why can’t I receive calls from one person?
Check whether the number is blocked, saved incorrectly, or affected by a call-filtering setting. Ask the person to call from another number to help determine whether the issue is tied to their number.

Will resetting network settings delete my data?
It does not erase personal content such as photos and messages, but it removes saved Wi-Fi networks and passwords and resets some network preferences. You will need to reconnect to Wi-Fi afterward.

Can Do Not Disturb stop calls from coming through?
Focus settings can silence or limit call alerts according to their configuration. Turn Focus off for a test, then review which people and calls are allowed.

Should I remove my SIM or erase my iPhone?
Do not erase the phone as an early troubleshooting step. Check settings and service first; ask the carrier about a SIM or eSIM, and use a full erase only when specifically warranted and after confirming a backup.
