FAQ
TL;DR: 9 checks and “Contact your operator” summarize the fix: this FAQ helps Android users stop phones rejecting all incoming calls by checking call blocking, forwarding, Do Not Disturb, aeroplane mode, rebooting, updating software, testing the SIM, and escalating to the operator. [#20531432]
Why it matters: A phone that rejects every incoming call can miss urgent calls even when the handset still appears usable.

Key insight: Check phone-side settings first, then isolate the SIM. If the same SIM fails in another phone, escalate the issue to the mobile operator.
Quick Facts
- The thread gives 9 practical checks: incoming-call blocking, forwarding, contact rules, voicemail forwarding, Do Not Disturb, aeroplane mode, reboot, software update, and SIM/operator testing. [#20531432]
- The Android path named in the thread is Phone settings → Applications and notifications → Telephone/Calls, although wording can differ by phone model. [#20531432]
- The call-forwarding check has 2 valid outcomes: forwarding disabled, or forwarding set to the correct number. [#20531432]
- The SIM test uses 2 phones: place the same SIM card in another handset and see whether incoming calls still fail. [#20531432]
- The forum post was published on 2023-04-08 at 23:08:49 +02:00 and recommends contacting the operator if phone-side checks do not solve the fault. [#20531432]
How do I fix a phone that rejects all incoming calls?
Start with 3 phone-side checks, then isolate the SIM.
- Turn off Block all incoming calls, Do Not Disturb, and aeroplane mode.
- Check call forwarding and selected-number blocking in the phonebook.
- Reboot, update software, test the SIM in another phone, then contact the operator. The thread lists 9 checks in total. [#20531432]
Where can I find the “Block all incoming calls” setting on an Android phone?
Look under Phone settings → Applications and notifications → Telephone/Calls. The exact label can differ by phone model, but the target setting is Block all incoming calls. It should be turned off when all incoming calls are rejected. This is the first setting named in the 2023 thread.
[#20531432]
How do I check whether call forwarding is causing my phone to reject calls?
Open Phone settings → Call forwarding and verify 2 things: forwarding is disabled, or it points to the correct number. If forwarding points elsewhere, incoming calls can skip your handset. Also check whether voicemail forwarding is active for selected contacts. The thread lists call forwarding as the second major check.
[#20531432]
What is call forwarding and how does it affect incoming phone calls?
Call forwarding redirects incoming calls to another destination instead of the current phone.
"Call forwarding" is a call-handling service that sends incoming calls to another number or voicemail, depending on settings, so the original phone may not ring when forwarding is enabled or misconfigured. Check 1 forwarding menu before replacing hardware.
[#20531432]
What is Do Not Disturb mode and why can it stop incoming calls from ringing?
Disable Do Not Disturb because it can suppress incoming-call alerts.
"Do Not Disturb" is a phone mode that limits notifications and ringing, using user settings to silence interruptions while the phone remains powered on and otherwise available. The thread lists it as 1 separate setting to turn off during troubleshooting.
[#20531432]
How does aeroplane mode affect calls, mobile signal, and SIM card access?
Turn off aeroplane mode because it can prevent normal mobile network access.
"Aeroplane mode" is a device mode that disables wireless radio functions, including mobile-network communication, so calls may not reach the SIM while the mode is active. The thread names it as 1 required check before SIM replacement.
[#20531432]
How do I disable call blocking for specific contacts in my phonebook?
Open the phonebook contact settings and remove blocking or forwarding rules for selected numbers. The thread separates contact-level settings from global incoming-call settings. That means 1 blocked contact can fail while others still ring. Also check whether voicemail forwarding is enabled for that contact.
[#20531432]
Why does my phone send callers straight to voicemail instead of ringing?
Voicemail forwarding can send callers away before the phone rings. Check forwarding for all calls and for selected numbers in the phonebook. The thread specifically asks whether voicemail forwarding is active. One edge case is contact-only forwarding, where just 1 caller reaches voicemail while other callers work.
[#20531432]
What should I check first when incoming calls fail but outgoing calls still work?
Check Block all incoming calls first, then check call forwarding. The thread places incoming-call settings at the top of the list. On Android, the cited path is Phone settings → Applications and notifications → Telephone/Calls. After that, confirm call forwarding is disabled or set to the correct number.
[#20531432]
How can I test whether the problem is caused by my SIM card or by the phone?
Put the same SIM card into another phone and test incoming calls. If the problem continues in the second handset, the thread points to a SIM card problem or operator restriction/service. If the second phone receives calls normally, focus on the original phone settings, reboot, and software update. This test needs 1 extra phone.
[#20531432]
What should I ask my mobile operator when my phone rejects every incoming call?
Ask the operator whether restrictions or services on your line block incoming calls. Report that you already checked call blocking, forwarding, Do Not Disturb, aeroplane mode, reboot, update, and the SIM in another phone. The thread’s final escalation step is: “Contact your operator and report the problem.”
[#20531432]
Call blocking vs call forwarding — which setting is more likely to make incoming calls fail?
Both can make incoming calls fail, but they fail differently. Blocking rejects calls; forwarding sends calls to another number or voicemail. The thread lists both as separate checks, with global blocking under Telephone/Calls and forwarding under Call forwarding. Check both settings before assuming a SIM or operator fault.
[#20531432]
How do I update my phone software to fix calling problems?
Use the phone’s software update option after checking call settings. The thread recommends trying a software update as 1 troubleshooting step after rebooting. It does not name a brand-specific menu, so use the update path provided by your phone model. Update only after disabling blocking, forwarding, Do Not Disturb, and aeroplane mode.
[#20531432]
Why can restarting a phone sometimes fix rejected incoming calls?
Restarting can clear a temporary phone-side fault before deeper testing. The thread lists rebooting as 1 standalone troubleshooting action. Use it after checking call-blocking, call-forwarding, Do Not Disturb, and aeroplane mode. If calls still fail after reboot and update, test the SIM in another phone.
[#20531432]
What operator restrictions or mobile services can prevent incoming calls from reaching my phone?
Operator-side restrictions or services can stop incoming calls even when phone settings look correct. The thread does not name specific services, but it flags operator restrictions/services after the SIM test. If the same SIM fails in another phone, report the problem to the operator and ask them to check line-level incoming-call handling.
