Why Phone Shows Missed Call But Never Rings – Real Reason Explained
Sometimes we wait for an important phone call. It could be from your boss, from an interview, or maybe a family member. You keep checking your phone again and again, making sure:
it’s not on silent
Do Not Disturb is off
ringtone volume is full
But suddenly you see a Missed Call on the screen…
And the most shocking part — the phone never rang at all.
This problem happens with many people, and most of us think our phone is faulty or the network is bad.
But the real reason is a bit complicated… and also surprising.
How the Mobile Call System Works (Easy Explanation)
When someone calls you, their phone sends a request to your mobile network.
Here’s what happens:
The caller dials your number
Telecom network sends the call request
Your phone receives the signal
Your phone starts ringing
This all happens within seconds.
But today’s call system uses advanced technology like 4G and 5G, and because of this, many times the phone doesn’t get the call signal properly.
And that’s when you get a missed call without any ringing.
VoLTE and VoNR – The Hidden Reason
Today’s mobile calls run on VoLTE (Voice over LTE) or VoNR (Voice over 5G).
If VoLTE is turned OFF on your phone, then your phone tries to switch to old 3G network to receive the call.
But here is the big problem:
3G is shut down in many countries
In India also, 3G has almost disappeared
So when your phone tries to jump to 3G and fails, the call never reaches your phone.
Result → No ringing + Missed call appears.
IMS Registration Failure – A Very Common Issue
Your phone always stays “registered” on the network using IMS (IP Multimedia Subsystem).
But sometimes IMS fails because of:
software glitches
temporary network drops
If IMS is not registered properly, your phone will not receive any incoming call signals.
So the call actually comes — but your phone doesn’t know about it.
This is why the phone shows a missed call without ringing.
5G to 4G Handover Problem
Most phones use 5G only for data.
But voice calls still run on 4G.
So when someone calls you, your phone needs to switch:
5G → 4G
If this switching is slow or fails, the call cannot connect to your phone.
Result:
call reaches the network
phone fails to switch to 4G
phone doesn’t ring
missed call shows up
This is a very common issue for 5G users.
Dead Zones – Signal Looks Fine but Calls Don’t Come
Many houses, offices, or rooms have places where network bars appear, but call signals are still weak.
These are called dead zones.
In such spots:
signals are unstable
data works sometimes, calls don’t
call signal reaches too late
Your phone gets confused, and the call never rings.
Apps Can Also Block Your Calls
Modern phones have aggressive battery saver systems.
Sometimes they put background apps to sleep, including the Phone App itself.
If the Phone App is restricted:
incoming call comes
app doesn’t wake up
phone doesn’t ring
This is a very real issue on many Android phones.
Other apps that may block calls:
call recording appscall blocker apps
How to Fix This Problem – Simple Solutions
If your phone shows missed calls without ringing, try these fixes:
1. Turn ON VoLTE / VoNR
Settings → Mobile Network → Enable VoLTE/VoNR
2. Restart the Phone
This refreshes network registration.
3. Airplane Mode On/Off
A quick way to reset network signals.
4. Disable Battery Optimization for Phone App
Settings → Battery → Phone App → “Don’t optimize”
5. Contact Your Carrier
Sometimes VoLTE is not activated on your number.
Can This Always Be Fixed?
Honestly — no.
Sometimes the issue is completely from the network side, and you cannot do anything.
But yes, the good thing is…
If you miss an important call, you always have a valid excuse:
“Yaar phone ring hi nahi hua… network issue hoga.”
Funny but true.
Conclusion – Now You Know the Real Reason
When your phone shows a missed call without ringing, the real reasons can be:
VoLTE turned off
IMS registration failure
5G to 4Gswitching problem
network dead zones
battery saver blocking apps
call-blocking apps
This issue is annoying but common.
And with these simple steps, you can fix it most of the time.
