If your phone calls keep dropping, voices break, or calls disconnect automatically, it can be extremely frustrating—especially during important conversations. This issue is common on Android phones and is often caused by network settings, signal issues, or software configuration rather than a faulty phone.
I personally faced this issue in an area where signal bars looked fine, but calls still dropped after a few minutes. After checking network mode and SIM settings, the problem was fixed without changing the phone or SIM card.
In this article, I’ll explain why phone calls drop frequently and share practical fixes that actually work.
How Call Drop Problems Usually Appear
You may notice:
- Calls disconnect suddenly
- Voice breaks before call drops
- Calls drop in specific locations
- Calls drop after a few minutes
- Internet works fine but calls fail
These symptoms help identify the real cause.
Common Reasons Phone Calls Keep Dropping
1. Weak or Fluctuating Network Signal
Signal strength may change even if bars look stable.
2. Incorrect Network Mode
Forcing 4G/5G may affect call stability.
3. VoLTE Issues
VoLTE can cause call drops if not supported properly.
4. SIM Card Problems
Old or damaged SIM cards affect call quality.
5. Software Bugs or Network Settings
Corrupted settings can interrupt calls.
Fixes That Actually Work
Method 1: Restart the Phone
This was the first fix that helped me.
Restarting:
- Refreshes network connection
- Clears temporary signal issues
- Reconnects to the nearest tower
Always try this first.
Method 2: Check Network Mode Settings
Wrong network mode causes instability.
Steps:
- Go to Settings → Network
- Set network mode to Auto (2G/3G/4G/5G)
- Avoid forcing only one network type
This improves call stability.
Method 3: Toggle Airplane Mode
This refreshes the network signal.
- Turn on Airplane mode for 30 seconds
- Turn it off
- Make a test call
This often fixes temporary tower issues.
Method 4: Disable VoLTE Temporarily
VoLTE can cause call drops in weak networks.
Steps:
- Go to Settings → SIM / Mobile network
- Turn off VoLTE
- Restart phone
- Test calls again
If calls improve, VoLTE was the cause.
Method 5: Remove and Reinsert SIM Card
This refreshes SIM connection.
What to do:
- Turn off phone
- Remove SIM card
- Clean gently
- Reinsert and restart phone
This fixes many SIM-related issues.
Method 6: Reset Network Settings
This fixes corrupted call-related settings.
Steps:
- Go to Settings → System
- Tap Reset options
- Select Reset Wi-Fi, mobile & Bluetooth
- Restart phone
This does not delete personal data.
Method 7: Check for Software Updates
Carrier and system updates fix call issues.
- Go to Settings → Software update
- Install pending updates
- Restart phone
Why Call Drops Happen in Specific Locations
This happens due to:
- Weak tower coverage
- Network congestion
- Building interference
Switching network mode often helps.
What You Should Avoid
- Using phone cases that block signal
- Ignoring SIM replacement for old SIMs
- Locking phone to one network type
- Assuming phone hardware is faulty
These delay the real fix.
FAQs
Can internet work while calls drop?
Yes, data and calls use different network paths.
Does VoLTE cause call drops?
In some areas, yes.
Should I change my SIM?
If SIM is old (4–5 years), replacement helps.
Is factory reset necessary?
Rarely—network reset is usually enough.
Final Thoughts
If your phone calls keep dropping, the issue is usually related to network mode, VoLTE, or SIM connectivity—not phone hardware.
From my experience, switching network mode to auto and disabling VoLTE fixed call drops instantly. Always try network-level fixes before changing devices.
