Let's go step by step to troubleshoot this:

🔧 Step-by-Step Troubleshooting for "No Service" + Wi-Fi Calling Issue

✅ 1. Confirm Wi-Fi Calling is Still Active

Go to: Settings → Connections → Wi-Fi Calling

Make sure it’s turned ON

Set Preference to Wi-Fi, not Cellular

Restart your phone after confirming

✅ 2. Check SIM & Mobile Network Status

Go to: Settings → Connections → Mobile Networks

Check if the correct SIM is selected for calls

Tap Network Operators → Search networks manually

Select your correct carrier

If it says "Unable to connect", there's an issue with the SIM or service

Also:

Try the SIM in another phone. If it still shows “No Service,” it’s a SIM or carrier issue.

✅ 3. Check for Airplane Mode / Network Reset

Make sure Airplane Mode is OFF

Try turning Airplane Mode ON → wait 10 seconds → turn OFF again

If nothing works, do a network reset:

Settings → General Management → Reset → Reset network settings

✅ 4. Update Software

Go to: Settings → Software Update → Download and Install

An outdated software version may disrupt network or Wi-Fi calling.

✅ 5. Clear Cache Partition (Does NOT delete data)

Power off your phone

Hold Power + Volume Up until the Samsung logo appears

Use volume keys to navigate to Wipe Cache Partition

Confirm with Power button

Reboot

This helps if software glitches are causing network issues.

✅ 6. Contact Carrier Support

If:

Wi-Fi is working

SIM is detected but no network at all

Worked before and suddenly stopped

Then it’s likely a carrier-side issue, such as:

SIM deactivated or suspended

VoWiFi profile removed

Network maintenance in your area

📞 Contact your mobile operator and ask:

“Is my SIM active and provisioned for Wi-Fi Calling and VoLTE?”

✅ 7. Test With Another SIM

Try inserting a different SIM (from the same or another carrier). If it shows service:

Your SIM is likely faulty

Or carrier settings are messed up

🛠️ Optional: Use Samsung Members App for Diagnostics

Open Samsung Members → Tap Get Help → Diagnostics

Run tests for SIM, Network, and Wi-Fi Calling

It might even give a suggestion or error code

🔚 If All Else Fails

If you’ve done all of the above and it still doesn’t work:

Backup your data and try a factory reset (as a last resort)

Visit a Samsung Service Center or your carrier’s support store
