2. Turn Airplane Mode ON

3. Wait about 30 seconds

4. Turn Airplane Mode OFF

After a few seconds, your phone should reconnect to the network.

2. Restart Your Phone

Restarting your phone clears temporary system bugs that may interfere with network connectivity.

Steps:

1. Press and hold the Power button

2. Tap Restart or Power Off

3. Wait about 1 minute

4. Turn the phone back on

Once the device starts again, check if the signal has returned.

3. Check Network Mode Settings

If your phone is locked to an unsupported network mode, it may fail to detect available signals.

To change the network mode:

1. Open Settings

2. Go to Network & Internet

3. Tap Mobile Network

4. Select Preferred Network Type

5. Choose LTE / 4G / 3G (Auto)

Avoid forcing the phone to use only one network type unless recommended by your carrier.

4. Reset Network Settings

If network settings become corrupted, resetting them can restore normal connectivity.

Steps:

1. Open Settings

2. Tap System

3. Select Reset Options

4. Tap Reset Wi-Fi, Mobile & Bluetooth

After resetting, restart your phone and reconnect to the network.

Note:

This reset will not delete your photos, apps, or personal files, but it will remove saved WiFi networks and Bluetooth connections.

5. Remove and Reinsert the SIM Card

A SIM card that is slightly misaligned can prevent proper network detection.

Try reseating the SIM card:

1. Turn off your phone

2. Remove the SIM card tray

3. Take out the SIM card

4. Clean it gently using a dry cloth

5. Place it back correctly

6. Insert the tray and turn the phone on

After the phone restarts, check if the network signal appears. In some cases, this problem may occur even when the signal appears normal, but the phone cannot properly register with the network. This can result in a “No Service” or “Emergency Calls Only” message

6. Check for System Updates

Outdated Android versions sometimes contain network-related bugs.

Updating your system software may fix compatibility problems.

Steps:

1. Open Settings

2. Tap System

3. Select Software Update

7. Try Manual Network Selection

Sometimes your phone fails to automatically detect the correct carrier network.

Steps:

Open Settings
Tap Mobile Network
Select Network Operators
Disable Automatic selection
Manually choose your carrier

This forces the phone to reconnect directly to the available network. If your mobile data is connected but still not working, you can also read our guide on mobile data connected but no internet.

When to Contact Your Mobile Carrier

If none of the solutions above work, the problem may be related to your mobile carrier rather than the phone itself.

Possible carrier-related issues include:

• Network outage in your area

• SIM card activation or provisioning errors

• Account-related restrictions

• Carrier-side network maintenance

In this case, contact your carrier’s customer support for assistance. If your phone connects to WiFi but still has no internet access, check our guide on Android connected to WiFi but no internet.

Frequently Asked Questions (FAQ)

Why does my phone say No Service even with a working SIM card?

This usually happens when the phone cannot connect to nearby network towers due to incorrect settings, software bugs, or temporary signal issues.

Can a software update cause No Service problems?

Yes. Sometimes system updates change network configurations, which may temporarily affect signal detection.

Will resetting network settings delete my data?

No. Resetting network settings only removes WiFi passwords, mobile network configurations, and Bluetooth connections. Your personal files remain safe.

How do I know if the issue is from my carrier?

If your SIM card works normally in another phone but your device still shows No Service, the issue is likely related to the phone settings or software.

Why does my phone say “Emergency Calls Only”?

This usually happens when your phone cannot register with your carrier network, even though the SIM card is detected. It may be caused by signal issues or incorrect network settings.

Network problems can sometimes affect other apps as well. If you experience messaging problems due to unstable connectivity, you may also want to read our guide on WhatsApp Messages Not Sending But Internet Works.

If your phone shows No Service even though the SIM card works, the problem is usually related to network settings, temporary glitches, or software issues.

Simple solutions such as toggling Airplane Mode, restarting the device, resetting network settings, or reinserting the SIM card can often restore the connection quickly.

If the problem persists after trying all troubleshooting steps, contacting your mobile carrier is the best next step.
