Why My SIM Card Is Not Showing Network and How to Fix It

Learn why your SIM card is not showing network and discover simple solutions to restore signal, fix SIM errors, and reconnect your phone.

Losing network on your phone can be frustrating, especially when you need to make an urgent call or use mobile data. Many smartphone users often ask, “Why is my SIM card not showing network?” This issue can happen for several reasons, from simple glitches to technical problems with your device or SIM card.

In this guide, we’ll explain the common causes of SIM network issues and share practical solutions to help you get your phone connected again.

Common Reasons Why Your SIM Card Is Not Showing Network

If your phone suddenly shows “No Service” or “Emergency Calls Only,” here are some likely causes:

Poor Signal Coverage – If you are in a remote or underground area, your SIM may not connect to the nearest tower.
SIM Card Misplacement – A loosely fitted SIM card tray can prevent your phone from detecting the SIM.
Network Outage – Sometimes, your mobile carrier may be experiencing downtime or system maintenance.
Airplane Mode – Accidentally turning on Airplane mode disables all network services.
SIM Card Damage – A scratched or worn-out SIM chip can cause network failure.
Phone Settings Error – Incorrect network settings or outdated software may block connectivity.

How to Fix SIM Card Not Showing Network

Here are step-by-step solutions you can try:

1. Restart Your Phone

The simplest fix is often a restart. Rebooting clears temporary glitches and forces your phone to reconnect to the network.

2. Check Signal Coverage

Move to an open space or near a window if you’re indoors. Poor coverage areas are a common reason for network loss.

3. Reinsert the SIM Card

Power off your phone.
Remove the SIM tray.
Clean the SIM gently with a soft cloth.
Reinsert it securely and restart your device.

4. Turn Off Airplane Mode

Make sure Airplane mode is off. On Android, swipe down from the top of the screen; on iPhone, open the Control Center.

5. Select Network Manually

Sometimes automatic selection doesn’t work. To fix:

Go to Settings > Mobile Networks > Network Operators.
Choose your carrier (e.g., MTN, Airtel, or Glo) manually.

6. Update Carrier Settings

Network providers often release updates to improve connectivity. On iPhone, go to Settings > General > About. On Android, check Settings > System Updates.

7. Reset Network Settings

If the issue persists:

On Android: Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth.
On iPhone: Settings > General > Reset > Reset Network Settings.

This clears incorrect configurations without erasing your data.

8. Replace a Faulty SIM

If your SIM is physically damaged or too old, request a replacement from your carrier’s nearest service center.

When the Problem Is With Your Carrier

Sometimes the issue isn’t your phone or SIM but your network provider. Carriers like MTN Nigeria, Airtel, and 9mobile occasionally face service disruptions. You can:

Check your carrier’s official website or social media for outage updates.
Contact customer support for troubleshooting.
Use apps like MyMTN App to manage SIM services and check for issues.

Preventing Future SIM Network Issues

To reduce the chances of your SIM card not showing network:

Keep your SIM in good condition.
Update your phone’s software regularly.
Use only official SIM trays that fit your device.
Avoid areas with known poor coverage when making important calls.

If you’ve been wondering “why my SIM card is not showing network,” the good news is that most problems have simple solutions. From reinserting your SIM card to resetting network settings, you can often fix the issue within minutes. However, if your SIM remains undetected after trying these steps, contact your carrier for a SIM replacement or phone checkup.

Don’t let network problems slow you down. Download the MyMTN App or your carrier’s official app to manage SIM services, check outages, and keep your mobile line connected anytime.
