Why is my phone showing only one SIM card?

Modern smartphones are complex tools that depend on a combination of hardware, software, and network services to function properly. A simple glitch in one of these areas can temporarily disrupt your ability to make calls. Sometimes the issue lies with your carrier, while in other cases it may be something as simple as incorrect settings, a weak signal, or even a small software bug. Understanding the possible causes is the first step toward resolving the problem effectively.

This guide will provide a comprehensive look at the reasons why your phone may not be making calls and will walk you through practical solutions. From checking your network and SIM card to troubleshooting operating system glitches and carrier-related issues, we will cover each step in detail. By the end, you will have a clear roadmap for restoring your phone’s ability to make calls, saving you time and reducing unnecessary stress.

Common Reasons Why Phones Calls not Going Through

1. Weak or No Network Signal

The most common reason your phone may not make calls is poor signal strength. If you are in an area with limited coverage—such as a rural location, a basement, or an area with thick walls—the phone may struggle to connect to the network. Signal fluctuations can also occur in busy areas where many people are trying to use the same tower.

2. SIM Card Issues

Your SIM card is the gateway that connects your phone to your carrier’s network. If it is not inserted properly, damaged, or dirty, your phone may fail to authenticate with the network. Even a slightly misaligned SIM card can prevent outgoing calls.

3. Airplane Mode or Network Settings Errors

It is surprisingly easy to overlook Airplane Mode, which disables all wireless connections. Other network settings, such as manual carrier selection or misconfigured preferred network types (e.g., 4G vs. 5G), can also lead to call failures.

4. Carrier-Related Problems

Sometimes the issue is not with your device but with your carrier. Outages, network maintenance, or billing issues such as an unpaid bill or service suspension can stop you from making calls.

5. Software Glitches or Updates

Smartphones run on complex operating systems that occasionally encounter bugs. A recent update, app conflict, or corrupted cache file can temporarily interfere with call functions.

6. Hardware Malfunctions

Though less common, problems with your phone’s antenna, SIM tray, or other internal components can prevent calls. This typically requires professional repair.

Step-by-Step Fixes for Call Failures

Step 1: Check Signal Strength

Look at the bars in the corner of your screen. If there is no signal, try moving to an open area.
If indoors, step near a window or go outside to improve reception.
In rural areas, consider enabling Wi-Fi calling if your carrier supports it.

Step 2: Restart Your Phone

A restart clears temporary glitches and refreshes your network connection. Simply power down your device, wait 30 seconds, and turn it back on.

Step 3: Verify Airplane Mode

Ensure Airplane Mode is not accidentally enabled. If it is, disable it and give your phone a moment to reconnect to the network.

Step 4: Inspect Your SIM Card

Turn off your phone and remove the SIM card.
Wipe it gently with a dry, soft cloth to remove dust.
Reinsert it carefully, making sure it is properly aligned.
If your phone supports dual SIMs, try swapping slots to see if the issue persists.

Step 5: Test with Another SIM Card

Insert a different SIM card (from the same or another carrier). If calls work, your original SIM may be defective and require replacement.

Step 6: Reset Network Settings

On both Android and iOS, you can reset network settings to fix hidden configuration errors. This will restore default cellular, Wi-Fi, and Bluetooth settings. Be aware that you will need to re-enter Wi-Fi passwords afterward.

Step 7: Update Software

Check for any pending system updates. These often include bug fixes that resolve connectivity issues. Similarly, ensure your carrier settings are up to date, as outdated settings can cause call failures.

Step 8: Check Carrier Status

Visit your carrier’s website or use their app to see if there are known outages. You can also contact customer support to confirm that your account is active and in good standing.

Step 9: Enable Wi-Fi Calling

If your carrier supports it, enabling Wi-Fi calling allows you to make calls over a wireless internet connection. This is especially useful in areas with poor cellular reception.

Step 10: Perform a Factory Reset (Last Resort)

If none of the above solutions work, you can perform a factory reset. This will erase all data on your phone and restore it to its original settings. Always back up important data before proceeding.

Additional Troubleshooting for iPhone Users

Check Do Not Disturb Mode: Ensure that “Do Not Disturb” or “Focus” mode is not preventing calls.
Reinsert eSIM: If you are using an eSIM, try re-downloading it from your carrier.
Carrier Updates: Go to Settings > General > About. If a carrier settings update is available, install it.

Additional Troubleshooting for Android Users

Toggle Preferred Network Type: Go to Settings > Network & Internet > Mobile Network > Preferred Network Type and switch between 4G/5G.
Clear Phone App Cache: Navigate to Settings > Apps > Phone > Storage > Clear Cache.
Safe Mode Test: Boot into safe mode to see if a third-party app is interfering with calls.

When to Contact Your Carrier or Technician

If you have tried all the above solutions and still cannot make calls, the issue may require professional help. Contact your carrier if:

Your SIM card is damaged or unrecognized.
You suspect account-related issues such as suspension or number porting problems.
Outages or tower-related issues are affecting service in your area.

Visit a repair center or authorized technician if:

Your phone has suffered physical damage (e.g., water exposure or a drop).
Calls fail despite trying different SIM cards and networks.
You notice additional hardware problems, such as Wi-Fi or Bluetooth not working.

Preventing Future Call Issues

Keep Software Updated: Regular updates prevent bugs and improve stability.
Protect Your SIM: Avoid bending or exposing your SIM card to dust and moisture.
Maintain Good Signal: Enable Wi-Fi calling in weak signal areas.
Monitor Your Account: Ensure bills are paid on time to avoid service suspensions.
Regular Restarts: Rebooting your phone occasionally helps refresh the system.

Conclusion

Being unable to make calls can be inconvenient, but it is rarely permanent. In most cases, the problem stems from temporary glitches, weak signals, or minor misconfigurations that can be resolved with simple troubleshooting. By systematically checking signal strength, SIM card status, settings, and carrier conditions, you can usually restore calling functionality without much hassle.

If the issue persists even after trying all available fixes, it is worth contacting your carrier or seeking professional repair. Taking preventive measures such as updating your software, enabling Wi-Fi calling, and protecting your SIM card will help minimize the chances of running into call problems in the future. With these strategies, you can ensure that your phone remains a reliable communication tool when you need it most.
