How to Check Network Settings for Call Issues -

Getting your Trinity Audio player ready...

If your phone cannot make calls, one of the most common reasons is incorrect network settings. Both Android and iPhone devices rely on proper network configuration to connect to your carrier. This guide explains how to check and fix network settings step by step to restore calling functionality.

Why Network Settings Matter

Your phone’s network settings determine how it connects to your carrier’s cellular network. Incorrect settings can cause:

Failed outgoing calls
Dropped calls
Slow mobile data
SIM card not recognized

Even if your SIM card is active and the signal is strong, improper settings can block calls.

Step 1: Check Mobile Network Selection

Android:

Go to Settings → Connections → Mobile Networks → Network Operators.
Select “Search networks” to see available carriers.
Choose your network manually or leave it on automatic.

iPhone:

Go to Settings → Cellular → Network Selection.
Toggle Automatic on, or select your carrier manually if needed.

Step 2: Verify Network Mode

Your phone may support multiple technologies: 2G, 3G, 4G, and 5G. If your phone is set to a mode not supported by your carrier, calls may fail.

Android:

Settings → Connections → Mobile Networks → Network Mode
Choose 4G/3G/2G Auto (recommended).

iPhone:

Settings → Cellular → Cellular Data Options → Voice & Data
Choose the correct mode (e.g., 4G, LTE) supported by your carrier.

Step 3: Check SIM Status

A disabled or malfunctioning SIM can prevent calls.

Steps:

Remove your SIM card and reinsert it.
Test the SIM in another phone to ensure it works.
Check for any SIM restrictions from your carrier.

Step 4: Reset Network Settings

If all else fails, resetting network settings can resolve hidden configuration errors.

Android:

Settings → System → Reset Options → Reset Wi-Fi, Mobile & Bluetooth

iPhone:

Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings

Note: Resetting network settings removes saved Wi-Fi passwords and Bluetooth connections, but it will not erase your data.

Step 5: Check Carrier Updates

Carriers sometimes release updates to improve connectivity. Ensure your phone has the latest carrier settings installed.

Android: Settings → About Phone → Software Update → Carrier Update
iPhone: Settings → General → About (a popup appears if an update is available)

Additional Tips

Turn Airplane Mode on and off to refresh the network.
Ensure your phone’s software is updated to the latest version.
Move to an area with better coverage if the signal is weak.
Test your SIM card in another phone to rule out hardware issues.

Conclusion

Checking and adjusting your network settings is often the fastest way to fix call issues. Ensuring the correct network mode, SIM status, carrier settings, and network selection can restore outgoing and incoming calls. If problems persist even after resetting and updating, contact your carrier or visit an authorized service center.
