How to Fix "Mobile Network Not Available" on Android — Complete 2026 Guide

The "Mobile Network Not Available" error means your phone cannot connect to a cellular network, affecting not only mobile internet but also voice calls and SMS messaging.

What Causes This Error?

The error appears for several reasons: poor or absent signal strength in remote areas or near tall buildings, a damaged or improperly inserted SIM card, dirt or corrosion on the SIM card's contacts, and temporary software glitches.

The issue can also be caused by the device broadcasting incorrect or improper radio signals.

Solutions: Easiest to Most Advanced

Fix 1: Restart the Phone

Most minor Android errors are resolved simply by restarting — it fixes bugs and crashes that slow performance and removes background apps that may be interfering with network connectivity.

Fix 2: Toggle Airplane Mode

Turning airplane mode on and off forces the phone to re-establish a fresh connection to the mobile network. Pull down the notification shade → tap Airplane Mode → wait 10 seconds → tap it again to disable.

Fix 3: Re-seat the SIM Card

Power off the phone and remove the battery (if removable) along with the SIM card. Wait a few minutes, then reinsert the SIM card, power the device back on, and check whether the network error has cleared.

Fix 4: Check and Change the Network Mode

Sometimes the problem is caused by an incorrect network setting — for instance, the phone set to 4G while the SIM only supports 3G. Go to Settings → Network & Internet → Mobile Network → Advanced → Preferred Network Type → switch the setting, wait a moment, then test.

On Android: Settings → Connections → Mobile Networks → Network Mode.

Fix 5: Set Network Operator to Automatic

If the phone is set to manually select a network operator, it can cause issues when traveling or switching areas. Switch to automatic selection: Settings → Connections → Mobile Networks → Network Operator → Automatic Search. This lets the phone connect to the best available network based on location.

Fix 6: Check and Reset APN Settings

APN configurations can sometimes become corrupted, especially after changing SIM cards or carriers. Compare current settings with those provided by your carrier. Settings → Connections → Mobile Networks → Access Point Names → three-dot menu → Reset to Default.

Fix 7: Disable VPN

An active VPN can prevent the phone from accessing the cellular network. Turn off any active VPN and attempt to reconnect to the mobile network.

Fix 8: Reset Network Settings

Resetting network settings restores all network configurations to default and often resolves persistent issues. Note: saved Wi-Fi passwords and Bluetooth connections will be erased. Settings → General Management → Reset → Reset Network Settings.

Fix 9: Secret Test Code #*#4636#*#

Dial *#*#4636#*#* from the phone dialer → select "Phone Information" → tap "Run Ping Test" → find the dropdown menu and select "GSM auto (PRL)" → tap "Turn Radio Off" → reboot the phone.

Fix 10: Update the OS

If the phone is running an outdated Android version, this may be why the mobile network error appears. Updating to the latest OS version should fix the problem. Settings → About Device → Software Update.
