Common Symptoms of Network Problems
Before solving network issues, it’s crucial to identify the signs. Here are the most reported problems:
- Mobile data does not work even when enabled
- The phone shows “No Service” or “Emergency Calls Only”
- Calls drop frequently or cannot connect
- Slow browsing despite full signal bars
- SIM card errors or frequent disconnections
Recognizing these symptoms helps users apply the right solution quickly.
Step 1: Restart Your Android Device
The simplest solution is often the most effective. Restarting your phone clears temporary bugs and resets network functions.
How to do it:
Hold the power button, choose “Restart,” and wait for the device to reboot. After restarting, check if the network functions normally again.
Step 2: Toggle Airplane Mode
Turning airplane mode on and off forces the device to reconnect to the nearest cell tower. This method often resolves minor disruptions.
How to do it:
Swipe down your notification bar, tap the airplane icon, wait 10 seconds, then tap again to disable it.
This trick resets all network modules, including Wi-Fi, mobile data, and Bluetooth.
Step 3: Check Network Settings and Carrier Selection
Sometimes, network problems occur because of incorrect settings or a switch to the wrong network operator.
Steps to fix it:
- Go to Settings > Connections > Mobile Networks
- Tap Network Operators
- Choose Search Networks manually
- Select your correct provider from the list
If set to automatic, the phone might occasionally switch to an unstable tower, so manual selection is useful when traveling.
Step 4: Reset Network Settings
When nothing else works, resetting the network settings can solve more complex issues. This will remove all saved Wi-Fi passwords, paired Bluetooth devices, and mobile preferences.
To reset:
- Open Settings
- Go to General Management > Reset > Reset Network Settings
- Confirm the reset
This method is recommended by Tech by Android as a standard fix after major software updates.

Step 5: Remove and Reinsert SIM Card
Your SIM card may be misaligned or dirty. Removing and cleaning it can restore the signal.
Instructions:
- Turn off your phone
- Remove the SIM card
- Gently clean the chip with a microfiber cloth
- Reinsert the SIM properly
- Turn the phone back on and check connectivity
If the problem persists, try using another SIM card to verify whether the issue is hardware or network-related.
Step 6: Update Software to Latest Version
Outdated software might contain bugs that affect the network module. Manufacturers release updates to patch such issues.
How to check for updates:
- Navigate to Settings > Software Update > Download and Install
- Make sure your phone is charged and connected to Wi-Fi
- Install any available updates
Techbyandroid.com also recommends enabling auto-updates to receive bug fixes on time.
Step 7: Switch Between Network Modes
Modern phones support various modes such as 5G, LTE, and 3G. Switching modes can stabilize your signal.
To change mode:
- Go to Settings > Connections > Mobile Networks > Network Mode
- Choose a stable mode based on your area (e.g., LTE/3G/2G auto)
Users in rural or low-signal areas may get better service on 3G or LTE rather than 5G.
Step 8: Use Safe Mode to Detect App Conflicts
Sometimes, third-party apps can interfere with network connectivity. Safe mode disables these apps and helps isolate the problem.
How to enter Safe Mode:
- Press and hold the power button
- Tap and hold the Power Off icon until Safe Mode appears
- Tap to confirm and boot into Safe Mode
If the network works normally, an app is likely the cause. Uninstall recently downloaded apps one by one to identify the culprit.
When to Visit a Technician
If all methods fail, your phone may have a hardware issue. Problems with the internal antenna, SIM tray, or logic board need professional repair.
Bring your phone to an authorized service center if:
- You see “No SIM Card Detected” frequently
- The phone was dropped or exposed to water recently
- Multiple SIM cards fail to work
Don’t delay if your device is still under warranty.
Final Thoughts
Network problems on Android phones can be annoying but are usually easy to fix with the right steps. In 2025, Android devices offer more tools than ever to troubleshoot these issues independently.
Using updated practices from Tech by Android, users can solve most network errors without a technician’s help. Stay informed and make sure your device software and settings are always up to date.
