Common network issues and solutions

1. No service or signal messages

When your phone struggles to connect to the network, it limits your ability to make calls, send texts, or use data. Here's how to troubleshoot:

Why Does “Mobile Network Not Available” Happen?

This error can appear for several reasons:

• Weak coverage

You may be in an area with poor reception or dead zones.

• SIM card issues

A damaged, dirty, or improperly inserted SIM can block your phone from connecting.

• APN misconfiguration

Incorrect Access Point Name (APN) settings may prevent mobile data access.

• Outdated software

Not updating your device’s software can cause compatibility problems with the network.

• Temporary network outages

Carrier-side disruptions may also trigger the error.

How to Fix Mobile Network Not Available Error

• Restart Your Device

A simple reboot can often refresh your connection. Power off, wait 30 seconds, and turn it back on.

• Toggle Airplane Mode

Try to re-establish a network connection to the nearest signal tower by activating Airplane mode, and then deactivating it.

• Check Your SIM Card

Ensure that the SIM card is properly seated and clean. Turn off your phone, remove and clean the SIM, then re-insert it and power it on. Consider switching to an eSIM to avoid these hassles - start by comparing the best eSIM plans in Singapore.

• Restore Factory Settings

This last resort can resolve the majority of underlying software issues. But remember to back up all your important data before performing a factory reset as this process will erase all personal data from your device.

• Locate Network Towers

Aim your phone towards the tower it's connected to. Use platforms like Cell Mapper to find your nearest mobile network in Singapore.

• Select Network Operator Manually

Go to your phone’s network settings and choose your carrier manually. This can sometimes force your device to reconnect to the proper network when auto-selection fails.

• Update Phone Software

Outdated software can cause compatibility issues. Make sure your device is updated to the latest OS and carrier settings to ensure optimal connectivity.

• Reset Network Settings

If you still encounter issues, resetting network settings can clear old configurations that might be blocking your connection. On most phones, this can be found in Settings > General Management > Reset > Reset Network Settings.

• Try Another SIM Card

Insert a different SIM to see if the issue lies with your current SIM card. If the problem disappears, you may need a replacement SIM from your carrier.

2. Slow data speeds

● Close Unused Apps: Running apps in the background can hog bandwidth, so make sure to close any apps you are not utilising currently.

● Data Usage Settings: Manage your location and background app refresh settings to conserve data and improve connection quality.

3. Frequent disconnections

● Network Settings Reset: Sometimes resetting your network settings can provide a more stable connection.

● Software Updates: Ensure your device's software and apps are up-to-date for optimal performance.

Fixing Network Issues on Android

When you’re using an Android phone such as Samsung, Oppo, or Xiaomi, network errors like “mobile network not available” or “I lost my 4G network” can often be solved through the following steps:

Resetting Network Settings (Samsung, Oppo, Xiaomi, etc.)

If you’re facing persistent issues, resetting your network settings can help clear out old configurations.

• On Samsung devices, go to:
  Settings > General Management > Reset > Reset Network Settings.

• On Oppo/Xiaomi and other Android brands, look under System Settings > Reset Options > Reset Wi-Fi, Mobile & Bluetooth.

This will erase saved Wi-Fi networks, Bluetooth pairings, and APN details, so be prepared to reconnect after the reset.

Check APN Settings on Android

The Access Point Name (APN) defines how your device connects to the internet. If APN settings are missing or incorrect, you may see errors like “cellular network not available.”

• Go to Settings > Connections > Mobile Networks > Access Point Names.

• Ensure your telco’s official APN is selected.

• For Circles.Life Singapore, you can find the correct APN settings here.

Update Carrier Settings & Switch Between 4G/5G

Sometimes, the issue isn’t your phone but the network mode.

• Toggle between 4G and 5G under Settings > Connections > Mobile Networks > Preferred Network Type.

• If you’re on the MRT or in areas with weaker 5G, switching back to 4G can help stabilize your connection.

• Also, check for Carrier Settings Updates under your phone’s software update menu.

Fixing Network Issues on iPhone

Apple users may also face issues like “iPhone unable to join the network WiFi”, “iPhone 7 connectivity issues”, or “iPhone searching for network.” These can often be resolved by:

• Restarting your iPhone to refresh the network connection.

• Updating iOS and Carrier Settings to ensure compatibility with your telco.

• Resetting Network Settings: Go to Settings > General > Reset > Reset Network Settings.

• Reinserting your SIM or switching to eSIM for a more stable connection.

• If the issue persists, refer to Apple’s official network troubleshooting guide.

Tips for Preventing Future Connectivity Problems

While network issues can happen, you can minimize disruptions with these simple tips:

• Keep your device updated: Install the latest OS and carrier updates regularly.

• Monitor data usage: Avoid hitting caps that may throttle your speed.

• Check coverage maps: Use Circles.Life’s 5G coverage map to ensure you’re within strong signal zones.

• Use correct APN settings: Always double-check your APN to avoid blocked data access.

Understand When It’s a SIM or Carrier Problem

Sometimes the problem isn’t your phone at all. It could be the SIM card or the network carrier.

Possible SIM Issues:

• Damaged or misaligned SIM card.

• Inactive SIM (e.g., after number porting).

• Older SIM cards not supporting 4G/5G.

Possible Carrier Issues:

• Temporary network outages.

• Coverage dead zones (like basements or MRT tunnels).

• Line suspension due to billing issues.

If you suspect a SIM issue, request a replacement via Circles.Life SIM support.

Other Connectivity Issues & Fixes

Bluetooth Connectivity Issues

Bluetooth failures often happen due to outdated firmware, interference, or pairing conflicts.

Steps to Fix Bluetooth Issues:

1. Toggle Bluetooth off and back on.

2. Forget the paired device and re-pair it.

3. Restart your device.

4. Update your OS and Bluetooth firmware.

Wi-Fi Connectivity Issues

Wi-Fi problems like “iPhone unable to join the network WiFi” are usually caused by router misconfiguration, weak signals, or incorrect passwords.

Steps to Fix Wi-Fi Issues:

1. Restart your router and phone.

2. Forget the Wi-Fi network and reconnect.

3. Ensure your phone is set to the correct frequency band (2.4GHz vs 5GHz).

4. Reset network settings if the issue persists.

Extra tips for optimal connectivity

● Invest in a Signal Booster: Mobile phone signal boosters (or repeaters) scan the surrounding area for available signals, amplify them, and then broadcast the strengthened signals into an area that has a weak or non-existent signal. If your home or workplace is located in an area with poor reception, consider installing one.

● Use Wi-Fi for Phone Calls: If all else fails, make calls or send messages using your Wi-Fi connection rather than a traditional mobile service. If you HAVE to use public Wi-Fi, make sure that you're aware of the potential dangers and safeguard yourself from cybercrimes. Read more in this guide.

   This usually indicates weak coverage, SIM issues, or a temporary outage.
