No internet connection on Android and iPhone is a common problem faced by phone users everywhere. One minute, everything is going great, the sky is blue and all – then suddenly, your internet crashes, and you’re left to wonder why the colour of the sky just had to change.

Don’t let that ruin your day! This article contains the best secrets to getting back online with an even better connection. From troubleshooting tips to step-by-step fixes, you are guaranteed to find the solution to your problem here.

No Network Connection on Android and iPhones? Possible Causes

Poor coverage is the most common cause of no internet connection on Android and iPhones. If you are in an area with poor coverage or on a 2G/3G network, you might experience network connection problems. You should also check that you have not reached your data limit or are not late on your payment – if this is the case, it means your ISP has turned OFF your data.

  • Sim Card

Another widespread cause for no internet connection on Android and iPhone is the SIM card. It could be faulty, old, placed wrongly, damaged, dirty, or shifted due to a fall. Either way, if something is wrong with the SIM card, it can cause connectivity issues.

  • Updates

One of the significant reasons why it is highly recommended to update your phone regularly is because every update comes with bug fixes that are likely to correct any underlying issues on the phone. So, if you are experiencing no internet connection on Android and iPhone, your phone might be on an outdated OS. Updating it could be the solution.

Data Saver

Your phone might be set to turn on data saver mode to manage battery life automatically. Some people also turn this on themselves to manage data. However, it is essential to note that this feature also slows down the internet connection.

How to Fix No Internet Connection on Android And iPhone (Working Tips)

To fix the issue of no internet connection on Android and iPhone, you can try restarting your phone. Using the power off button, turn your phone OFF. Wait at least a minute and turn it back ON. This will allow your phone to refresh and probably fix or correct whatever is causing the connection problem. If this does not work, here are a few more fixes to try;

Fix 1: Sim Card

As aforementioned, your SIM card might be the culprit. To check this, you might need to use a SIM ejector tool or an unfolded paper clip to eject the SIM tray. Afterward, take out the SIM card and carefully inspect it for any dirt, dust, or damage – you can clean it with a clean cloth. Then, properly replace it in the tray. Be sure to turn off your phone before ejecting the SIM tray. This fix will not work for eSIMs as they are embedded and cannot be removed.

Fix 2: Updates

If your phone runs on an outdated OS, you could start experiencing issues similar to the no internet connection problem. To update an iPhone;

  1. First, connect your phone to a stable WiFi
  2. Then, go to Settings >> General >> Software Update
  3. If there is a pending update, click on Download and Install
  4. Afterwards, click on Install Now and wait for the installation to complete

To update an Android;

  1. You might need to connect to WiFi
  2. Go to Settings >> System/About Phone >> System Update >> Check for update
  3. You can also toggle on the Check automatically option, so your phone can automatically inform you of recent updates
  4. If there is an available update, an Update button should appear; click on it
  5. Then, click on the install button – it might be Install Now, Reboot and Install or Install System Software, depending on the OS
  6. Wait for the update to be installed and your phone to reboot
  7. Note that the buttons might be labeled differently depending on your OS

Fix 3: Network Reset

Rebooting your network settings will return them to factory defaults and might correct whatever is causing the connection issues you are facing. To perform a network reset;

  1. On an android, navigate to Settings >> System >> Reset options >> Reset Wi-Fi, mobile & Bluetooth >> Reset Settings
  2. On an iPhone, navigate to Settings >> General >> Transfer or Reset iPhone >> Reset >> Reset Network Settings
  3. Once it’s done, restart your phone

Note that you will need to reconnect your Bluetooth and WiFi after this.

Fix 4: Low Data Mode/Data Saver

If you have data saver mode/low data mode turned on, it could be the reason for an error preventing internet connection. You can turn it off with these steps;

  1. On Android, go to Settings >> Network & Internet >> Data Usage and toggle off Data Saver (some Android devices have Data Saver under Network & Internet)
  2. On an iPhone, go to Settings >> Mobile Data >> Mobile Data Options and toggle off Low Data Mode.

Alternatively, you can allow your phone to charge fully. If your phone turns on the data saver mode automatically due to a low battery, charging it would automatically turn it off.

On Android phones, you can also turn off data limits;

  1. Go to Settings >> Network & Internet >> Data Usage/Mobile Network
  2. Here, you can either toggle off Limit mobile data usage or toggle it on and increase the limit
  3. For Android 11 and earlier, click on Data warning & limit after step 1 above and toggle off Set data limit or Increase the limit

  3. On the SIM page, scroll down and click on Access Point Names
  4. Click on the menu icon (three dots) at the top right corner of the APN page
  5. Click on the Reset to Default option.
