You may get “no signal on your Android phone” or “Android Says No Service” at times. It’s aggravating, particularly when you need your phone the most. You may be wondering why your Android claims there is no service. This is a frequent problem that may be caused by a variety of reasons such as hardware issues, a null IMEI, and more. The following advice will be helpful if your Android smartphone has stopped getting network signals or if you are wondering Why Does My Phone Say No Service.

How Do I Fix The Error “Android Says No Service”?

As a result, we’ve prepared a list of eight potential remedies for the Android No Service or SIM Card Detection problem. Let’s have a look at the methods below to see if any of them may help you with your “No service or signal” issue!

Turn off your Android device.

Restarting your device is the simplest and quickest option you may attempt. One of the most often suggested and proven to be extremely helpful remedies is to restart your smartphone. This will solve a variety of issues and errors on Android devices, including “sim card not recognized” and “no service” errors. Try a hard restart. Hard restarting your smartphone clears glitches, fixes minor problems, and refreshes your Android system momentarily. It will undoubtedly restore your service or signal. Here’s how to do it:

  • For 10 seconds, press and hold the volume down and power buttons together. Your device will be forced to switch off and on again as a result of this action.
  • When the logo appears, let go of both keys and wait for the phone to reboot.

Remove the battery from the device. (If at all possible)

This may seem stupid, but removing and re-inserting your battery will assist you with these issues. Unplug your phone from any power source and turn it off. Remove the battery and wait at least 30 seconds before replacing it. Also, turn on your gadget.

Replace your SIM card.

It’s possible that the sim card isn’t inserted correctly if your Android indicates no service or Sim Card not detected. It’s possible that the SIM has gotten misaligned or that it hasn’t been properly inserted. As a result, double-check that the SIM Card is securely inserted into your smartphone. To do this, you must first remove the sim card from its tray and then correctly reinsert it.


Mode: Airplane

Enabling Airplane Mode, which disables Bluetooth and Wi-Fi and inhibits the mobile phone’s ability to connect to cellular networks or disconnect the signal manually, is another highly efficient remedy for the no service or signal problem on Android. By activating and removing Airplane mode on your smartphone, you are essentially restarting functionality such as cellular and Wi-Fi connections, as well as refreshing all Network Settings. This will undoubtedly assist you in restoring your device network. This disconnects the phone from the mobile tower and then reconnects it.


Select Network Operators by Hand

In most cases, all Android smartphones automatically connect to your phone company’s network operators. If this network is not accessible or Android indicates that there is no service, you may disable the option and manually search for mobile networks. This will allow you to manually choose network operators. Here’s how to do it:

  • On your smartphone, go to Settings.
  • Disable the “automatically pick network” option by tapping on mobile networks.
  • You may now view a list of available networks in your region.
  • Choose the right option and check whether your Android no signal issue is resolved.
  • After choosing the preferred network, you may need to restart your Android smartphone to check whether the changes take effect.

Perform a Ping Test

Because it’s linked to a deactivated cellular radio signal, an Android smartphone may display “No Service” or “No Signal.” This repair isn’t as simple as browsing menus or pressing a few buttons, but it’s also not technically difficult. All you have to do is stick to the easy instructions.

  • Activate your phone dialer
  • To enter Service Mode, dial *#*#4636#*#* and press *#*#4636#*#*.
  • Select Phone Information or Device Information from the drop-down menu.
  • Choose Run Ping Test.
  • When the test is finished, look at the radio data at the bottom of the screen and switch on the radio if it’s been turned off.
  • Restart your device after this is done.

Errors in ESN

A poor ESN isn’t the fault of the phone; it’s the fault of the cellular provider. The term ESN stands for Electronic Serial Number, and if your ESN is corrupt, you may get no service errors on your Android smartphone. The ESN may become removed or invalidated at any moment. It’s a difficult subject to convey here. However, it is simple to fix and extremely effective. Here’s how to do it:

  • To view the ESN, open the phone’s dialer and dial (*#06#).
  • If the ESN reads null, it’s possible that it’s corrupted, which will need some remedies.
  • If the ESN seems to be correct, reopen the dialer and dial (*#*#197328640#*#*) or (*#197328640#) to enter Command Mode.
  • Option 1 for Field Test Mode is selected after the Common option (FTM)
  • If FTM reports as ON, it must be deactivated. To do so, press the menu key before exiting the Command screen and follow the on-screen instructions.
  • Return to the keypad and choose Option 2 to switch off FTM.
  • Remove the SIM card and battery from the smartphone, wait two minutes, and then replace just the battery.
  • Restart the phone and enter (*#197328640#) into the dialer for the second time.
  • Debug, Phone Control, Nas Control, RRC, and finally RRC Revision will fix the void ESN problem.
  • Option 5 should be chosen.

Restore the factory defaults

Some issues are more difficult to repair than others, and how to fix no signal or service Android occasionally necessitates a more forceful approach. Consider wiping your phone’s data and resetting it to factory defaults (Reset your phone to factory settings)

If the preceding methods fail to resolve the Android says no service error, the user has the option of completely resetting their device to resolve the problem.

IMPORTANT: A factory data reset will wipe your phone clean of any data. All applications and their related data will be removed, while any data saved in your Google Account will be restored. We suggest backing up your phone before doing a factory data reset.

Consider further troubleshooting if your Android no signal problem or SIM card not recognized error persists. Please keep in mind that this is only used as a last resort if all other alternatives have failed. Because this procedure will erase all of your Android’s applications and data, it’s critical that you back up your device beforehand.

You may do a factory reset by following the instructions below.

By using the Recovery mode.

  • Switch off your Android smartphone.
  • To enter Recovery Mode, press and hold the Volume Up + Volume Down + Power keys at the same time.
  • To browse the Recovery Mode menu, use the volume (+,-) buttons.
  • Highlight Wipe data/factory reset using the Volume buttons to navigate through the menu.
  • To choose, press the Power button.
  • To confirm the reset, highlight and choose Yes.
  • You’ll be sent back to the same recovery mode menu after the reset is complete. Select Reboot system now by pressing the Power button.

Using Settings Manually,

  • To begin, go to the settings menu. Scroll down and select the accounts and sync option; you’ll find your Google account there; click it, then click the more button to delete it.
  • Then go back to settings, choose about the phone, and then backup and reset.
