6 Tricks to Make Your Phone Not Reachable and Avoid Unwanted Calls

Some people keep their mobile phones busy or not reachable to avoid unwanted calls or calls from spammers. If you want to do so as well, these 6 simple tricks will help.

Flight Mode

Flight or Airplane Mode
Flight or Airplane Mode

This is the simplest and the easiest way to get away from unwanted calls and make your cell phone unreachable. All you have to do is to turn on the flight mode or the airplane mode on your phone. 

This will let the caller know that your phone is unreachable and make them assume that this is caused by a network issue or by some other technical defects on your phone. To do this,

  • Go to the “Settings” app on your phone.
  • On the top of the setting page, you will find the “Flight” or “Airplane mode” option
  • It can also be discovered by long-pressing the phone’s Power button for more than 5 seconds. 
  • When you see the button, enable it and you will be done. 

Forward call

Other methods will make your cell phone unreachable but in this method, the incoming calls to your mobile phone will be diverted to another phone number. This phone number can be any existing phone number or an expired phone number that you are not using. 

To do this, follow these steps. 

  • Just go to the “Call Settings” tab on your cell phone.
  • There you will see the option of “Forwarding Calls”. 
  • Then, enter the phone number that is not in service or a phone number that has expired. 
  • However, you have to keep in mind that the person calling you will be notified regarding the calls being forwarded and might even be able to speculate that this is done on purpose.

Third-Party Applications

You can use any third-party apps available on the market to block unwanted calls being made to your phone. These apps are usually free and are only available for both iOS and Android. 

But their features might vary from gadget to gadget. So, it is safe for you to test them on your mobile phone and see if they are working or not.

Removing The Phone Battery

Removing your mobile phone’s battery without switching it off will make your phone unavailable when a person calls you. This method is straightforward.

Once you take the battery from your cell phone, the mobile phone will automatically switch off. You can check if your phone is reachable or not by simply calling another phone number. 

Make sure that your phone is on while doing this otherwise, the method will not work, as it will say that your mobile phone is switched off.

Aluminum Foil

Cover your cell phone with aluminum foil. It might sound like a foolish DIY idea, but it will work as there will be a network connection issue. As your mobile phone’s radio antenna will not be able to obtain any network, it will become hard for the mobile phone to receive any calls when it is wrapped in aluminum foil. 

Thus, it will leave a message to the caller saying “the mobile number you have dialed is out of the network area; try after some time”. If you are not having aluminum foil, then you can simply try putting your mobile phone in an iron box. This will also work and make your mobile phone unreachable.

Block The Phone Number

This last trick will make your mobile phone unreachable very easily but at the same time, this method is also a bit dangerous. The mobile servicer will provide an audio statement saying “the phone number that you have dialed is currently unavailable” when the mobile number is blocked. 

However, a few service providers will inform the caller that the phone number is unreachable as they have blocked it. Preferably, check if the trick is working or not by any of the alternative phone numbers that you have. 

Then, try calling from that phone number to your cell phone to check if it is unreachable or not. If the audio statement delivered is of an unavailable cell phone, then, you can just block the other phone numbers from whom you do not want to receive a call.

To block the calls on your mobile phone, you can utilize the call block feature on your phone. This can be done by following these steps. 

  • Go to the “Recent Calls” tab
  • Choose the phone number you want to block.
  • And click on the three vertical dots on the top right.
  • You will be able to see “Block Phone Number”
  • Select that to block the particular phone number.

You can also use any third-party services to block the calls. This will not make the phone number unreachable, but it will disconnect the calls as soon as the call is made to your mobile number.
