IF THERE IS NO NETWORK HOW DOES AN EMERGENCY CALL WORK?||The Interesting Fact Behind The “No Service, Emergency Calls Only!” on your Smartphone|| Rapid Info ||

In these days smartphone has become part of our life and almost everyone is using mobile. many of us will have a doubt and that is, even with no signal in our sim or even there is no sim in our mobile how we can make calls to emergency numbers like Ambulance, Police and fire station. Now let's find the actual secret behind this.

The Real Secret: 

Most of us will think that to make a call sim will send the signal but our sim doesn't send the signal to the tower. The antenna which is present in our mobile will send the signal to the tower. Then you may get the doubt then what is the purpose of a sim. Sim will give us uniqueness by proving different phone number to each to sim is used to know the details of the caller and to check if the caller had enough balance to place a call or not and also our sim is used to know our call data.

Basically, when we make a call our sim will check whether we have enough balance to place a call or not and if you had enough balance your sim will allow the signal from the antenna in your mobile to connect with the nearest tower. 

Almost in all mobile emergency numbers are saved. When you are making a call to an emergency number the antenna in our mobile will connect to the nearest tower without taking permission of our sim. For example, you are using Jio sim and you are not receiving Jio signal but Airtel signal is available in your area, then when you make an emergency call it will connect to the nearest airtel tower. If you have no towers in your area you cannot make an emergency call. So you can make an emergency call using any signal of any sim.

So this is the Actual reason behind this. I hope this helped you to find the answer.
