Sometimes when we go to a deserted place There may be no network on our phone but we can still make emergency calls wherever we are.

Really something like that How is it possible? is that possible?

When you want to call a friend, your phone sends a signal to the nearest network tower.

This signal goes through several stages and reaches your friend’s signal reaches the nearest tower and that’s how you can start talking. Network towers make wireless phone calls possible by sending our phone signals from one phone to another.

The bars on the corner of your phone indicate those of your network provider Shows “usable power”. If these bars disappear, the network coverage is not strong enough and you cannot make calls. How can you make an emergency call in this case?

Mobile phones need a network signal to make calls.

If the signal strength at your location is not strong enough, your phone may make calls using another carrier’s network. Most SIM cards work with GSM technology and allows you to use another provider’s network.

However, this access may be limited and therefore only emergency calls can be made. If your network provider does not have sufficient coverage, your phone connects to a ‘roaming network’.

These companies are affiliated with your provider. If the roaming network also has a weak signal, your phone can connect to the strongest signal you can make emergency calls.

In some countries, you can call emergency numbers (such as 911 or 999) even if your SIM card is not working properly.

Contrary to popular belief It is not the SIM card that connects you to the network, It is the antenna of your phone. Your SIM card only contains your phone number and carrier information.

So, making emergency calls does not require a SIM card. If the SIM card does not work, caller ID of the alarm center or may not receive the location but the call will still connect.

if that is ever the case If you are in an area without network coverage, This is bad news. Since there is no network tower nearby that can send and receive signals, your phone becomes completely ineffective.

For this reason, those traveling to deserted places should use such as satellite phones or radios Communication must guarantee security.
