Even if there is no network, how can you call for help?
Imagine yourself in an accident in a remote location where you are unable to move and there is no one nearby to assist you.
The only thing you can do is call an ambulance ,Mohali Ambulance Service in Sector 46 Mohali, but your network operator doesn’t offer service there! You know who to call!
Isn’t that a sticky situation? Because your network provider doesn’t operate there, you could lose a limb or, God forbid, your life.
You can still call an ambulance even if your network is unavailable, but at least one of the registered networks must be accessible. So, don’t worry.
In India, you can call an emergency number regardless of your network provider.
Consider the scenario where the Vodafone signal is available but the Airtel signal is not. Through Vodafone’s network, your phone continues to function.
Why would you even need network coverage?
Wireless telephony is absolutely impossible without network towers.
If you want to call a friend, pressing the green or other colour “call” button on your phone will immediately send a signal to the nearest network tower.
The signal then travels through a number of steps to reach another tower.
Finally, your friend’s phone picks up the tower signals, and presto! You two are conversing!
The “usable strength” of your network service provider is indicated by the bars in the top corner of your phone.
The network coverage is insufficient to make calls, send SMS messages, etc. if the bars vanish. How can you place those “emergency calls” if that is the case?
Can you call for help when there is no service?
Like many other people, you might believe that your phone has some complex technology inside that enables it to place emergency calls, but that is regrettably untrue.
Cell phones need network coverage to make calls, as was previously mentioned.
However, if your service provider’s mobile network’s usable signal strength is insufficient where you are placing the call, they will use another service provider’s network whose usable signal strength is sufficient to place the call.
Because of the way GSM technology is built, you can use another service provider’s network if your own service provider’s network is not available.
However, you won’t have much access to it; this is why there is an “emergency call” restriction.
Your phone, therefore, camps on a “Roaming network” in the absence of adequate network coverage from your own service provider nearby (these are those companies that have links with your own company).
If the roaming network is also not robust enough, your phone will automatically switch to the strongest network signal in your immediate area, regardless of the provider. In this situation, emergency calls to Ambulance Service in Sector 46 Mohali can be placed.
What if your SIM card isn’t functioning?
Even if their SIM cards are malfunctioning, people can connect to emergency numbers like 911 or 999 in some nations.
Keep in mind that your phone’s antenna, not its SIM card, is what connects you to a network tower.
Making an emergency call is not necessary because a SIM card only contains the phone number and carrier information.
Due to the malfunctioning SIM in these situations, the emergency service centre is unable to obtain the caller’s location or caller ID, but the call can still be connected.
