- Emergency calls are made successfully even when there is no network.
- The phone shares location information by connecting to a nearby tower.
- Telecom companies are obliged to give priority to emergency calls.
How Emergency Calls Work: If there is no network in your phone then you cannot call or message anything. No matter how hard you try, you cannot contact anyone without network, but as soon as you try to contact emergency services, your phone gets connected even without network. This means that even in case of network failure, you can contact the police and other emergency services. After all, how does this happen? Today we will know the answer to this.
How to make emergency calls without network?
Both technology and rules work behind this. First let’s talk about technology. When you make an emergency call without any network, your phone searches for the nearest tower. Even if you do not have a SIM card of the company of this tower, it will connect to the nearest tower. After this, the internal hardware and antenna installed in your phone use a universal emergency protocol. There is no need to have a SIM card or service plan. As soon as you dial a number like 100 or 112 from your phone, your phone automatically goes into emergency mode. That means, along with the call, it also shares your location with emergency services.
For this the phone system takes the help of nearby tower or any WiFi signal. Once you know your location, it becomes easier for emergency services to reach you. It is important to keep in mind that for emergency calls it is necessary to have a tower nearby. If there is no tower for several kilometers from where you are standing, it may be difficult to contact emergency services.
Rules also help
This whole game is not just about technology. Some rules also work behind this. For example, every company is required to give priority to emergency calls. That means companies cannot stop emergency calls from passing through. If a company’s network is full and there is no space for new calls, then it is necessary to pass the emergency call by disconnecting the active call. However, for this it is necessary to have a local connection. This means that you will not be able to make emergency calls without network while going abroad.
