If we buy a new phone, of course there is something in it. SIM card not found. For this reason, when turning on the phone, we see certain signs in the signal phrase that indicate that no SIM card is inserted. If the name of the service provider that gave you the line to install is where it should be,’Emergency calls onlyThere is a text like ‘.

Of course, we all know that these are also numbers such as 112 in our country and 911 abroad. But calling without a SIM card not being able to The fact that our devices can call 112 causes some confusion. Let’s clear up this confusion now.

First we need to understand the logic of the SIM card:

Our ID numbers are personal and we handle these unique numbers in government offices. These identities are also ours. to the Republic of Turkey It shows that we are connected. When you insert a SIM card into your phone, your device will also gets identity and you also have a unique phone number.

Let’s say you bought your SIM card from operator X. Your phone is now near your current location of operator X. base stations It will search and show you the signal strength accordingly. Although Carrier Y’s base station is closer to you, your signal may appear lower than you expect because your phone uses Carrier X’s card.

This is why different operators in different parts of the country offer signals of different strengths:

is already in between rivalry also stems from this. If you live in a rural area and your phone can’t get enough signal from an operator, then you go to several alternatives. For this reason, operators everywhere It works to provide a strong, stable and fast internet experience.

Think of your carrier’s base stations as points in different parts of the map:

Messenger communication

This one red get color. Have another operator distribute the base stations in the same way and also in blue Let’s show it. A third operator vegetable get color. The SIM cards connected to the red operator will not see the green or blue base stations. In other words, each operator can connect its own SIM card to its base stations.

So what happens when it comes to emergency numbers?

We can say that all these different colors that we mentioned are turning gray. In other words, when it comes to emergency numbers, it doesn’t matter which operator the base stations are connected to. For example Vodafone’s Suppose you are using a SIM card. call 112 If you want to make a call, you can also make this call if no base station is connected to Vodafone.

Because when you want to call this emergency number, your phone is connected. from the operator not to the signal, on every signal trying to reach. Therefore, if, for example, there is a Türk Telekom base station nearby, it will not hesitate to receive the signal from there.

So it’s not really the SIM cards you can use to make calls:

They only give your phone its identity and allow you to search and browse the web within their frames. But your SIM card however not that your phone can make emergency calls, SIM cards are only one key indicates that he is on duty.

In short, these are of course essential to keep in touch with people in our daily lives. But if the only problem is that the phone can make calls, the SIM cards can be made using the 112 example. not necessary we can say. After all, this is a matter between operators. If your number was an emergency, you could be called anywhere, regardless of the operator.
