What is Dual SIM and how does it work?

Right now the era of Single SIM has passed and Dual SIM has come. Look at which is now only behind the dual sim. In such a situation, do you know what is this Dual SIM? How does this Dual SIM work? What are the different types of Dual SIM? Many such questions often come in the mind of many people. But because the complete information is not available anywhere, their question always remains as a question.

There was a time when despite having a single SIM in mobile, all our work was done easily. But now with dual SIM, we are needing even more SIM. There are many advantages of Dual SIM over Single SIM, whose topic today we will try to know and understand in this article What is Dual SIM. So today I thought why should you be provided complete information about what is Dual SIM in Hindi, so that you will also get to know about this new technology. Then without delay, let's start and know how this Dual SIM technology works in Hindi.

The full form of SIM is Subscriber Identification Module. This SIM card is a card that we use in a mobile phone or smartphone so that we can connect the phone with the mobile network. A smartphone or phone that can hold two different SIM cards simultaneously is called a Dual SIM device at the same time. Having two SIM cards means that from that Dual SIM smartphone we can use any SIM card to initiate or receive phone calls.

Types of Dual SIM Cards

If you have already made up your mind to buy a new Dual SIM smartphone, then you must have knowledge about different types of Dual SIM cards. So let's try to understand and understand about the types of Dual SIM:

Dual SIM Single Standby (Passive)

This is the worst implementation of Dual SIM technology, and it is often used in affordable phones. A Dual SIM Passive phone uses two different SIM cards, but only one remains active at a time. Which means that only one SIM card works at a time, while the other one is unreachable. Similarly, if you want to use another SIM card then you have to activate it manually. The implementation of such SIM cards is not much in smartphones, rather they were used in classic mobile phones.

Dual SIM Dual Active

In this type of SIM card you can receive phone calls in both sim cards when you use them in your smartphones. Apart from this, you can receive a call in any sim card at the same time. In Dual SIM Dual Active smartphones, both of their SIM cards are permanently active and when you are using one for conversation, the other is also active and can also receive calls, messages and data. For example, if you are chatting in a SIM then when a call comes in the second SIM, then you are notified about the subject.

The disadvantage of this Dual SIM Dual Active phones is that these devices use two radio transceivers, one SIM card for each. It also means that they consume more battery than single sim smartphone. Apart from this, manufacturing them is also more expensive, due to which the prices of these phones are higher. So they are rarely implemented in smartphones due to their costly.

Dual SIM Dual Standby

This type is a hybrid between Dual SIM Standby and Dual SIM Dual Active. Dual SIM Dual Standby has two active SIM cards on your smartphone, and both of them use a radio transceiver. But both remain active until you are using both of them, hence their name is Dual Standby.

As long as both these SIM cards are in standby mode, you can use any card to make and receive calls. But as soon as you use one SIM card for a call, the other one becomes inactive and then cannot be used actively. We cannot call this technology ideal but it is not very expensive and is very widespread in modern smartphones.

Dual standby phones require only extra space for a more SIM card. That's why these phones cost a little more than basic phones, but that too is a marginal difference. Let us try to understand these dual sim types very easily. Using a simple comparison table.

Can we use both 3G / 4G data plan in both SIM cards in a Dual SIM Smartphone?

The answer is yes, but it also depends on the Dual SIM implementation, which is chosen by the manufacturer of the smarphone. Manufacturers see how much they cost to make a phone and whether they have profit margins or not. Creating a dual SIM smartphone in which one SIM card supports 4G data connections and the other 2G, so making it easier and affordable.Is ta 4G + 2G is easily combined into a Dual SIM Dual Standby mode and the same radio frequencies are also used.

Whereas if you want to create a dual SIM smartphone in which one SIM card supports 4G connection and another supports 3G or even 4G, then it means that your phone's processor must be powerful, which is two high -Speed ​​be able to simultaneously support data connections. In addition, its manufacturing cost is also higher than before. Most Dual SIM smartphones available in the market offer 4G + 2G data connections.
