Assalamualaikum Friend, How are you all? You all must have heard about e-SIM. You must be talking on the phone and for that you need a SIM card in the mobile. Today I will not talk about the SIM card. Today I will talk about the electronic SIM card. The SIM card that you can't hold in your hand, you can't see with your eyes, but it will be in your phone with which you can talk. E-SIM. Its name is E-SIM.

It can be called virtual. We have to buy the SIM separately from the store then if there is in the phone with the motherboard of the phone then there are many benefits. But there are also major difficulties. Lastly, there is nothing else to say about the inconvenience.

What is e-SIM

E-SIM has been launched in different countries of the world. Bangladesh came on 16th December 2021 and if you have e-SIM, we can usually use this SIM as second SIM in iPhone and Google Pixel phone.

There is a physical SIM, the kind of SIM we bought from the store. I can't use the SIM that I can hold in my hand. There is another slot that is for SIM. The e-SIM thing is that there will be an electronic circuit in the motherboard of my mobile.

Its size is very small, very small in which will be programmed my phone number, all the details of my SIM, everything starting from my ID. In other words, whatever is in the memory of a SIM will be filled in my phone and will be built.

How to activate e-SIM?

E-SIM will be activated when you go to your service provider. The service provider means you go to Airtel, you go to Geo, you go to Grameenphone in Bangladesh, you go to Teletalk and they will program your phone and fill that SIM.

In fact, the SIM is full, it will turn it on. It will give some program or some code. And if you don't go in front of them then you can do it via SMS sitting in your room. But if you have your email ID registered for it. This matter must be confirmed.

If your email has registration, then from mobile, if you send one-to-one message to Airtel. In reply to the message you will get a reply that yes a QR code is being sent to your email id. Once you scan it, your SIM will be activated.

Then you go to the email id, scan the QR code and after scanning your SIM is not turned on! The reason why it will not be launched is because your mobile cannot understand which plane you are on, SIM card cannot understand.

So for that you have to go to your mobile settings, there you have to go to mobile data and activate your existing plan. And you can do that from there through QR code. There are different types of rules in this case. So you can easily activate the SIM on your mobile.

The good side of e-SIM

You will get many benefits by setting up e-SIM. You do not want to be frustrated if you cannot get the right pitch so invest in a good capo. Besides, when we use a lot of different data plans together, I have to open one SIM from my mobile and get another SIM.

These problems will not be needed. You want to switch between the two service providers Grameenphone's Teletalk type Airtel and Geo. Then you just have to login with the user ID and password and you just have to change the provider then you can go from Geo to Airtel. You will be able to change Teletalk from Grameenphone again.

And you don't have to give a separate place to insert SIM card in mobile. Which will save some space. Yes! There will not be enough space to go there and you will fall asleep with a blanket. But the space that a mobile phone will save is the size of a complex.

There it becomes very important or final. As a result, the company may not be able to increase the battery there, but another company may be able to provide it. A feature can give one to your mobile. On the plus side, it eliminates unhealthy sugary foods from one's diet.

However, the most benefit that I said is that your phone's SIM will not be lost, this facility will not be bad. Many may have a problem here. From the physical SIM card you had, to the e-SIM card you got.

If the phone number remains the same, will the two SIM cards work together? Neither will run at the same time. The physical SIM card you had will be turned off at the moment the e-SIM card is turned on. That means your number will run on any one SIM at a time. The two will never go together.

The bad side of e-SIM

Of e-sim. There are a lot of bad aspects. And the first thing I will say about the bad side is that you can't change your phone's SIM card at will. So your phone seems to have run out of battery. You will never get the benefit of talking on your friend's phone with the SIM.

The second bad thing is that you think you will change your mobile. Today it stands like this. We are changing the mobile every six months except for three months. When changing mobile, you need to activate the SIM again. The old SIM will work but you have to go to the store and reactivate it for another phone.

A more important disadvantage of SIM cards is that the SIM cannot be changed in the first place. In other words, the number one plot of our mobile phone has one SIM. Plot number two has another SIM. We can change these two SIMs as we wish and we can change it from there to switch or change the mobile phone.

E-SIM cards do not have the flexibility to open and change. Also when we reset mobile phone many of us reset occasionally. Even after resetting, the configuration of the SIM card is gone. You have to reset the key from your SIM card with the new configuration from the company.

So in that case these are the problems. Another problem with e-SIM lately is the problem of phone being hacked. That means whenever you are going more digital. Going to scan the QR code, the matter of email is going on, the fear of hacking the phone is increasing. This is a new fraud, so I shared it with you.

But you should note that most of the e-SIM SIMs are convenient yet the thing has not been successful for so many years. From the counterpoint data we know that in 2018 only 364 million e-SIMs were activated worldwide.

And there Counterpoint says that by 2025, there will be two billion activated in the whole world. How will it be? How will the number of SIMs increase? How will the sales increase? Not for our mobile phones, not at all.

The biggest point of e-SIM will be that in the case of automobiles, the various automobile IoT devices that we use at home are becoming increasingly smart, so SIMs will be needed in the days to come. That's when e-SIM will increase.

E-SIM has not been so successful for mobile. This is because once you change this thing, you will see that there is a problem with various activations. Problems occur at different times in a single stay. It's an event and for him it has not become popular.

But e-SIM will be more popular in the future and activating e-SIM means you are moving a bit towards that. Being futuristic.
