Friends, nowadays, a new word is heard a lot in the world of phones – “eSIM.” Many people have a question in their minds: What is this eSIM? Is it useful to me? And will it work in my new 5G phone?” This is a very important question. So today we try to know. What is this eSIM, how does it work and which 5G phones support it, so that when you buy a new phone, you have complete information.

Why is eSIM becoming popular in India?

Friends, in the old days, there used to be a small tray to insert the SIM card in the phone, and we used to fit the plastic SIM card in it. But now technology has advanced a lot. There are many new things like wireless charging, waterproof phones and eSIM. It is gradually becoming very popular in India too.

People are getting more attracted towards it. Because one is for convenience, the other is for security. Especially when we talk about 5G phones, companies want the phones to be thin, and there should be more space inside for other parts. Therefore, this eSIM is now becoming a standard feature in high-end phones. If you are thinking of buying a new 5G phone, then it is very important to know about eSIM. So, let’s know about it in detail.

What is eSIM, and how does it work in simple words?

Let me explain clearly: eSIM means “embedded SIM.” Embedded means fixed inside the phone. Imagine, this is not a physical plastic SIM card that you put in the phone. This is a small chip fixed permanently inside the phone itself. This chip works exactly like your normal SIM card. The only difference is that you cannot take it out or put it in.

How does it work?

You have to contact your network provider (like Jio, Airtel, Vodafone Idea). They will give you a QR code or an activation code. You will scan that code with your phone (there is an option in the phone’s settings). And that’s it, your phone number and network profile will be downloaded onto that eSIM chip. The phone will immediately connect to the network. When you want to change the network, you don’t have to put in a new plastic SIM. You can just go into settings and download a new network profile if your provider supports it. This is a completely digital way to use a SIM.

Benefits of using eSIM in a 5G smartphone:

Honestly, this SIM can be very useful for us, especially with 5G phones. It has some big benefits:

1. More Space in Phone: Because there is no physical SIM tray, phone makers get more space inside. They can use that space to put bigger batteries or other good features. Phones can also be made thinner.
2. No SIM Swapping Hassle: Imagine you keep changing SIM cards, or you lose your SIM card? With this sim, there is no such tension. You just have to go into settings and change the profile. It’s very easy, even when travelling. You can also download another country’s network on this SIM without searching for a physical SIM. If you want hassle-free SIM management, especially when travelling abroad, eSIM is a blessing.
3. Enhanced Security: A physical SIM cannot be taken out of the phone and stolen by anyone. If your phone is lost or stolen, the thief cannot take out your SIM card. It also becomes easier to track the phone. This gives an extra layer of security to your phone.
4. Dual SIM Made Easy: Many 5G phones support dual SIM. You can use one physical SIM and one eSIM together. Or some phones might support two eSIMs, too. This is very convenient for those who use two numbers.
5. Water Resistance Improved: When the phone has no SIM tray, manufacturers find it even easier to make the phone water resistant because they eliminate one small hole in the device.

So, this SIM technology is not just a new feature. It gives many practical benefits.
