What is eSIM? What Does It Mean for Your New Phone or Smart Watch?

by elitelaunch

In this article, we take a detailed look at today’s new GSM standard, electronic SIM, or eSIM, and talk about how it will affect today’s mobile devices.

We live in the age of communication. Computers, televisions, mobile phones and many other smart electronic devices do not fall out of the hands of many of us. In communication, channels that enable communication have become as important as the sender and receiver. Internet provider for our computer, messaging for social media organizations, home phone providers and mobile operators for our mobile phones …

All these providers and operators need to get to know their large number of customers and offer everyone the same service they pay for. While these different telecommunications areas operate in different ways, today SIM cards operators know their customers through. It can be small and various sizes and its original name ICC This semiconductor stack is used in many areas today. In addition to mobile phones, in the banking sector, smart home systems, even identities …

ICC (Integrated Circuit Card) basically a microchip. Made of plastic from polyvinyl chloride or from polyethylene terephthalate The nominal equivalent of these tiny circuits in mobile operators is SIM (Subscriber Identity Module / Subscriber Identity Module) cards we call.

Until today SIM cards While it was a very efficient and good technology, it is because everything is now gradually digitizing and these technologies were not taken into account when they were first developed. security risks started to emerge. Due to reasons such as the fact that it is difficult to change operators because of the physical need of a SIM card, thieves copying some SIM cards and commit crimes on behalf of innocent people, and security vulnerabilities in the tools used to identify SIM card subscriber information, technologies that could quickly replace SIM began to be considered. At this point my partner Our mobile phones are now waiting for us to be used in many other areas.

What is eSIM? What are the advantages?

eSIM, physically user replaceable SIM / ICC It is a technology developed to reduce the disadvantages and risks of the cards and at the same time provide many convenience to the users. “Embedded SIM” so “Embedded SIM” Called this innovation, in its simplest form, it refers to a tiny chip built into your phone. It is very useful in many places and we use frequently NFC Thanks to this tiny chip that works similar to technology, we will no longer have to physically change things to change operators.

Safer, More Practical

The information in the eSIM can be rewritten, deleted and you can change your mobile operator at any time with a small phone call. It is also possible to subscribe to any operator within minutes, as if opening an application account and start using it immediately.

eSIM, the organization that sets the standards of mobile networks (GSM sector) GSMA (GSM Association) and it is defined as a worldwide standard.

Apart from its usefulness, there is no physical card, so it is unlikely to be copied by attackers or thieves. In this respect, we can say that it is safer.

eSIM Increases Mobility

If we take a look at another advantage, eSIM technology is undoubtedly very profitable for both operators and phone manufacturers. Because, in the simplest, phone manufacturers are now on devices with this technology. physical SIM slot allocation not required. This area will be evaluated for different purposes and technologies in the coming years. However, operators will now avoid the cost of producing and distributing SIM cards.

IoT With the advent of e-SIM, an increase is expected in devices. We can now see smart fridges, watches, treadmills, cars and more, which do not need an ICC card but connected to the Internet, more widely in the future.

Disadvantages of eSIM Technology

Although it is a useful technology in many ways, many users may have difficulties because it is unconventional. We have the possibility to see devices that come with any operator subscription within the next time frame. This will undoubtedly challenge many people to choose the right operator and device.

Also let’s say you want to change your phone. Before eSIM, you could use your previous subscription by quickly inserting your SIM card into the phone you just bought, but unfortunately, you will need to contact your operator or install a new profile to be able to use your old subscription on the new phone.

In addition to all these, we have to abandon some of our habits. Most of us would save the numbers we recorded in the memory of our SIM card in case something happened to our phone, and in case of any problem, we would transfer the numbers to the new phone without much effort. Since we will no longer have a SIM card that we can physically record, we change our habits a bit and cloud backup We have to take advantage of their services.

eSIM Supported Mobile Devices

With the launch of e-SIM, many new devices introduced to the market support this technology. Some of these devices are:

  • iPad Pro
  • Apple Watch Series 3
  • Apple Watch Series 4
  • Apple Watch Series 5
  • Apple iPhone XS
  • Apple iPhone XS Max
  • Apple iPhone XR
  • Apple iPhone 11
  • Apple iPhone 12
  • Google Pixel 2
  • Google Fi
  • Google Pixel 3
  • Google Pixel 3 XL
  • Google Pixel 4
  • Google Pixel 4 XL
  • Google Pixel 4A
  • Samsung Galaxy S20
  • Samsung Galaxy S20 +
  • Samsung Galaxy S20 Ultra
  • Samsung Z Fold 2
  • Huawei P40
  • Huawei P40 Pro
  • Huawei Mate 40 Pro

In addition to the list Moto Razr Let us mention that the model also includes e-SIM support. There is already eSIM support for the Windows 10 operating system. So we can see computers using eSIM in the near future.

Will eSIM Eliminate Roaming Fees?

One of the things that many people who go abroad frequently complain about is due to the use made abroad. astronomical roaming charges the receipt. At the same time, if you are in an out of scope area, unfortunately you cannot use your number. my partner This eliminates this situation. When you go abroad, you can start and easily terminate subscriptions from regional operators that will meet your needs for a short time. So you get rid of astronomical bills.

Also, did you know that the size and quality of the SIM cards we have used so far, even the operator itself, have an impact on the battery life of your phone? Since there will not be a physical SIM card in e-SIM technology, battery life It will be longer in e-SIM supported devices compared to normal devices.

How will eSIM work in practice?

When using the e-SIM in your device, you will be able to choose between the two if you use it in the physical SIM additionally. At the same time, it is possible to make calls and send / receive SMS from both numbers while the device is in standby mode. All you have to do is change any of your device’s settings to default.

Some iPhone devices offer dual eSIM support. However, you cannot use both at the same time. You can choose one of the cellular network settings and start using that eSIM subscription.

How to Activate eSIM?

You can activate eSIM on your supported devices in two ways. The first method is to physically scan the QR codes you receive from your operator’s dealer, and the second method is to start using it through the mobile application, if your operator supports it.

For example, if you have a supported iPhone device, you can start using it by going to the “Cellular Connection” section from the “Settings” menu and scanning the QR code from the add section. In application supported installation, it will be enough to get your operator’s application from the App Store and add the relevant subscription from the settings menu after purchasing a subscription. However, don’t forget to define the e-SIM for mobile data connection as well.

Sample e-SIM subscription sold in Germany. Subscription is initiated by scanning the QR code on the card.

My ESI in Turkey

Turkey’s ESI m We can say that it has switched to technology very quickly. Currently available mobile operators all offer this technology to their subscribers. All you have to do Getting an eSIM compatible mobile device and applying to operators to use e-SIM technology. Even if you used a physical SIM card before, the possibility to switch without canceling your subscription is recognized by many carriers.

The Future of eSIM

Now that we live in the age of digitalization, we will begin to see e-SIM technology frequently at many points in our lives. Because the Internet of Things, the spread of smart devices and many remote controlled technologies are now planned to use eSIM to overcome physical barriers for connectivity. We can see more mobile and smarter devices, and perhaps even networked smart glasses by taking advantage of this technology. Who knows what else awaits us?
