What is eSIM?

What is eSIM and why is it the future of mobile communications?
When it comes to the advancement of mobile technology, we all think of internet speeds and phone features, but a major change is happening behind the scenes: eSIM. This new technology will gradually replace physical SIM cards and change the way we connect to mobile networks.
What is eSIM?
The word eSIM stands for "Embedded SIM". Unlike regular SIM cards that are placed inside the phone as a small plastic card, eSIM is a digital and internal chip that is located directly on the device's motherboard. This chip stores information about the mobile operator and can connect to different networks without changing the physical SIM card.
Why is eSIM important?
With the increase in international travel and the need for users to quickly change operators, the presence of e-SIM acts like a revolution. The user can connect to the new network in a few seconds just by scanning a QR code or entering operator information.
Advantages of eSIM
Ease of use: You no longer need to cut or insert the SIM card.
• Saving space: new phones can be designed more narrowly.
• More security: The physical SIM card is no longer stolen or lost.
• Quick change of operator: especially useful for international travelers.
Support for multiple numbers: Some phones allow multiple eSIM profiles.
Disadvantages of eSIM
Despite the benefits, eSIM still has limitations:
• Not supporting all operators in all countries
Difficulty in transferring e-SIM from one phone to another
• The need for newer phones that support this feature

Comparison of eSIM and physical SIM card
To better understand the differences, see the table below:
eSIM in Iran and the world
In many developed countries such as America, England and Germany, e-SIM is expanding rapidly and major operators support it. In Iran, this issue has not yet been fully implemented, but it is expected that operators will move towards this technology in the near future.
How to activate eSIM?
Check that your phone supports e-SIM.
• Get a QR code or activation code from your operator.
• Enter the phone settings and open the Cellular or Mobile Data section.
• Select Add eSIM or Add Cellular Plan option.
• Scan the QR code or enter the information manually.
• Your profile will be activated and you can use it immediately.
Is eSIM the future of SIM cards?
Experts believe that in the next few years, most phones will only use e-SIM and physical SIM cards will be a thing of the past. This change is similar to removing the headphone jack or CD in laptops. At first there is resistance, but eventually everyone moves towards the new technology.
Applications of e-SIM in daily life
• For travelers who go to different countries and need fast and cheap internet.
• For those who have several different lines (for example, a business line and a personal line).
• For Internet of Things (IoT) devices such as smart watches or tablets.
