What is an eSIM: Detailed Explanation 2024

SIM, MicroSIM, nanoSIM… Technology evolution does not stand still, so now we are entering the era of virtual SIM cards that are built right into the motherboard of a smartphone. The new standard allows you to abandon the physical SIM card. How convenient is it, what are the features of this functionality, and in what situations might an eSIM be useful? Let’s take a look in this article.  

Note! If you need an eSIM, you can use providers such as ESIM-Man, Airalo or Ubigi. They offer over 2000+ different tariff plans from 15 different providers in 172 countries and destinations.


What is an eSIM?

First of all, it should be understood that eSIM is not an electronic SIM card, as many people think. It stands for embedded SIM. That is, its key feature is that it is inside a smartphone or other electronic device.

Few people know, but a classic SIM card is not just a piece of plastic, but a full-fledged computer with a processor up to 10 MHz, non-volatile memory and even an operating system. Such a computer is powered by the device in which it is embedded.


History of eSIM Appearance

Representatives of mobile operators began to talk about the use of eSIM technology in 2010. And the first user device with it appeared in 2016. It was a smart watch Samsung Gear S2 Classic 3G.

In 2017, the feature appeared on the Apple Watch Series 3, and in 2018 – on the iPhone XS, iPhone XS Max and iPhone XR.


3 Cases When an eSIM Will Be Useful

  • The need for a second SIM card.If Android owners have everything more or less simple: they go to the store, buy another SIM-card and insert it into their Dual SIM smartphone, then the owners of iPhones can not boast of this. In this situation, the best solution is to use eSIM, which allows you to activate up to 5 phone numbers at the same time. 
  • Traveling to another country. For example, you leave your home operator, and for traveling abroad activate eSIM to avoid huge expenses for international data roaming and have internet wherever you are.If you want to buy an eSIM on the spot, use the list of eSIM operators from the ESIM-Man provider.
  • So you don’t have to take your phone for a run. At the moment, the most interesting use of an eSIM is internet on the new Apple Watch to stream music, make calls, reply to Telegram, but not to take your phone with you.


Flagships & Budgets: Which Devices Support eSIM

Today, such technology is more in the testing phase in an attempt to see if it will become popular with users. That said, many leading companies have already launched the feature. Among the devices with eSIM support today: 

  • iPhone XS to 13 mini; iPad Pro 12.9 to Apple iPad Air.
  • Galaxy S20 to Galaxy Z Flip3.
  • Pixel 3, 3a, 3 XL, 3a XL and newer.
  • Huawei P40/P40 Pro, ANA-N29, ELS-N29. 

Not only smartphones support such technology. The embedded chip is present in the Galaxy Watch 4 Classic LTE and Apple Watch.



So, eSIM is a future that is slowly becoming a reality. Every year more and more devices will have the technology built-in and more operators will support it. If you are not yet ready to completely abandon the usual plastic SIM cards, but your smartphone supports the virtual analog, it makes sense to try installing eSIM as an additional one. This way, you will be able to evaluate its capabilities and advantages in practice.
