eSIM : Invisible SIM card

Reading Time: 2 min

SIM card – without which a smartphone is not smart anymore because we can’t call or use Internet without a SIM card.



eSIM is nothing but an ” Embedded SIM card “which is not visible physically and does not require physical swapping by us.

It is a global specification empowered by GSMA which enables remote SIM provisioning of any cell phone.


As we all know that Apple has turned to eSIM to add connectivity to iPhone XS and iPhone XS Max. Also, Google’s Pixel 2 supports eSIM but that was only in US for Google’s Project Fi.

eSIM also needs to be supported by the network or carrier and should be enabled by them. So if you are planning to buy an eSIM compatible phone then you’ll need to choose an eSIM compatible network too for second SIM support.


In this concept, you will be able to change the Carrier or network without having to get a new SIM.

We will also be of no need to cut that extra plastic to adjust the size according to our phone, thus improving reliability.



It also help make devices smaller not mainly for phones but for wearables like iWatch Series 3 in which Apple successfully made the product much slimmer than it’s previous Series by using this technology.

It makes easy to store Multiple Operators Profile in eSIM.

The another good thing is that using eSIM we will be not charged with international roaming bills and also connectivity is guaranteed.

It also enables data plan purchase and enabling it without Network Connection i.e., via Smart Bootstrap.


But currently the only hand-picked couple of countries uses this technology and they are:-

  1. Croatia
  2. Canada
  3. Austria
  4. Germany
  5. Hungary
  6. The Czech Republic
  7. India
  8. US
  9. UK
  10. Spain


But also there are very few Network Carries that supports eSIM but soon the technology of eSIM will take over the SIM card technology and will be improving the world’s capabilities.
