What is an eSIM?

The Embedded SIM – or “eSIM” relates to a new standard being promoted by the GSMA – the association that represents network operators worldwide.

It will come in the form of an integrated SIM chip, that cannot and will not need to be removed from a device. This is something that electronics manufacturers are also keen to adopt for connected items around the house as part of the Internet of Things (IoT).

The information on it will be rewritable by all operators, meaning that a user could decide to change operator with a simple phone call (Depending on their agreement of-course). A new SIM will not be required, there should also be no time delay in switching the e-SIM to its new purpose/provider. There will also be no physical swapping over required by the user.

The benefit of a smaller SIM for gadget makers like Apple and Samsung is obvious, it enable them to make their devices smaller and slimmer. There are other eSIM benefits also:

  • The eSIM can reduce the chance of water, dust and other bad things that can get inside your phone via the SIM card slot, as your phone, tablet, smart watch or other device will no longer have one.
  • Fitting an eSIM inside a phone will enable device makers to shrink the size normally swallowed up by regular card SIMs by 90 percent.

Both Apple and Samsung are on board so we could well see an e-SIM in the iPhone 7 or the Samsung Galaxy Note 6 this year.
