[br][br]An eSIM is an electronic SIM card. As the name suggests, it will replace the physical, plastic SIM card all current smartphones use with a virtual embedded equivalent that cannot be removed. (A related new embedded SIM technology, the iSIM, has recently been announced by ARM, but this will initially be tied to tiny Internet of Things sensors and isn’t really relevant yet in the general consumer space).[br][br][br]

[br][br]The first time we came across this hardware in person was in the samsung gear s2 3G in 2016. However, it was the Apple Watch 3 that really brought eSIM technology into the spotlight. The eSIM can be found on the Pixel 2 smartphone. [br][br]On the iphone xs and iphone xs Max the idea behind the eSIM is to enable the first dual-SIM iPhone. Rather than adding an extra slot for an additional nano-SIM. You’ll be able to subscribe to a network using your phone just like you do on cellular-enabled iPads with the Apple SIM.[br][br][br]

[br][br]One of the benefits of an eSIM is that it’s absolutely tiny, just a small fraction the size of a nano SIM. This is what makes it so well-suited to ultra-compact gadgets like watches, which simply don’t have the room for a normal SIM.[br][br]An eSIM is non-removable and sits by other internal components. You don’t have to remove it, and it isn’t at risk of compromising any water resistance of a gadget’s shell.[br][br][br]

[br][br]With such an embedded standard, the idea is that you can switch to a new operator without having to insert a specific SIM card. It’s all done through software. [br]One of the most interesting aspects of the Watch’s eSIM is that it’ll share your iPhone’s number. You can think of them as part of the same connection. However, this also means it’ll only work with an iPhone – and that your iPhone and Apple Watch will have to be with the same network provider.[br][br][br]

[br][br]The future of eSIMS[br][br]The GSMA is the organisation that represents the interests of mobile operators around the globe, and it has announced a standard for this new kind of SIM.[br][br]Besides Samsung and Apple, AT&T, Deutsche Telekom, Etisalat, Hutchison Whampoa (owner of Three and soon O2), Orange, Telefónica (the current O2 owner) and Vodafone are also said to be on board.[br][br]The network data that a standard SIM card carries will be rewritable on future eSIM devices, so all you’ll need to do to change operator is make a phone call or two – rather like when you arrange to bring your phone number across to a new network now (though hopefully even easier).[br][br][br]

[br][br]Another advantage will be when travelling. It will be much easier to switch to a local network if you’re going to be spending any great amount of money abroad. [br]The other problem with physical SIM cards is that there are currently two or three sizes in play.[br]Have you ever tried swapping an iPhone for an Android phone, or vice versa? Very often, they use different types of SIM entirely. This necessitates the use of an ugly and flimsy plastic adaptor, or else an entirely new SIM, neither of which is ideal.[br][br][br]Source[br][br][br]
