eSIM - what is it? The new SIM card simply explained

The eSIM, which is used for example in the iPhone Xs and the Appel Watch 3 and 4, has recently been launched. But what is it exactly and what is the difference to conventional SIM cards? In this practical tip, we explain it easily understandable.

What is an eSIM? Easily explained

• In contrast to a normal SIM card, an eSIM is permanently installed in a device. It can therefore not be replaced. The "e" in eSIM comes from the English word "embedded", embedded or integrated in German.
• An eSIM uses the same specifications as normal SIM cards. Therefore, they are compatible with each other and it makes no difference which SIM type you use.
• The decisive advantage of an eSIM, however, is that the SIM chip can be rewritten by your provider. So if you have signed a new contract, you no longer have to wait for your new SIM card. In addition, problems with incorrect sizes of SIM cards no longer occur. In this way, switching providers is accelerated and simplified.
• The eSIM also makes sense for smartphone manufacturers. Since the eSIM is built into the device, it is no longer necessary to install error-prone card mechanisms.
• The dark side of the topic is that there are currently very few providers for eSIMs. This is also due to the fact that some mobile operators reject this new technology.
• You can currently get eSIMs from Telekom and Vodafone. You need it for example for the iPhone Xs and the Apple Watch Series 3 and 4.

Therefore, the breakthrough of the eSIM is delayed

It will be a while before the eSIM arrives on the German market. Until then, we still have to deal with annoying problems such as the wrong SIM size. In the next practical tip, you will learn how to cut SIM cards yourself.
