The history of electronics development is closely connected with miniaturization. Almost everything, from processors to memory modules, decreases with development, including SIM cards. The initial ones resembled bank cards in size. The Mini-SIM era followed for almost 20 years before being succeeded by the Micro-SIM and Nano-SIM, and finally, by eSIM technology today. It allows you to do away with the physical “Sim card totally,” and in the case of a smartphone, it frees up more room for other parts.
Built-in SIM
Simply put, an eSIM (embedded SIM) is a SIM card that has been physically bonded onto the motherboard of a cellular device. Experienced users recall how each device had to be manually registered in the operator’s database at the beginning of mobile telephony. Do you really need to come back to the office to switch the operator or buy a new data plan?
Thankfully, you won’t need to. SIM stands for Subscriber Identity Module, but it is more than that. It has a 10 MHz processor, permanent non-volatile memory, controllers, and even its operating system. The SIM is powered by a smartphone. eSIM may function without a mobile network.
The data linked to the phone number and mobile network operator could not be changed on a traditional SIM card. Digital SIM allows you to make this setting repeatedly and even store several numbers simultaneously. Let’s tell you how it works.
eSim activation
You must obtain a unique QR code from your operator to activate a virtual sim card. The next step is to scan it with a machine that works with this technology. The necessary tariff can be added, and the card can be activated in the phone’s settings or the operator’s application.
You must remove the card settings from the old device’s memory if you need to switch the SIM device (for instance, after purchasing a new smartphone). The setup and activation processes on the new device will need to be repeated. The maximum number of eSIM activations is set independently by each mobile provider. This occurs roughly 100 times on average. You can find the exact figure from the operator or its official website.
It is important to remember that activation is only possible using a QR code, so you should be careful about its safety. In case of loss, you must contact your mobile operator again.
Connectivity
As we have already said, a virtual card can be connected remotely, without visiting communication stores. But in some countries, there are some peculiarities due to the peculiarities of the legislation that does not allow the connection of sim cards without presenting documents.
Safety in use
The issue of data security in the modern world is very relevant and essential for many users. eSIM technology has a high degree of data protection on the global market. But it should be borne in mind that all data is stored in the cloud. So there is always a chance, however small, that it can be hacked. In addition, if you lose the QR code, you risk it will fall into the hands of scammers and be used to access your card.
However, both of these probabilities are extremely small, and the risk of data loss is no greater than losing your Apple iPhone with a regular SIM card inside.
Replacing a plastic sim card or using dual sim cards
A plastic SIM card was designed to be entirely replaced by an electronic SIM card. However, in addition to its independent use, it is also possible that two SIM cards—an eSIM and a conventional one—will be installed on your phone. Different tariffs can be connected using this option. For instance, one tariff from esimway.com might offer convenient Internet access to deprive roaming, while the second might provide a sizable number of phone minutes.
True, it should be borne in mind that it will not work to activate both cards simultaneously. You have to use them one by one.
