eSIM technology: how it works
[ad_1]
The expected iPhone 15 line will be equipped with larger capacity batteries. The increase will reach 18%. Due to this, the case will become a little thicker. Increased processor efficiency means greater autonomy.
It is also reported that Apple may abandon the SIM card slot in new smartphone models. Now the priority is eSIM technology. Let’s consider how it works and what advantages it gives.
How eSIM works
If you want to switch to another operator, you will have to leave your home and buy a physical SIM card. And using a single number on a watch, smartphone and refrigerator is possible, but complicated.
A virtual card simplifies everything. It is located in the hardware of the mobile device. There is no need for a physical card.
The built-in chip in an eSIM-compatible device allows you to use up to 20 profiles with different numbers and tariff plans. Now the card is available not only in smartphones, but also in household appliances, smart watches and cars.
If we compare a physical and a virtual instrument, then in the first case, programming for only one operator is involved. It will not be possible to change the basic information from the factory in the map.
To change the operator, a new SIM is required. The virtual tool is designed to simplify the process. The change of national or foreign service provider occurs thanks to programmatic actions.
Main advantages
It becomes much easier to get the necessary services from a mobile operator. Some advantages of this technology:
- If you lose your phone, you don’t need to ask for a physical SIM card.
- Simple change of tariffs and mobile operators. The virtual map includes information about all service providers. Actions are performed quickly and simply.
- Data recovery in case of loss. Information is not stored on the mobile device, but on the server. To restore, you only need to transfer the data to a new terminal.
- Always in touch while traveling. An important advantage of eSIM is the ability to use it as a MultiSIM. Allows you to share the amount of data between different devices, including smartphones and tablets. In another country, it will not be necessary to change the national SIM card to a foreign SIM card in order to receive the required package of services.
- Environmental friendliness. So far, there is no effective method of completely recycling a physical SIM card. This means environmental pollution and the loss of a large number of valuable resources. eSIM makes it possible to reduce the use of plastic and the consumption of raw materials necessary for the production of the information carrier.
When comparing physical and virtual devices, it is better to give preference to the second option.
Additional advantages
The use of virtual sims is beneficial to manufacturers and network operators. Less paperwork for the service provider. No need to worry about providing the user with a SIM card.
A virtual device simplifies everything. In the future, manufacturers will not have to think about slot placement.
For those who travel abroad, roaming loses its meaning. This allows you to save money. Roaming Internet is an expensive pleasure. With eSIM, the use of services becomes more economical.
Although the technology is not supported in all countries, it is developing rapidly. The starter package for virtual card activation is sold on operator websites.
