Many people whose work is directly dependent on phone calls, the Internet, or traveling abroad face problems. These include high roaming fees, multiple devices to keep an eye on, or constant trips to centers to change operators. Every phone user certainly knows what a SIM card is. However, more and more often one hears about its virtual counterpart. Currently, there is a lot of talk about the fact that eSim cards will eventually displace their physical counterparts. Today we will tell you in more detail what a digital SIM card is and how it can help you.
How eSIM Technology Simplifies Managing Multiple Numbers
From a technical point of view, a SIM is just a special type of microprocessor card with a small amount of memory built into it. You can store a small amount of saved information, for example, in contact books. The advantage of this solution is that, in the case of a phone replacement, we can transfer all the information that is important to us from one device to another by removing the card and moving it.
The eSIM card has no physical equivalent. It is virtual but provides the same functionality as its physical version. In this case, you do not have to worry about accidental damage to the card, and everything is done remotely. This means that when buying a new phone and choosing an offer from one of the operators that support digital SIM Cards, you do not even have to go to the salon to buy its physical equivalent. Activation can be done from your smartphone. It is worth mentioning, however, that not all devices support this particular technology. It must be a phone with a special module that is permanently built in.
How eSIM works
First, you need a device that supports virtual SIM card technology.
The principle of operation can be compared with the NFC chip when you pay for purchases by applying a smartphone to the terminal. Money is debited from the account, but physically, you do not need to have a card from one or another bank. The phone stores data about it.
To fully use an eSIM card, despite being built into a smartphone or other device, the technology must be supported by the mobile operator and provide eSIM-related services.
How to setup an eSIM
The easiest way is to install a dedicated application. You can easily use your eSIM card by installing the Yesim app from the App Store or Play Market. So in the Yesim application, you can select a country and an operator, connect the data plan you need, and use their services. There is also a VPN in the application, and the privacy policy and security will keep your data safe.
A digital SIM card allows you to set up a carrier and plan abroad to help you stay in touch with family or colleagues using your virtual phone number from all over the world. Since your virtual SIM card has information about all mobile operators, it only takes one click to change your data plan or your company, for example. This is a feature that fans of traveling abroad will appreciate because they saving money with eSIM without losing their mobile number or risking a huge negative on their account.
Home and work
Options for using two numbers in eSIM
- One number is used for workers and the other for personal needs;
- While staying abroad, the data plan of the local operator is used;
- One plan is used for voice and the other for data.
Both phone numbers can be used to make and receive voice and FaceTime calls and to send and receive iMessage, SMS, and MMS messages.
Summing up all of the above, we can certainly say that the eSIM card is the future of mobile communications, which will make our lives much more convenient and cheaper. Separating work and home will become much easier, and using multiple data plans and operators is an easy but very profitable process.
