Modern communication technologies continue to evolve, providing users with more convenience and flexibility in communications. One such innovation is eSIM, an embedded SIM card that allows users to connect to operator networks without the need for a physical SIM card. This is especially relevant in the context of the growing popularity of remote work, travel, and new solutions, such as private 5G networks that offer even greater control and productivity in the field of communication. In this article, you will learn about the benefits of using eSIM.
What is eSIM?
An eSIM, or embedded SIM card, differs from a traditional SIM card in that it does not have a physical form. A traditional SIM card needs to be physically replaced when changing a mobile operator, while an eSIM is integrated directly into the device.
This means that an eSIM can be used to work with different mobile operators without having to change anything. This makes managing your mobile connection much easier and more convenient.
How Does eSIM Technology Work?
The principle of eSIM is quite simple. For example, with an eSIM, a user can activate their new electronic card via a special QR code or a mobile operator application.
Once the mobile operator profile is loaded onto the eSIM, the device is ready to use. Switching between operators is also easy: just scan the new QR code or use the application to download the profile of the new operator. This greatly simplifies the activation process.
Advantages of eSIM
eSIM technology has certain advantages:
- Simplified activation and switching between operators. You can instantly activate a new SIM card or switch between tariffs – and you don’t have to go to the store to do it.
- Saving space in devices. The lack of a slot for a physical SIM card allows manufacturers of smartphones and other devices to use this space to improve other features (for example, increase battery capacity or add additional sensors).
- Protecting the user’s number if the gadget is lost. If a person loses a smartphone, the number associated with the eSIM can be easily restored without replacing the SIM card.
- The ability to use multiple numbers. Many devices allow users to use multiple eSIM profiles. This is convenient for travelers and those who often change operators.
- Eco-friendliness. Since eSIM does not require the production of a physical plastic card, this makes it a more environmentally friendly option compared to traditional SIM cards.
These are far from all the benefits that eSIM provides. For example, with a virtual card, the user can use a single number in different countries without roaming, as well as save money and maintain the privacy of his data.
How to find out if your phone supports eSIM
You can check your smartphone for eSIM support in several ways:
- Check the documentation for your smartphone, perhaps there is information about eSIM support even on the packaging.
- Visit the manufacturer’s website. You can find detailed specifications of the device on the official website.
- Contact support. If you have questions about eSIM and support for this technology on your device, you can contact your operator’s technical support.
- Among the popular models that support eSIM are the Apple iPhone (starting with the iPhone XS), iPad, and Google Pixel, as well as many devices from Xiaomi and Samsung.
How to Connect eSIM
Although the principle of operation of a virtual SIM card is no different from a physical one, the method of setting up and connecting here is completely different. In different smartphones, this is arranged differently, but the general principle is the same.
First, the user downloads the application of the operator or bank that provides eSIM support, then draws up an agreement (send a scan of your passport or go through identification using biometric data), and at the end selects a tariff and starts using it.
After this, the SIM card settings are downloaded to the user’s smartphone. In the future, the user only needs to choose which of the SIM cards will be the main one or will be responsible for calls/Internet, and whether it will support automatic switching between SIM cards for the best quality of communication.
By the way, all iPhones support quick transfer of a virtual SIM card from one device to another without having to delete the eSIM profile from the old phone and reinstall it on the new one.
If you don’t want to deal with installing applications and settings, you can ask for help from specialists who will help you connect a virtual SIM card.
How to Solve Mobile Connection Problems When Using eSIM
Just like with traditional SIM cards, users may have problems accessing mobile communications, especially in densely populated areas or, on the contrary, outside the city.
To improve mobile Internet when using eSIM, you should use the same methods as when using a traditional SIM card. First of all, when choosing an eSIM, you should choose an operator with the best coverage in your region. If you are in an area with a weak mobile signal, the best solution is to install a booster. This device amplifies a weak signal from a base station, improving not only voice communication but also the speed of mobile Internet. Modern boosters support work with several frequencies, including 5G, and can serve several devices at once, providing comfortable use of the Internet for the whole family or team.
Final Thoughts
eSIM technology provides modern smartphone users with many advantages, including convenient connection management and the ability to quickly switch between operators. When combined with solutions such as private 4G and 5G networks, eSIM becomes a tool for creating a highly efficient and flexible communication system. However, the stability of the mobile Internet still depends on external factors, and additional devices such as signal boosters can be used to eliminate them. If you are interested in using custom 5G networks or improving communication with boosters (for Vodafone, O2, Three, Virgin, etc), we recommend UCtel.
