What Is ESIM: Causes Of Poor Mobile Signal And How To Solve Them

In this article, you will learn about the features of using eSIM, as well as the most effective ways to improve communication.

With the development of mobile technologies, new opportunities for users are emerging, and one such innovation is eSIM technology. eSIM technology makes it easier to connect to a mobile network, but problems with a poor signal can still occur. The reasons may be related to coverage or technical failures. With the plans to 2G switch off, UK by 2033, it is worth thinking about ways to improve mobile coverage for the communication standards used in advance. 

What is eSIM And Where Is It Used?

eSIM is a mobile communications technology that is an embedded chip in a device and replaces a physical SIM card. It allows users to manage their mobile connections without the need for replaceable SIM cards.

eSIM performs the same function as a traditional SIM card.

Key features of eSIM:

• Embedded technology. The eSIM is a software SIM card embedded in the device. It can be activated and configured using software.

• Remote management. Users can remotely change their mobile connections without having to physically replace the SIM card. This is convenient for switching between operators or when using different mobile devices.

• Support for multiple profiles. The same eSIM can support multiple profiles for different operators or different services.

• Space saving. Since the eSIM is embedded directly in the device, there is no need to allocate space for a physical SIM card. This is especially important for compact devices such as smart watches or headphones.

The eSIM card is used in various types of devices, including some models of cars. The technology is actively developing. Here are some examples of places where eSIM is used: 

• smartphones and tablets;

• wearable electronics (smart watches, fitness trackers, etc.);

• laptops and tablets with LTE;

• smart sensors, smart gadgets for home, etc.; electronic devices for traveling (for example, modern routers for traveling).

How Does eSIM Work?

eSIM technology is gaining popularity due to its convenience and flexibility. It allows you to do away with physical SIM cards, providing easier connection to mobile operators and the ability to quickly switch between tariffs. Let's take a look at how eSIM works:

1. Activation and programming. A device that supports eSIM comes with a pre-installed eSIM chip. The user activates his mobile connection through the web portal of the telecom operator.
2. Receiving a profile from the operator. The operator sends a digital profile (connection information) to the built-in eSIM chip in the device.
3. Installing a profile. The device receives and installs a profile, which includes subscription information, authentication, and other parameters necessary for connecting to the network.
4. Multiple profiles. Some devices with eSIM can support multiple profiles, allowing users to switch between different operators or connections.
5. Connection management. The user can remotely manage their mobile connections via the operator's web portal or special applications without touching the physical SIM card.
6. Operator change (optional). The user can change their operator without having to change the physical SIM card. Thus, eSIM provides more flexible management of mobile connections, eliminating the need for interchangeable SIM cards. It also contributes to improving the user experience of modern devices.

Reasons For Poor Mobile Connection When Using eSIM

Despite the advantages of eSIM, the user may encounter the same communication problems as when using a traditional SIM. The reasons for the unavailability of a mobile signal can be divided into several key categories:

1. Geographical factors. The user may experience problems with mobile communication in remote or hard-to-reach areas, including outside the city, in the forest, in the mountains. This is due to insufficient coverage of cell towers.
2. Architectural barriers. Communication problems may occur not only outside the city. Thick walls of buildings, underground spaces, elevators, and structures with metal structures also significantly reduce the level of the mobile signal.
3. Network congestion. In areas of large crowds of users, for example, at stadiums or festivals, the mobile network can often be overloaded, since too many users are connected to it at the same time.
4. Technical problems of the operator. Failures on the mobile provider side, such as equipment repairs, temporary outages, or network upgrades, can also result in a lack of signal. In this case, the operator notifies users via SMS, news on the website, or social networks.

Booster as a Means to Improve Mobile Signal

If you regularly experience problems with your mobile connection for any of the above reasons, then installing a booster can be an effective solution. A mobile signal booster is a device that amplifies a weak signal and improves the quality of communication in areas with poor coverage, which is especially important in case of a 2G turn-off. It works on the principle of receiving an existing signal from the nearest mobile tower, improving it, and transmitting it to the user's device. It consists of several components: an antenna to receive the signal, an amplifier to amplify it, and an internal antenna to transmit the amplified signal to your device. 

A booster is especially useful in places with hard-to-reach communication zones, such as underground floors, buildings with thick walls, or remote areas. With the help of a booster you can improve the signal of any mobile operator including O2, Vodafone, Virgin, etc.

Wrapping It Up

Mobile signal problems for users can be caused by many factors, from geographic location, and obstacles such as mountains and forests, to technical problems. The use of modern technologies helps to improve the mobile experience. For example, eSIM helps to simplify the connection and increase the flexibility of using mobile services, and boosters improve the connection where the signal is too weak. Given the plans to switch off 2G in the UK by 2033, it is important for users to think about using boosters that support 4G and 5G now. If you are looking for a reliable service provider to improve mobile communications with boosters, we recommend paying attention to UCtel. The company provides services to boost mobile signals of such popular British operators as Tesco, O2, Virgin, Vodafone, and others. In addition, the company provides services for the deployment of private 4G and 5G networks.
