eSIM 5 Principles and Advantages of eSIM, helping you to easily access the Internet
- Published on
With the progress of science and technology, cell phone communication technology is also evolving. eSIM (embedded SIM card) as a new type of digital SIM card, is gradually replacing the traditional SIM card. In this article, we will introduce the definition of eSIM, the difference between eSIM and traditional SIM card, the working principle, as well as the matters to pay attention to in the process of use.
What is eSIM?
eSIM stands for “Embedded SIM Card”. It is a digital SIM card that is built into a device and allows users to connect to a mobile network without the need for a physical card. Unlike traditional SIM cards, eSIM allows users to activate and manage network services by downloading the operator's profile.
Features of eSIM
- No physical card: eSIM does not require the insertion or removal of a physical card, making it easier for users to manage their network connection.
- Remote Management: Users can change carriers or packages at any time over the network without having to go to a physical store to replace the SIM card.
- Multi-Network Support: eSIM can store profiles for multiple carriers and users can switch between them at any time as needed.
What is the difference between an eSIM and a SIM card?
Although both eSIM and traditional SIM cards are used to connect to mobile networks, there are many significant differences between them.
1. Physical form
- Traditional SIM card: A small plastic card that the user needs to insert into the SIM slot of the device.
- eSIM: It is a digital chip embedded inside the device and the user does not need to handle the physical card.
2. Activation Methods
- Traditional SIM card: After purchasing a SIM card, users need to manually insert it into the device and activate it.
- eSIM: Users can download and activate the network configuration remotely by scanning the QR code or entering the activation code.
3. Flexibility
- Legacy SIM: Users need to replace the physical card when changing carriers.
- eSIM: Supports multiple operator profiles, users can switch at any time without changing cards.
4. Environmental Factors
- Traditional SIM card: Plastic resources are consumed during production and use.
- eSIM: Reduces the need for physical cards and is more environmentally friendly.
What is the principle of eSIM?
eSIM works on the basis of a technology called Remote SIM Provisioning. This technology allows the user to download and activate the operator's profile over the Internet. The main steps are as follows:
- Downloading the configuration file: After selecting the operator, users can download the eSIM configuration file by scanning the QR code or entering the activation code.
- Activate network service: After downloading, the device will automatically activate the configuration file, and the network connection will take effect immediately.
- Switching Operator: If users need to change operator, just download the new configuration file and the old one will be replaced.
Which does the phone prioritize?
When both a traditional SIM card and an eSIM are present on the device, the phone will prioritize the network connection based on the settings. In general, the phone will prioritize the following order:
- eSIM: If eSIM is activated and provides a valid signal, the device will prioritize connecting to eSIM.
- Legacy SIM: If eSIM is not activated or there is no network signal, the phone will automatically switch to the legacy SIM.
Recommendations for use
When traveling, it is recommended that users activate their eSIM in advance, not only to avoid high roaming charges, but also to ensure a fast connection to the network at the destination.
Will the eSIM option charge me if I run out of traffic?
When using an eSIM service, users usually need to purchase a specific subscription, which has a limited amount of traffic. So what happens when there is not enough traffic?
1. Traffic management
Most eSIM packages set a certain traffic limit. Once the user reaches the limit, data service may be suspended until the next billing cycle starts or the user purchases additional traffic.
2. Charges for Excess Traffic
In some cases, if the package settings allow for excess traffic usage, the operator may charge additional fees if the subscriber exceeds the package traffic. These charges are usually higher than the cost of the traffic included in the subscription, so users should read the relevant terms and conditions carefully when choosing a subscription.
3. Transparency and choice
Many operators provide clear traffic usage reports, allowing users to view their used and remaining traffic in real time. This transparency allows users to better manage their data usage and avoid unnecessary charges.
Can I have more than one eSIM installed on my phone?
Yes, many modern smartphones support the installation of multiple eSIM profiles at the same time. Users can switch between different eSIMs as required, making it easy to switch to a local eSIM data package when traveling.
Advantages of multiple eSIMs
- Flexibility: Users can choose the right network service according to different needs and locations, avoiding high roaming charges.
- Convenience: Users do not need to replace the physical SIM card and can switch network connection with simple operation.
Applicable Scenarios
When traveling internationally, users can keep their local operator's eSIM configuration and download the destination's eSIM at the same time, so that when they arrive in a new country, they can use the local network immediately.
Advantages of choosing eSIM while traveling
1. Cheap
With an eSIM, users can purchase local data packages directly, avoiding costly roaming charges. In many countries, the cost of eSIM data traffic with local operators is often lower than traditional roaming services, which is especially important for frequent travelers.
2. Fast Internet speeds
By using a local operator's network, users can enjoy faster speeds and a more stable connection. Whether they are in the city center or remote areas, they can have a good internet experience, which is convenient for users to surf the internet, socialize and get information at any time.
3. Flexible Package Options
eSIM provides a variety of package options, users can choose freely according to their own needs, to ensure that they stay within their budget when traveling. For short or long distance travel, users can choose the right package to meet different data needs.
