What is an eSIM? Why should you get one?

An eSIM, or embedded SIM, is built directly into your phone’s hardware unlike a traditional SIM card, which is a small physical chip that you have to insert into your phone.

Think of it like a tiny, powerful companion who can do all sorts of magical things like being programmed with all the information and settings needed to connect to a cellular network. When you want to switch carriers, the eSIM simply updates its programming with the new carrier's information, without the need for a physical SIM card swap.

An eSIM also gives you the ability to keep multiple cellular plans and switch between them on the fly – allowing you to skip roaming charges and experience seamless connectivity even while crossing borders. 

Suppose you have a month-long vacation with stops in multiple countries. Imagine the sheer amount of paperwork and effort that would be needed to get a new local SIM card at each destination! With the holidayeSim Asia eSIM you can get connected in seconds and just keep recharging according to your needs.

It's a clever, convenient way to stay connected, without the need for a physical SIM card.

Is eSIM better for international travel?

Yes, eSIM is better for international travel than a physical SIM card as it enables you to save time and money by avoiding the hassle of finding and purchasing a local SIM card. With the eSIM Asia, you don't have to swap physical SIM cards when traveling to a new country or switching to a new carrier. 

This means you can save time and avoid the hassle of finding and purchasing a local SIM card or waiting for your current carrier to activate international roaming as the eSIM can be activated remotely, which means you can purchase and activate a new plan without leaving your home country. 

This is particularly useful if you want to have a local SIM card waiting for you upon arrival, or if you want to research and purchase the best plan in advance.

Furthermore, an eSIM can prove indispensable for those looking for secure ways to connect without risking local Wi-Fi. Although Asia is a beautiful destination with nearly unlimited things to do and explore, it may not be the best when it comes to cybersecurity for travelers. It is up to you to keep your personal information safe and secure.

Considering how risky public Wi-Fi can potentially be, your best bet at staying safe and secure is to just be on your mobile data. After all, with unlimited data offered by your Asia eSIM, we can’t imagine you running into the scenario of running out of data and then being forced to connect to Wi-Fi out of necessity.

eSIMs use a process called remote SIM provisioning (RSP) to encrypt communication between the device and the network. This makes it harder for attackers to intercept and eavesdrop on your calls or data. 

RSP is the process that allows the eSIM to be programmed over-the-air by the mobile network operator. RSP uses a secure and encrypted communication channel to exchange information between the device and the network. This communication is protected by a secure session key that is unique to the device and the network.

During the provisioning process, the eSIM is initialized with a set of encryption keys and security parameters that are unique to the device and the network. These keys are used to encrypt and authenticate communication between the device and the network, making it harder for attackers to intercept and eavesdrop on your calls or data.

The encryption keys used in RSP are generated and managed securely by the network operator. This means that the keys are not stored on the device or in the eSIM, but are securely stored in the network's infrastructure. This helps to prevent attacks such as SIM cloning or SIM swapping, where an attacker tries to copy or replace a SIM card to gain access to the user's phone number and personal information.

Furthermore, our Asia eSIM includes a set of security features that protect against attacks, such as tampering, reverse engineering, or unauthorized access. For example, eSIMs have a secure boot process that ensures the integrity of the eSIM software and prevents unauthorized modifications. They also use a set of secure access protocols that prevent unauthorized access to the eSIM and protect the user's privacy.

The holidayeSim Asia eSIMs use strong authentication methods to verify the device and the user. This reduces the risk of SIM cloning or other attacks that can compromise your personal information.

Finally, eSIMs are much better for the environment, unlike physical SIM cards which can contribute to electronic waste. With an eSIM, you can reduce your environmental footprint and help protect the planet. Physical SIM cards are made of plastic and require significant resources to manufacture and distribute. 

Although physical SIM cards are small, but when multiplied by the billions of devices in the world, they can create a significant amount of electronic waste. eSIMs, on the other hand, are embedded in the device and do not need to be replaced or disposed of separately. 

Physical SIM cards also require shipping and packaging, which can contribute to carbon emissions and waste. eSIMs, however, can be programmed remotely, which reduces the need for shipping and packaging.

Does eSIM drain your battery faster?

No, eSIMs do not drain the battery faster than physical SIM cards. In fact, since eSIMs are embedded in the device and do not require a physical SIM card slot, they can actually help conserve battery life by reducing the amount of power needed to run the device.

There are several factors that affect the battery life of a device, including the screen brightness, the number of apps running in the background, the network connection, and the type of communication being used (voice, data, or text). However, the use of eSIMs does not have a significant impact on battery life, as the eSIM chip itself consumes very little power.

In fact, the holidayeSim Asia eSIM can actually help conserve battery life in certain situations. For example, eSIMs can allow for more efficient network switching and roaming, which can reduce the amount of time that the device spends searching for a signal and consuming battery power. 

eSIMs can also allow for more efficient use of mobile data by providing access to multiple carrier profiles and allowing users to choose the most appropriate plan for their needs.
