Excess And E-SIM Shortage: Facilitating Devices Connected To Networks, But...

YOGYAKARTA SIM card (Subscriber Identification Module) is a small card in a mobile phone that stores information on mobile phone users. Currently, a number of cellular operators in the country have provided more sophisticated SIM cards as e-SIM (Embedded Subscriber Indentification Module). So, what is eSIM? What are the advantages and shortages of eSIM? Here's the explanation.

e-SIM is a moving house that is permanently embedded in the motherboard or smartphone machine.

Quoted from PcMag, e-SIM allows you to change wireless operators, data or service packages via software.

On e-SIM devices, in general, you can open a menu or take a photo of the QR code to quickly change the operator or service package. You don't have to go to the store to buy a SIM card or tamper with a small chip.

With e-SIM, you can also use two different lanes on the same device, such as a home and office path, or switch between different packets depending on where you are.

This means, e-SIM will give you more flexibility in managing the service package provided by the provider. Fully activated e-SIM devices allow you to add a second package, while you are roasting or if you want a separate work channel.

Currently, e-SIM services are only available in certain flagship smartphones, such as Apple, Samsung, Huawei, and Oppo.

What Are The Excess And Lacks Of E-SIM?

Summarized from various sources, here are some advantages of e-SIM over regular SIM cards:

Mobile operators can optimize the level of security of e-SIM user data through strengthening encryption and increasing the security of credential data. Thus, user privacy is well maintained so as not to leak into irresponsible parties.

The advantage of e-SIM is compared to the next physical SIM card, which is that its use is more practical. This is because e-SIM has been permanently embedded in the smartphone machine. So users do not need to buy physical SIM cards separately to access the internet network.

If a physical SIM card can store the mobile number in the card storage contact, then e-SIM will save the contact number into the cloud system.

That way, users don't need to worry about losing the contact number if the SIM card is lost or damaged. The reason is, the contact number will be directly saved to the cloud.

If users change phones, they can also download data without being scattered at all.

The last advantage of e-SIM is to make it easier for smartphone manufacturers to create water-resistant devices. This is because they no longer need to present physical SIM card slots on smartphones.

While the lack of e-SIM compared to standard SIM cards, among others:

Smartphones that are lined up with e-SIM cannot be operated directly. Users take about 15 minutes after the scanning process. Unlike physical SIM cards that can be activated immediately when put on a mobile phone.

Since the eSIM is embedded in a smartphone machine, e-SIM users will continue to be active on their operator network and easier to track.

Unlike the standard SIM card, users only need to remove the SIM card from the slot contained in the smartphone to prevent cellular network from tracking their whereabouts.

Originally, e-SIM was very safe because data could not be placed on other devices programmed with verification. This condition will be a hassle for people who have malicious intent.

However, you need to worry if the bad people are the operators. An evil operator can sell the information it has to data thieves.
