Can an eSIM Be Removed? An Easy Explanation for Beginners

When considering switching from a physical SIM to an eSIM, many people often wonder whether an eSIM can be removed and whether installing one will affect the SIM they are currently using. This concern mainly comes from confusing the act of removing a traditional SIM with deleting an eSIM on a phone. The article below will help you understand what an eSIM really is, how to manage it, and the important things to know before using one.

What is an eSIM and how is it different from a physical SIM?

eSIM(Embedded SIM) is a built-in electronic SIM integrated into the device, allowing users to activate a mobile plan without inserting a physical SIM card. Instead of removing and inserting SIM cards as before, an eSIM is managed directly through the phone’s settings.

To help you easily visualize the difference between an eSIM and a physical SIM in real use, you can refer to the comparison table below:

Criteria	eSIM	Physical SIM
Form	Built-in electronic SIM integrated into the device	Removable SIM card, inserted into the SIM slot
Activation method	Activate the plan via QR code or system settings	Activate by inserting the SIM into the device
Device management	Manage, turn on/off, or delete directly in settings	Manage by removing or replacing the SIM
Ability to change plans	Change plans through settings (depending on the provider)	Need to replace the SIM when changing data plan or carrier
Use simultaneously	Can be used simultaneously with a physical SIM on supported devices	Depends on the number of SIM slots on the device
Suitable for	Travel, business trips, flexible plan-switching needs	Long-term use with a fixed plan

So, can an eSIM be removed?

No. An eSIM is not a physical SIM card, so it cannot be removed from the device in the usual way. An eSIM is built into the phone’s hardware and is managed entirely through settings.

In other words, with an eSIM, users do not remove it physically; they can only manage it through software.

What does “removing” an eSIM actually mean?

During use, many people refer to deleting or turning off an eSIM as “removing” the eSIM. However, this is only a colloquial way of saying it and is not technically correct.

Turn off eSIM: the eSIM is still on the device and can be turned back on when needed
Delete eSIM: the eSIM profile is removed from the device and usually cannot be installed again if the plan has already been activated

This difference is what leads many people to think an eSIM can be “removed” like a physical SIM, when in fact the nature of the two is completely different.

When do users need to delete or turn off an eSIM?

Deleting or turning off an eSIM should not be done casually, because these two actions have completely different purposes and consequences. In real use, users should only delete or turn off an eSIM in certain specific cases.

Cases where you should turn off the eSIM

Temporarily not using the eSIM but still want to keep it for later
Switching to another SIM for mobile data for a short period
Avoiding the eSIM connecting to a network before reaching the intended area of use

Cases where you should delete the eSIM

You have finished using the travel eSIM and no longer need it
You are preparing to switch to a new eSIM and do not need to keep the old one
You need to delete the eSIM following technical support instructions when installation issues occur

Important note:

With many travel eSIMs, deleting the eSIM means it cannot be reinstalled

Check whether the eSIM plan is still valid before deleting it

When abroad, only delete the eSIM if you already have an alternative connection method

How to manage eSIM on iPhone and Samsung

Unlike a physical SIM, an eSIM does not need to be inserted or removed and is managed entirely through software. On iPhone and Samsung, users can actively turn eSIMs on/off, switch between them, or delete them directly in settings, depending on their needs.

Managing eSIM on iPhone

On iPhone (from XR onward), the eSIM is managed in Settings > Cellular. Here, users can:

View all eSIMs installed on the device
Turn each eSIM on or off without affecting other eSIMs
Choose the eSIM used for mobile data while keeping the physical SIM for calls and SMS
Rename the eSIM (for example: Hong Kong eSIM, Travel eSIM) to make it easier to distinguish
Delete the eSIM when the plan expires or is no longer needed

iPhone allows multiple eSIMs to be stored on the same device, but the number of eSIMs that can be active at the same time depends on the device model.

Managing eSIM on Samsung

For Samsung Galaxy models that support eSIM, users manage eSIMs under Settings > Connections > SIM Manager. The main actions include:

Check which eSIM and physical SIM are active
Turn the eSIM on or off independently, without removing the main SIM
Choose the eSIM as the mobile data SIM when traveling abroad
Switch between eSIMs already installed on the device
Delete the eSIM when you want to change to a different plan

Samsung supports using an eSIM and a physical SIM at the same time, which is suitable for people who want to keep their personal number but still use an eSIM for travel or business trips.

When is an eSIM a suitable choice for travel?

In practice, an eSIM shows its greatest advantages on trips where users need fast, convenient, and flexible connectivity, but do not want to change their main SIM. An eSIM is a suitable choice if you fall into one of the following cases:

You want internet as soon as you arrive, without having to look for a SIM counter or rely on public Wi-Fi
You do not want to remove your physical SIM to avoid losing your number or interrupting important calls or messages
You only need mobile data for a short trip and do not need voice calls
You travel frequently or visit multiple destinations and need a flexible, easy-to-manage solution
You prioritize portability, self-service setup, and control over your connection directly on the device

Frequently asked questions related to “Can an eSIM be removed?”

Below are common questions users have when learning about deleting, managing, and securing an eSIM in real use.

If I delete the eSIM on my old phone, can I install it again on a new phone?

Most eSIMs, especially travel eSIMs, cannot be installed again on another device after activation. Each eSIM QR code is usually for one device and one installation only. When you delete the eSIM from your old phone, you will not be able to transfer that eSIM to a new phone, except for some special carrier eSIMs that support transfer according to their own policy.

I sold a phone after deleting the eSIM. Can the buyer use my number again?

No. Once the eSIM has been deleted from the device, all plan information and subscriber profile data are also removed. The buyer will not be able to use your eSIM number again or access your data, as long as you deleted the eSIM properly before handing over the device.

Can an eSIM be “hacked” or have information stolen if it cannot be removed?

No. The fact that an eSIM cannot be physically removed does not increase security risks. An eSIM is stored and managed within the device’s security system and is controlled by the operating system. When users lock the phone, sign out of their account, and delete the eSIM, the related data cannot be accessed from outside.

How can I check how many eSIMs are stored on my phone?

You can check directly in the device settings:

On iPhone: go to Settings > Cellular to view the list of installed eSIMs
On Samsung: go to Settings > Connections > SIM Manager

Here, you will see the eSIMs that are active or stored on the device and can manage each one separately.

What should I do if I accidentally delete the eSIM?

In most cases, a deleted eSIM cannot be restored, especially travel eSIMs. If you accidentally delete an eSIM while the plan is still valid, contact the provider immediately to check whether support is possible. However, to avoid risk, users should prioritize turning off the eSIM instead of deleting it when they are not sure.

Hopefully, after this article, you now clearly understand whether an eSIM can be removed, as well as how to manage, delete, or turn off an eSIM properly during use. Once you understand the nature of eSIMs, you will find it easier to choose and use this technology proactively, safely, and in a way that better suits your actual needs.
