Easy set-up

It was easy to buy and easy to install. I'm a tech guy, so I know what to do, but I believe anyone can do it. Very easy to use this and the speed/reachability of the network was more than sufficient. I can only recommend this.
Rose Verified Buyer

It saved time and money

It was my first experience with an eSIM and I loved it. Provides me instant eSIM. Didn’t have to queue at the airport to arrange connection as it was all done online. I will definitely use it next time as well.
Haul Verified Buyer

Clear instructions

The information from the service provided was clear and I was able to set up the eSIM easily. My son’s iPhone 12 performed better with eSIM Korea than my iPhone 10XR, but in general I was pleased with the service.
Kin Verified Buyer

Best eSIM provider

In the beginning, I thought I received a faulty eSIM, but it is because I didn't read the instructions well enough, and didn't turn on data roaming. After that, it worked perfectly. Support team replied to my queries very fast.
John Verified Buyer

Reliable & Fast service

Daegu, Busan and Seoul. Mobile network everywhere! Good description how to use the eSIM. Very reliable and quality service.
Emily Verified Buyer

Excellent connection

The eSIM activation code was available within less than an hour after payment and set up was very fast. Only slightly lagging at some places but overall very good connections
William Verified Buyer

Good service

Cheap and does what it needs to do. I wasn’t able to call with my phone, but email and most apps worked. Used for Uber, google maps, instagram, tripadvisor with the family.
Shone Verified Buyer

Best choice!

It is a life saver. The service was generally fast, and it was much cheaper than my US carrier's international plan. however, I can’t track the data usage. Would be great to have an app.
Marvin Verified Buyer

Happy overall

It was just perfect. It worked as expected, all the time I had good signal and no limits for the speed of the internet! My vacation without problem. In Seul and Jeju.

    There are more infrequent questions
    What is an eSIM?

    SIM stands for “Embedded Subscriber Identification Module”, and is a revolutionary technology that enables the activation of a cellular plan without using a physical SIM card.
    The eSIM works the same way as a traditional SIM card, providing the necessary identification and connectivity features for mobile devices.

    The distinctive aspect of eSIM is that it comes pre-installed in the devices. Users can simply activate the eSIM by scanning a provided QR code, bypassing the wait for SIM card delivery and eliminating the need for physically swapping SIM cards. This innovation offers enhanced convenience and flexibility in managing cellular plans for modern mobile users.

    When should I buy my eSIM?

    You can make a purchase anytime at your convenience. You may purchase an eSIM plan the day prior to your travel date or upon arrival at your destination.

    To activate the eSIM plan, your device must be connected to a cellular data network or Wi-Fi. We recommend that you activate an eSIM plan by using a public Wi-Fi network like those available at an airport or hotel.

    Can I pay with cash or different payments besides PayPal?
    We currently accept payment only through PayPal. However, please note that you don’t need to have a PayPal account to make the payment. You can use your credit or debit card to make the payment without creating a PayPal account.
    How can I install the eSIM on my device?

    There are 2 ways to add an eSIM to your device (please note that these steps may differ depending on your device & language.)
    To activate the plan, you need to be connected to a strong WiFi signal and not in airplane mode.

    A. Activate by scanning the QR code 
    iOS:
    1. Go to [Settings] - Tap [Cellular/Mobile Data]
    2. Tap Add [Cellular Plan] or [Mobile Data Plan]
    3. Scan the QR Code that you received via email.
    4. Your device will automatically start activation instructions.
    Android:
    1. Go to [Settings] – [SIM Card Manager] – [Add a Mobile Plan]
    2. Go to [Scan Carrier QR code]
    3. Scan the QR Code that you received via email.
    4. Your device will automatically start activation instructions.

    B. Activate by typing manual information.
    iOS:
    1. Go to [Settings] – [Cellular/Mobile Data] – [Add Cellular Plan] – [Enter Details Manually]
    2. Enter [SM-DP+ Address] and [Activation Code] which you’ve received through email with a QR code. (Please make sure you don't paste with https:// or http://)
    3. Your device will automatically start activation instructions.
    Android:
    1. Go to [Settings] – [Connections] – [SIM Card Manager] – [Add a Mobile Plan]
    2. Go to [Scan Carrier QR code] – Tap [Enter activation code] instead
    3. Type [Activation Code] which you’ve received through email with QR code. (Please make sure you don't paste with https:// or http://)
    4. Tap [Connect] – [Add and use it now] 5. Your eSIM plan will be activated automatically as you set the details.

    Can I install my eSIM on multiple devices?
    No. You can’t scan the same QR code on multiple devices. In addition, one QR code can’t be scanned multiple times. The scan will not work if the number of scans exceeds the limits.
    How do I check if my phone is unlocked?
    You can’t use an eSIM with a locked phone. To check whether your device is locked, please contact your carrier or check the [Settings] menu and find either [Add eSIM] or [Add Mobile Plan]. If your phone is locked, you should contact your domestic carrier to unlock your phone before you can use the eSIM plan.
    How can I know which eSIM plan I am using for cellular data?

    On iPhone, go to [Settings] - [Cellular/Mobile Data] and check ‘Cellular Data’ to see the plan selected.
    On Android, go to [Settings] – [Connections] – [Mobile data] and check which plan is selected.

    Your device will specify whether it is using data from the Primary SIM or the eSIM.
    If you have installed multiple eSIM plans, your device will also specify which eSIM plan is being used at the moment by displaying the label you chose for your eSIM plan at the point of installation.

    How can I check the balance or remaining data?
    For now, you will not be able to view your data usage on our website. We will add this feature as soon as possible for your convenience. To check the accurate remaining data, please contact us via [email protected]. We’ll check and let you know. To briefly check, if you are using an Apple iPhone, you can go to [Settings] – [Cellular] – [Usage] and check how much cellular data you have used. For Google Pixel, go to [Settings] – [Network & Internet] – [Data usage] and check how much cellular data you have used.
    Can I receive phone calls on my home country’s number?

    Yes, but the feature varies depending on your device. The Dual SIM Dual Standby(DSDS) technology in compatible device models lets you remain connected with your physical SIM and your eSIM simultaneously.

    Please note that using your home country’s number will incur additional fees charged by your domestic carrier. (Please be advised that the Google Pixel 3 series is not compatible with DSDS technology.)

    Can I delete and reinstall my eSIM plan?
    Once an eSIM plan is installed, it can’t be reinstalled or reissued. If you are facing any problems, please don’t delete your eSIM plan - instead, contact Team WHIZ via [email protected] first.
