Will buy again, great, no network disconnection problem

1GB per day is basically not for watching videos or uploading photos, but just texting and looking at maps. In addition, there are many WIFIs available in Korea, which is actually quite sufficient, and the network stability is very smooth.

This time I used it in Busan. It was really smooth and the Internet was not disconnected. The Internet signal was also very good when I was on the yacht~

Credit cards are accepted for payment.

Why do prices show USD or NT$ when I switch language?

On this store, display currency follows the language you choose:

Checkout settlement stays in the store currency (USD). Cards and payment gateways charge USD. When the display currency differs from USD, cart and checkout show a short note with the charged amount and an approximate display equivalent.

Switching language does not clear your cart; it only changes UI language and display currency.

Quick tips before you travel

If you are short on time before departure:

Physical SIM (Taoyuan Airport pickup)

Best if you need a physical SIM and can collect at Taoyuan Airport on departure day. Order online first, then collect with your order number.

eSIM (QR code by email)

Best if your phone supports eSIM. After ordering, the eSIM is sent to your email.

Physical SIM sizes

We provide a 3-in-1 SIM (Nano / Micro / Standard) plus an ejector tool. Punch out the size that fits your tray.

Compatible devices

Our SIMs work on most unlocked 4G phones. Some older devices or region-specific models may differ due to band or OS compatibility. Not supported

Tablets
Translators
Wi-Fi hotspots / pocket Wi-Fi
Carrier-locked phones
3G-only phones
Modified / jailbroken devices
Some carrier house-brand models
Certain China / HK / Macau region models
US / Japan carrier-locked phones

How to use a physical SIM

Insert the SIM only after you arrive at the destination. Do not insert it before departure. On dual-SIM phones, put our SIM in Slot 1. Leave Slot 2 empty if you do not need Taiwan SMS, to avoid interference. Then enable mobile data and data roaming:

iOS: Settings → Cellular → Cellular Data on → Data Roaming on
Android: Settings → Network & internet → SIMs → Mobile data on → Data roaming on
Xiaomi / Redmi: Settings → Network & internet → Advanced → International roaming → allow apps to use data

Can I insert the SIM in Taiwan before departure?

Do not insert the travel SIM before you reach the destination. Inserting it early can register the wrong region and cause failures.

How are usage days calculated?

The validity period is calculated based on the local time at your destination. The activation date is counted as Day 1. For example, if the SIM card is activated at 9:00 AM, Day 1 ends at 11:59 PM on the same day.

Does it support hotspot sharing?

All of our products support hotspot sharing. For the best network speed and connection stability, we recommend sharing your connection with one device at a time.

The shared device may experience slightly lower signal strength, network speed, and connection stability than the primary device. Using multiple devices simultaneously may also affect overall network performance. For the best experience, we recommend using one eSIM per device.

Can I receive Taiwan SMS abroad?

Receiving Taiwan SMS abroad depends on the plan and local carrier rules. Many data-only plans do not include Taiwan SMS delivery overseas. Check the product notes or ask support for your plan.

Why is the network slower in some areas?

Network speeds may vary depending on your location such as airports, underground locations, mountainous areas, offshore areas, or remote locations due to limited network coverage or signal obstruction. The receiving capabilities of different devices may also affect the actual network experience.

Moving to an open area or a location with stronger signal may help improve the connection. If the issue persists, please contact our customer support team for assistance.

VPN and device management notes

VPNs or configuration profiles on iOS may affect your network settings, which can result in slow speeds, connection issues, eSIM installation failures, or an unstable connection. For the best experience, we recommend temporarily disabling any VPN during use and checking that no configuration profiles are installed on your device.

iOS Settings: Settings → General → VPN & Device Management

Why does my phone show no number?

Most plans are data-only and do not include voice calls or SMS services. “No Number” may be displayed after installing the eSIM or inserting the physical SIM card.

This does not affect your data connection. Make sure Mobile Data and Data Roaming are turned on for network access.

This time I used it in Busan. It was really smooth and the Internet was not disconnected. The Internet signal was also very good when I was on the yacht~

The connection quality is very good, and the setting operation is very simple. If you have any questions, you can directly ask the customer service online and they can get a timely reply. Like it.

When working abroad, I need to reply to messages immediately. There is no problem using this one. There will be no lag when I use it to start a live broadcast.

It was my first time to handle the Internet on my own when I went abroad. I was a little nervous at first, but it was actually easier than I thought.

The speed is very stable and the network is very fast. Although occasionally it will suddenly become slow when entering the room, it does not affect the overall usage.

When I went to Busan, I was originally worried about poor signal at the beach, but the result was super satisfying! Haeundae is very smooth for viewing the sea and looking up maps.

I went to South Korea during my annual vacation and it was so cold that I needed to navigate to a jjimjilbang or hot soup place. Fortunately, the network was very stable, otherwise I wouldn’t have been able to hold on~

I went to Seoul Tower on this trip and thought the internet would be poor in the mountains. But it turned out to be surprisingly smooth and I could share it immediately.

Going to a star chasing club in Korea for the first time requires a lot of internet usage. I saw that this Hallyu Card was highly recommended on the Internet, so I decided to buy it and try it out. Although the signal will be poor when there are many people in the venue, the Internet speed will be slower. But as a star chasing star, I also know that there will be such problems in venues in Taiwan, so I can accept it. As soon as I go out, the internet speed will be up instantly and it will be smooth in other places without lag.

I went to Korea for seven days before and the internet was no problem at all. It was very convenient. I repurchased it again and will fly again in August.

The shipping speed is very fast. You can use it immediately after you put it on in Korea. There are no dead spots in receiving signals. It is smoother than using it in Taiwan~

I received it the next day after placing the order, which is so fast!! The user experience is also very good, and watching YouTube on the subway is also very smooth!

The signal reception is very good. Basically, it can be used immediately after arriving at the airport. There are no problems with reception or signal interruption at any scenic spots. It is very good.

I received the card the next day after placing the order, shipping was very fast! The reception is pretty good and the internet speed is normal. There is no problem of being unable to access the Internet.

I have always used their Korea Tong in the past. This is the first time I have used the Korean Wave card. It is also very easy to use. It has fast network speed, is not expensive, and is an economical and affordable Internet card.

This time I traveled to Jeju Island and the Internet was very smooth. Although I seemed to be unable to connect to the Internet at first, the customer service staff helped me connect it smoothly.

Plug and play, no need to reboot or download other software. The network speed is very fast and there are no slowdowns or poor signal problems. Highly recommended!

This trip to South Korea happened to be hit by heavy rain, so the flight was delayed by one day. I asked customer service if I could increase the number of days, but luckily I could! Otherwise, it would be really troublesome to be stuck in Korea without internet for a while. Thank you again.

Cards can be shared. When traveling on a business trip, it is very smooth to use the mobile phone, laptop and iPad together. The reception is good and the speed is also very fast.

The Internet was very smooth for seven days in Korea. There were no major problems. If I encountered any problems, the customer service responded quickly and wouldn’t keep me waiting for too long.

The sim card is very convenient. There is no need for a Wifi sharing device, no need to charge it, no need to return it. It can be used by one person very smoothly and very conveniently.

The internet speed is pretty good and it’s very convenient. You can use it as soon as you plug it in. The editor also responded very quickly. I will buy it again next time.

It is a very fast network card. It is very good for receiving signals when traveling to Okayama, Tottori, and Sakaiminato. There are no network slowdowns or interruptions. I will buy it next time I go on a business trip.

It will be delivered directly to your home before departure. You can use it by changing the card in South Korea. The signal is also very good, even in the suburbs!! Highly recommended

The internet speed is very fast and stable, but it didn't work at first. I spent a lot of time at the airport and missed my scheduled bus. It took me a lot of time and money to get to the hotel.

I ordered online before going abroad and received the network card immediately. The Internet is also very fast and convenient. The number of days can be customized, which is convenient and affordable.

It was my first time to use this company's SIM card. I was worried that I would encounter the same problem as other companies, which would slow down or fail to upload pictures when uploading. The same problem is that the speed does not slow down when I am full. This one is very smooth to use, and I don't have to worry about driving it all day long. Moreover, it feels like great value for money when I buy it at a special price. Highly recommend

You can use it just by plugging in the SIM card. The network speed is very fast. I bought this one because I want to have a video conference. Every meeting is smooth and without delay. It is better than other network cards.

The reception in Seoul is good. Sometimes it says 4G and sometimes it says LTE, but they all mean 4G. I don’t know what the difference is. The speed is very fast.

It didn't work at first. I asked customer service and found out that I need to enable data roaming, but the speed was very fast and the roaming card was not connected.
