Internet speed is very fast and convenient

We found the esim handy when cycling and didn't have access to free wifi. We didn't need to make phone calls while in Sth Korea so just having access to wifi was perfect.

Fuss free eSIM setup, stable data connection for the 6 days I was in Seoul, cheaper than activating data passport from M1 yet with a local number for restaurant reservation.

This is my number one choice whenever I visit Korea. The customer service is so great and the product is wonderful. I really recommend this product and this company if you need to have a phone and data service when you visit Korea!!!

It's so convenient to scan the QR code I received by e-mail without the hassle of taking out and inserting the sim card 

I also love that I don't have to remove my existing sim card!

J**** 2023-03-28 69 5points

I bought it as a gift for a friend from abroad and it's so nice! 

It's convenient because can use the Internet by receiving the QR code directly through email. 

The internet is fast, too! It also has a number, so it was good to use when entering the country

It would have been better if it was aired. I'll buy it again next time!!

n**** 2023-03-28 71 5points

Good. Highly satisfied.

It was very convenient because I could download the plan by scanning a QR code. The data speed was fast enough. I recommended this eSIM to my friend also she satisfied with it. I will choose eSIM again for my overseas travels. Do not forget to do a registration on LGU+ website to activate the eSIM after the download !! I was a bit confused first time but it was quite simple.

The service quality of Korea SIM is great!! Even I'm a Korean, I haven't been familiar to use this kind of service. There were some issues, but they're trying to solve my problems as soon as possible. I was amazing that it was not their business hour. Later the issue was caused by my real sim. When you go to Korea, you should buy and use this SIM. Then your trip will be no problem at Mobile Internet Service!!

Very easy to purchase, very clear instructions as well. I was slightly impatient at first, because I recieved 1 email and no QR code. I reached out to the customer service on messenger, and they replied within 10 minutes, during which time the 2nd email arrived. This email had QR code and was working within 5 mins. Very fast 4g as well. Happy days
