I used the esim in Seoul and Incheon. A speed was fine
Ulsan, Busan and Seoul. Mobile network everywhere! Excellent!
Good description how to use the SIM!
It was easy to install and I had internet everywhere. I hoped just to read my maps etc but it was so much better than I thought. Sending text and photos wasn't a problem.
I liked the coverage in Jeju and Seoul but I was a little unhappy that I could not activate the e-sim pre-departure as it would count as a day's usage. I wasn't sure if the free wifi at Jeju airport would be good enough to activate the e-sim as well.
I used the esim for one week travel to Seoul and Busan. Coverage and speed is fine.
eSIM Korea Fixed Plans
Easy to set up eSIM as step by step instructions were given on the website and it worked throughout my trip in Korea.
Very easy to get and to install to the device, it only took a few minutes and it was good to go, I had unlimited data for every day of my trip. I would 100% repurchase whenever I go back
Works flawlessly. Replace an Airalo that was a nightmare with constant disconnecting, my next travels will be with e SIM World
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. TIP: you can see how much data you've used so far in settings.
I turned off my US SIM card and used airport wifi to activate my Korea eSIM. It worked great. At first, it took a bit to get going (not sure why or if there is a way to speed up the process), but once it got going, it was great. The service was generally fast, and it was much cheaper than my US carrier's international plan.
Perfect eSim! Works very good. Everywhere. No problems with the range. O am very satisfied with this eSim.
I had no problems at all. It was was efficient and worked very well.
