I purchased the eSIM from Ohayu via online in South Korea but I couldn’t use it immediately. By the way I’m from San Francisco. So I contacted the support. Make it short, it was not the eSIM but my phone setting had some issues! Ella helped me with clear step by step instructions. I am not good at any of those setting and don’t know anything so I took time to follow the steps. But she was very patient and very knowledgeable! She waited for me for each step and we finally made it work! Took a great amount of time because I was slow. Started feeling a bit discouraged but she was polite and very responsive. Thank you Ella! Thanks to her, now I can enjoy BTS world tour!!! Ella, you made this trip more special!!! Thank you!!!
Outstanding support team never quits! Now I can roam at will!

I was having major problems activating my new eSIM. Anthony and the rest of the support team, Ophelia, Elliot, Constance and Anna took some 2 days, 33 emails and many screenshots before it got straightened out and was determined to be the local carrier not applying the correct settings automatically. Fortunately, the teams, persistence and patience helped me keep trying, and I now have a fully functioning eSIM to use as I travel for the next three weeks in Vietnam and Cambodia. And just one day it has already proven crucial to be able to navigate and translate as I moved through my day.

I was having issues activating the eSIM and was frustrated that I was only getting the automated response. Then a human responded to my email and asked for screen shots of my phone settings. They fixed it quick🙏 thanks Elliot.
