Great decision to use eSIM, especially in Vietnam. There is a good WiFi in airport Hoshimin so it was easy to activate. Good eSIM, everywhere worked. No need to go to the office. Just 1 minute and you are online.

I had problems with my auto roaming when I was travelling in China. Contacted my service provider multiple times and couldn't resolve my issues. In the end, my cousin recommended me to use this and the experience was great. I will be recommending this to my friends too!
