Everything works great, the only thing is that you have to turn off the main SIM card for everything to work properly.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!

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!
