Excellent value and reliability. Purchased in Sydney, Australia and started installing the eSIM using the QR code. Installation fully completed only upon arrival in Bangkok when it can be connected to the local network. Installation will be not be completed before you arrived in Thailand - so no need to be alarmed when you get an "error" message prior saying installation cannot be completed.

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!
