The main thing is to enable data roaming. Otherwise, the SIM card works without any problems. A huge thank you to the operator for providing communication services.

I traveled solo as a woman from Vietnam to Cambodia by land, staying in Cambodia for 9 nights (2 nights in Phnom Penh, 1 night in Kratie, and 6 nights in Siem Reap) ♪ This eSIM made my trip a fulfilling one ^ ^ I'll use it again!

We bought an e-SIM and couldn't activate it at first, and we were upset we'd wasted our money. But after contacting customer support, we realized the card could only be activated once we were in Thailand, and we'd tried to do it before our flight. Thanks to customer support for their help!

I used it on my trip to Chiang Mai. I had no trouble getting around the city. I also ventured into the mountainous areas, where the signal was poor, making internet searches and social media slow. However, the map was not a problem.
