I connected without any problems while I was right there in Thailand. This was my first time connecting an eSIM. Now I only use this method to select and connect a SIM card when connecting. 👍👍👍

Excellent connection, quick installation, and we connected via Wi-Fi while we were already on-site. For convenience, it's best to activate it at home the day before your trip.

Easy to set up, stable signal, good price. I highly recommend an e-SIM for all travelers. We bought my husband a SIM card on site (his phone doesn't support e-SIM) for four times the price.
