This e-sim worked properly and i really enjoyed using it. At first, but, when you inatall the e-sim, it does not work right away because i had to wait for 5~10mins to make e-sim activated then it worked well.

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.
