Easy to install eSIM instructions. If I stuck then I can just chat with the trip.com and AI generated answer that helped me right at the spot.im glad I booked with trip.com

Works decently. On Android I need to photograph the QR code for installation with battery saver off. Installation takes approximately 30 seconds. Works in many Europe countries as advertised.

Wasn't able to connect in China. Not sure what the reason was. Also it requires connecting to activate in the desired country.

I bought this for my wife, who's phone didn't have the Trip app on it. By following the steps given I was still able to get this e-SIM to work. It was great and we never had any problems in China, Vietnam and Cambodia.

The connection is fast and easy. I bought it for the verification number. SMS messages are coming through, everything is great. It's a shame you can't extend it. I'll buy more.
