I just returned from Zhangjiajie and Fenghuang Ancient Town, and the eSIM was stable throughout the trip.

Mua Travel eSIM China ở đây rất an tâm. Nhận mã QR qua email, quét cài đặt trước ở nhà rất nhanh

My biggest worry in China was not being able to access Facebook or Google to contact home, but this eSIM connected smoothly without installing any extra VPN app.

Data thoải mái giúp mình check Google Maps tìm đường và đặt xe. Rất nên mua dùng

The plan is much cheaper than buying directly at the airport in Thailand.

I used this eSIM all around Bangkok, from malls to a boat ride on the Chao Phraya River, then down to Pattaya, and the signal stayed strong.

The first time I brought a foreign friend to Vietnam, I chose eSIM for convenience. It stayed stable throughout the trip, and my friend even praised it.

The network was generally stable, comfortable for Google Maps and social media. A few spots were a bit weak, but nothing significant.
