I got two eSIM cards, activated one from the airport, and shared the other using tethering. For daily use, I got the 2 GB/day plan, which was more than enough. Everything works flawlessly.

Excellent connection quality, and the SIM card was a big help in Malaysia. It was quick and easy to connect, overall, I recommend it.

I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.
