A very convenient service, I'm using it for the second time. The connection is everywhere, and I haven't had any problems. Installation is very simple.

It's very convenient. I ran out of data on my SIM card and all the offices were closed, so I used it. Everything was very fast and efficient. And the connection is superb.

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.

I've been traveling for three months: Vietnam, Cambodia, Indonesia, Thailand, and Malaysia. I've never had any internet issues. The connection is stable, the speed is good, and the 10 GB of data is enough for maps, messaging, and ordering a taxi. I recommend it. I've been using Trip offers for years. The key is to read the description carefully, with the option to extend the package.

An excellent eSIM for Vietnam. It activated without any problems upon arrival, the internet speed is high, and I had excellent coverage everywhere. It's very convenient that it's a local IP address—I had no issues with maps or services. The price is quite reasonable for such convenience. I'll be using it again.
