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.

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.

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.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!

My first eSIM! It was so convenient!!! I used it when traveling to Saudi Arabia. There was Wi-Fi at the airport and hotels, but I think you need to be prepared when traveling around town. Pocket Wi-Fi would be a bit of a hassle to carry, and I wasn't sure if I could buy a SIM card locally, so I bought an eSIM. I previously purchased an eSIM from another place, but I had trouble using it. This time, the instructions were detailed, the installation was easy, and after a little setup once I arrived, I was able to use it without any problems! It was so convenient that I'll definitely buy from here again!

Easy registration, activation instructions, and excellent technical support. I purchased a 1GB plan for 20 days, which is more than enough for messaging, maps, and data tethering. I used the network in Beijing, Malaysia, and Thailand, and everything worked reliably everywhere.
