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.★

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.★

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.★

Guest User2025-10-30
I purchased an 8-day eSIM, and it was stable throughout my trip to Fukuoka, including visits to Ito-majima and Dazaifu. It automatically switched to 5G when there was a 5G signal and 4G when there wasn't. The only time I encountered a very weak signal was in a basement restroom in a shopping mall; it was fine once I left, which was due to the mall's antenna coverage and not related to the eSIM. I installed the eSIM in China the day before departure. During installation, it might show an activation failure message, but that's normal. Wait until you can access the eSIM card and then turn it off. Once in Japan, activate it again and switch your cellular data to eSIM. It uses a local IP address, so you don't need to enable data roaming. You can also create a hotspot. The whole experience was smooth, and the price was reasonable. Highly recommended!★

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!
