Data worked well throughout my trip, even in the rural areas. There were occasions where the signal was cut/reset but largely ok! In the city, the speed was fast enough to send videos quickly, quite pleased! Also good that the data can be renewed

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!

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 used this when I went to Vietnam. I had a layover in Hong Kong on my way to Vietnam, and then went to Shenzhen (China). I bought this SIM because it covers three regions. Once I entered each region, I was able to receive a signal normally, so I was able to use it without any problems. However, I was surprised that LTE or 3G lines were the mainstay (in Shenzhen, 5G was available for a brief moment, but it quickly switched back to LTE). I did think it would be nice if it had at least 4G. It's cheap, so it's okay.

I always use it when I come back to Japan during my trip around the world. It's easy to connect to the internet, so I can use mobile payments like Mobile Suica and Rakuten Pay.
