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.★

Used in South Korea, *********. It connected instantly and worked smoothly in every country (region). I'm very satisfied, including the price. Since it supports multiple countries, it's convenient for transit, but because Japan is also included, you need to be careful about the number of days you purchase it for when activating it before departure. I bought a longer period, so I was able to use it in Japan after returning home.★

If you are visiting China and do not already have a Chinese mobile phone number, then you must have a eSIM card to move around, because China is a massive digital land!★

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.★

Excellent SIM card! I installed it on my phone ahead of time, and upon arrival, it immediately found a network and connected. It worked without any interruptions or speed drops the entire time.
