CUSTOMER'S VOICE

Service used in Hokkaido, Japan

The 5G high-speed internet with unlimited data use is super convenient!

I've used SIM2Fly countless times during my trips to Japan. When I use SIM2Fly, the internet sometimes becomes sluggish and struggles to pick up signals in certain places while I'm on the move, especially when I'm binge-watching videos on my phone. But guess what? This SIM card really changed the game! Now, I can stream videos seamlessly throughout my entire trip, just like what I do back home in Thailand.

Service used in Tokyo, Japan

Easy to set up! Comfortable with just one smartphone!

Up until now, I had been using rental mobile WiFi. But since rental WiFi doesn't have long battery life, I also had to bring a mobile battery, which meant I had to carry quite a lot of luggage. [NihonSIM | JAPAN SIM Unlimited Data] can be used just by inserting the SIM card, so it was convenient to be able to walk around Tokyo with only one smartphone.
