Introducing the prepaid SIM “MightySIM” that is perfect for European tours!


After staying in Finland for 2 months, it became a reckless journey of moving 10 places in a month. The most troublesome is the SIM problem. If it takes just 4 hours by land movement, SIM is different depending on each country to go to the next country, and it is difficult because you have to go overseas roaming procedures. I usually travel without a SIM, but because there are many hurrys, I need a quick Wi-Fi, so I bought this SIM when I was in Japan to prevent irritation.

In some countries it is cheaper to use the local SIM. It’s still a good price if you’re up to Europe, but it suddenly increases when you enter Plan 2. Also, basically, the portion that is not used within 30 days after purchase becomes invalid, so it will be used up.

1$ = roughly 107-110 yen.
