1. Why should I buy a 4G SIM card to travel to Japan?

1.1 Expensive international roaming costs

Currently, mobile phone service providers have implemented roaming services in Japan, but international roaming fees are very high, it will be very inconvenient and you will have to pay high fees if you have a long phone call or a lot of data is needed to use a navigation or translate app, so this may not be the most economical way to use your mobile phone in Japan. Check with your carrier before your trip to see how they charge for data usage, calling, and texting.

1.2 Free wifi hotspots in Japan have limited coverage, unstable quality

In order to improve the quality of the tourism industry, Japan has more and more free Wi-Fi hotspots in major cities as well as public places such as airports, train stations and convenience stores. However, in public places and cafes, even though there is Wifi, the access is very confusing, it is not easy to enter because it is denied or the hotspots force you to log in before using, or limit the access time access. Of course, if you are persistent and not too necessary, we still have free Wifi for a while, but is it really too time consuming?

Free Wi-Fi hotspots are a nice and welcome initiative, but their coverage is limited and you also need to consider the security risks if you really need internet access in these places.
