The most convenient HanaCell From applying to submitting supporting documents to actually getting the card, the entire process can be carried out online, which is very considerate. Easy to use and a good company with credit.

Easy to use but expensive Even though their yearly subscription fee is low, their activation fee is high. Additionally, both the cost of data and calls are also high. For my 10-day trip in Japan, I ended up spending around $100. I later learned there are many other similar services available, so I’ll do more through research next time.

Best sim for all citizens Probably the best SIM for Japanese and any citizens including US. This is likely the only SIM you can pick up at the airport, which you don’t need the address in Japan (which mean you can legally have Japanese number in Japan). Best thing? You only need to pay maintenance fee less than $10/year, and if you use the calls and text you pay the amount corresponding to it. Receiving text/call is free. 一時帰国や外国人にオススメです。このsimは恐らく唯一空港で受け取れる日本の電話番号付きsimです。つまり日本の住所が無くてもオッケー。毎年10ドル以下の維持費と使った分だけ払えば良いのですごく便利！

best to use for PIA and LAWSON It's easy to buy and receive. Compared to other competing services, it's easy to use a cell phone to make calls to get tickets. I highly recommend it to my friends!

So good! It was inconvenient that I didn't get a phone number after I came to USA , but it was very helpful that they responded immediately after I applied.
