12 days data SIM
The package was delivered to Narita airport post office. The pick up was pretty fast. They gave me two 6 days SIM cards for a total of 12 days. The installation was easy if you know how to out in a SIM card for your phone. The instructions were clear and in English. I had no problems with my SIM card for the entire trip. I used it to to WhatsApp calling and the voice was clear. Very good service I would recommend it to everyone =).
