Upon landing down at Narita Airport, I was able to collect the SIM card fast from the designated collection point. Though there wasn't much info given by Headout on the Sakura SIM card and that I actually had to look up the full details on the official Sakura SIM website, the SIM given to me was still legitimate and was the official SIM card. For some pointers, you can get unlimited fast data for up till 2GB a day before your data is slowed for the rest of the day. The 2GB resets every 2359 so it should be okay. For me, I used my SIM card to travel around and to keep in contact with people and I had a Mobal plan as a backup in case i really needed to call someone/message urgently. With the high allowance of the 2GB, I was able to actually watch my youtube videos while on the move while watching it in low quality of course. Theses videos would be 1 hour to 3 hours long so the Sakura SIM card was really useful for giving me the high allowance. Overall, i would purchase this service again should i need to go back to japan.
