What’s Included and What’s Not

When you pick up your SIM, you get the SIM card itself plus an instruction manual to guide you through activation. However, it does not include a SIM pin, voice calls, or texts. If you rely heavily on voice communication, you might need an additional plan or VoIP apps like WhatsApp or LINE.
Also, keep in mind that most travelers book about five days in advance, so plan ahead to ensure your SIM is ready when you land. Once booked and paid, changes aren’t usually possible, so double-check your details.

Your adventure begins at Kansai International Airport, specifically at the designated counter or pickup point.

However, it’s essential to remember that this SIM card is only for mobile phones—if you need a portable WiFi device, you’ll need a different solution. Some users noted that activation instructions are clear but recommended having a bit of patience, especially if it’s your first time setting up a Japanese SIM.
