Frequently Asked Questions (SIM Cards)

Q. Do I need to return the SIM card before leaving Japan?
A. No, return is not required. You can simply remove the SIM card and throw it away once your plan expires or when you leave the country.

Q. Can I make phone calls with this SIM card?
A. No, this is a data-only SIM card. You will not receive a local Japanese phone number for standard voice calls or SMS. However, you can still use internet-based calling apps like WhatsApp, FaceTime, Skype, and LINE without any issues.

Q. How do I activate the SIM card?
A. Insert the SIM card into your unlocked phone after arriving in Japan. Most modern smartphones will configure automatically. If it doesn't connect right away, you may need to manually set up the APN (Access Point Name). Instructions are provided when you pick up your SIM.

Q. Can I use tethering (personal hotspot) with this SIM?
A. Yes, tethering is generally supported, allowing you to share your data connection with another device. However, if you plan to share data extensively, renting a Pocket WiFi might be more cost-effective and battery-friendly.
