FAQ
Find frequently asked questions here. If you still don’t find answers about our SIM card, please contact us.
Q1: What is the main advantage of using SIM card by SIM Point over buying a SIM card at Japanese airports?
A: Buying at the airport often means waiting in long lines and paying inflated tourist prices. SIM Point allows you to secure your high-speed connection ahead of time, ensuring instant setup and 100% local routing without the premium airport retail markup.
Q2: Does the SIM Point SIM card package include a local Japanese phone number for voice calls?
A: Under Japanese law, voice-call SIM cards require a local Residence ID (Zairyu Card) and are not legally available to short-term tourists. Therefore, SIM Point offers strictly high-speed data-only plans (4G/5G) which do not require any residence ID. You can still make unlimited voice and video calls seamlessly using data-based apps like WhatsApp, FaceTime, or LINE.
Q3: How do I know if my smartphone is compatible with SIM Point eSIM?
A: Your phone must be carrier-unlocked and support eSIM technology. Generally, iPhone XR or newer, Google Pixel 3 or newer, and flagship Samsung Galaxy devices support eSIM. You can check your lock status in your phone settings under “Carrier Lock” or “Network.”
Q4: Is there a Fair Usage Policy (FUP) on the unlimited data plans?
A: To maintain network stability for all users, a standard Fair Usage Policy applies depending on your chosen package. If you exceed the high-speed daily threshold, your data stays connected but speeds will be throttled until it completely resets at midnight (JST).
Q5: When should I install and activate my SIM Point eSIM?
A: We highly recommend installing the eSIM profile via the provided QR code while you are still at home or have a stable Wi-Fi connection just before departure. The data plan billing cycle will only begin once your device registers on a Japanese cellular network.
Q6: What mobile networks does SIM Point utilize in Japan?
A: SIM Point connects directly to Japan’s premier, top-tier networks (such as NTT Docomo or au). This guarantees broad nationwide coverage, high-speed data delivery, and zero roaming lag from Hokkaido down to Okinawa.
Q7: Can I use personal hotspot and tethering with my SIM Point card?
A: Yes, mobile hotspot and tethering are fully supported on both our physical SIM cards and eSIM profiles, allowing you to easily share your high-speed internet connection with tablets or laptops.
Q8: What should I do if my iPhone shows "No Signal" after inserting the physical SIM card?
A: First, ensure your device is fully carrier-unlocked. If it is, check if you have any old configuration profiles from your home carrier or past travels installed by going to Settings > General > VPN & Device Management, and remove them.
Q9: Do I need to return the SIM card after my trip to Japan ends?
A: No return is necessary. Our travel SIM cards are completely prepaid and disposable. Once your validity period expires, you can simply remove and discard the physical chip or delete the eSIM profile.
Q10: Can I buy a SIM Point data plan if I am already inside Japan?
A: Absolutely. If you choose our digital eSIM option, you can purchase it anytime while in Japan. The QR code activation token will be delivered to your email inbox within minutes, allowing immediate connectivity.
