FAQ
Find frequently asked questions here. If you still don’t find answers about our SIM card and internet, contact us.
Q1: Will SK SIM Card work reliably in rural parts of Japan and on the Shinkansen?
A: Yes. SK SIM card runs on Japan’s premium networks, providing extensive nationwide coverage. It remains exceptionally stable even while traveling on the Shinkansen (bullet trains) and exploring remote countryside villages or mountain shrines.
Q2: Do I need to manually configure APN settings on my phone for SK SIM?
A: For iPhones, the network configuration usually updates automatically upon insertion. For Android devices, a quick manual entry of the Access Point Name (APN) settings might be required. Step-by-step instructions are provided in our English setup guide.
Q3: Can I check my remaining data balance during my trip with SK SIM?
A: Yes, you can monitor your total data usage directly through your smartphone’s built-in data tracking settings menu under “Cellular Data” (iOS) or “Data Usage” (Android).
Q4: Can I get a local Japanese phone number for regular voice calls with SK SIM?
A: No, because local regulations in Japan dictate that phone numbers with voice/calling capabilities can only be purchased by residents holding a valid Japanese Residence ID. For tourists and business travelers, SK SIM provides high-speed data-only solutions that bypass this legal restriction completely, allowing you to get connected instantly without needing a residence ID.
Q5: What happens if my SK SIM package runs out of data or validity?
A: Once the prepaid duration or high-speed data tier is completed, the connection will either stop or be heavily throttled. We advise choosing a plan that aligns perfectly with your full itinerary or opting for our high-capacity tiers.
Q6: Can I keep my original WhatsApp or LINE account active while using SK SIM?
A: Absolutely. Switching to SK SIM for data routing will not affect your chat applications. Your WhatsApp, LINE, and WeChat accounts will remain tied to your original home phone number without losing any chats.
Q7: What type of SIM sizes are provided by SK SIM?
A: Our physical card ships as a 3-in-1 “Trio SIM.” It includes all standard sizes (Standard, Micro, and Nano). You simply punch out the exact size that fits your specific phone model’s SIM tray.
Q8: Why should I prefer local routing over a global roaming SIM card?
A: Global roaming brands often reroute your cellular data through servers abroad (e.g., Europe or Hong Kong), adding significant lag/latency. SK SIM uses 100% native Japanese network routing, keeping maps responsive and video calls fluid.
Q9: Does SK SIM support dual-SIM configurations?
A: Yes. You can keep your primary home SIM active for emergency texts/calls while setting SK SIM as the primary source for “Cellular Data” to prevent unexpected roaming fees from your home carrier.
Q10: What is the minimum activation timeframe for an SK SIM plan?
A: We offer highly flexible options ranging from short 4-day weekend getaway plans up to extended Multi-Week packages designed specifically for long-haul explorers or business travelers.
