Frequently asked questions – eSIM for Japan
Does an eSIM for Japan work as soon as I land?
In most cases, yes. After you install the eSIM and enable data, it will connect to a local network in Japan when you arrive. Some plans activate on first use in the country.
Can I use the eSIM in Japan for calls?
Our plans are data-only. For calls you can use VoIP apps (WhatsApp, FaceTime, etc.) over the eSIM data, or use your primary SIM for voice if your operator allows.
What if I run out of data in Japan?
When the included data is used up, the eSIM stops providing data unless your plan includes a top-up option. Choose a plan with enough data for your stay or consider a larger bundle.
Is the eSIM valid only in Japan?
It depends on the plan. Single-country eSIMs are valid only in Japan. Some plans also include roaming in neighbouring countries – check the plan details.
When does the validity period start in Japan?
Validity usually starts when you first use data in Japan (or when the plan is activated, depending on the product). Check the terms in your confirmation email.
Can I use hotspot with my eSIM in Japan?
Yes. If your device allows it, you can share the eSIM connection via hotspot. Data used by other devices counts against your plan allowance.
Do I need to remove my home SIM to use the eSIM in Japan?
No. You can keep your home SIM and use the eSIM for data only. Set "Mobile data" to the eSIM line in your device settings.
Will my phone work in Japan with this eSIM?
Your phone must support eSIM and the frequencies used by local networks in Japan. Most recent iPhones and many Android models are compatible. Check our device compatibility page.
How do I switch back to my home SIM after leaving Japan?
In Settings, set "Mobile data" back to your primary SIM. You can leave the eSIM installed but inactive, or remove it when the plan has expired.
Is it safe to buy an eSIM for Japan online?
Yes, if you buy from a trusted seller. Simcardo uses secure payment and delivers the eSIM by email. Keep your confirmation and QR code in a safe place.
Are there any special restrictions for using eSIM in Japan?
Use of eSIM in Japan follows the same general rules as elsewhere. Ensure your device is compatible and that you use the eSIM in line with local regulations.
What are the best areas for coverage in Japan?
Coverage in Japan is typically best in cities and main tourist areas. Remote or mountainous regions may have weaker signal. Check coverage information for your route.
Can I top up my eSIM while in Japan?
