Frequently asked questions
How much does the Japan eSIM cost?
The Japan 5GB 30Days (IIJ) plan costs $4.32 for 5 GB over 30 days, paid once with no hidden fees.
How do I activate my Japan eSIM?
Scan the QR code in your phone settings (Cellular/Mobile → Add eSIM) or tap Install in the eSIM TopUp app. Install on Wi-Fi before your trip; it activates when you arrive in Japan.

It works on any eSIM-compatible, carrier-unlocked phone — iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy models.
Can I keep my regular number?
Yes. The eSIM runs alongside your normal SIM, so you keep your number for calls and texts while using data in Japan.

Does this work on an iPhone 13?
Hi Liam, yes — the iPhone 13 supports eSIM, so the Japan plan will work as long as your phone is unlocked. You just scan the QR code under Settings › Cellular › Add eSIM. Any questions, reach us at esimtopup.io/support. – Ingrid

Do I need to install it before I travel or after I arrive?
Set it up before departure. Installing needs internet, and airport Wi-Fi is not always reliable.

Is roaming charged extra or is it all included?
No extra roaming fees — the price you see is the price you pay.

Can I top up the same eSIM instead of buying a new one?
Top-ups are supported on most plans — look for "Top-up supported" on the plan page.

Does the validity start on purchase or on first use?
Validity starts on first connection at your destination, not at purchase.
Aisha R. · 5 months ago

Is 5G supported or just 4G?
Yes, 5G where available. Coverage depends on the local operator in that country.
Diego V. · 6 months ago
Can I use it in nearby countries too?
That depends on the plan — country plans work in that country only, while our regional and global plans cover multiple destinations.
