Frequently asked questions
How much does the Japan eSIM cost?
The Japan 10GB/Day plan costs $8.00 for 10 GB/day over 1 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.
Will this eSIM work on my phone?
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.
Comments & questions
Carlos B. · 1 week ago
Do I need to install it before I travel or after I arrive?
Hi Carlos, you can install it before you fly — the QR scan only takes a minute, and the plan won't start until it first connects in Japan. That way you're online the moment you land. — Grace

Does this work on an iPhone 13?
It does. Every iPhone from the XS onwards supports eSIM, including the 13.
Wei V. · 5 months ago
Which networks does this connect to?
It uses local partner networks and picks the strongest signal automatically — the operators are listed on the plan page.
Haruto D. · 5 months ago
Can I use this for hotspot/tethering?
Yes, hotspot and tethering are supported. It uses your plan data as normal.
Diego B. · 5 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.

Glad it went smoothly. Enjoy the trip!

Does the validity start on purchase or on first use?
First use. Buying in advance does not eat into your days.
Anna P. · 11 months ago
Is 5G supported or just 4G?
Yes, 5G where available. Coverage depends on the local operator in that country.
Liam F. · 1 year ago
Will this keep my WhatsApp active with my home number?
Yes. The eSIM handles data while your normal SIM stays active, so WhatsApp keeps your usual number.
Grace P. · 1 year ago
How do I check how much data I have left?
It is in the app under My eSIMs, and on your account dashboard on the website.
