Frequently asked questions
How much does the Japan eSIM cost?
The Japan 20GB 30Days plan costs $13.12 for 20 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.
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
Yuki V. · 6 days ago
Is there an app to manage the eSIM?
Hi Yuki! Yes — the eSIM TopUp app lets you install the eSIM and keep an eye on your data usage while you're in Japan. You can also top up the same plan right from the app. Any questions, we're at esimtopup.io/support. – Ingrid

Is 5G supported or just 4G?
You get 5G on networks that carry it, and 4G everywhere else. No setting to change.

Great guide, the setup steps were really helpful.
Thank you, that is good to hear.
Noah F. · 4 months ago
Will this keep my WhatsApp active with my home number?
It does — your home number stays live for WhatsApp, calls and texts. The eSIM only carries data.
Lucia B. · 4 months ago
Which networks does this connect to?
The plan page lists the carriers for that destination. Selection is automatic.
Katya K. · 5 months ago
Is roaming charged extra or is it all included?
It is all included. You pay once for the plan and there are no roaming charges on top.
Ethan L. · 6 months ago
Do I need to install it before I travel or after I arrive?
Before — install on Wi-Fi at home. The plan only starts once it connects at your destination.
Ava G. · 7 months ago
Does this work on an iPhone 13?
It does. Every iPhone from the XS onwards supports eSIM, including the 13.

Can I use this for hotspot/tethering?
Yes, you can share the connection with a laptop or another phone.
Emma V. · 1 year ago
Does the validity start on purchase or on first use?
Validity starts on first connection at your destination, not at purchase.
Liam P. · 1 year 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.
Louis H. · 1 year ago
Can I top up the same eSIM instead of buying a new one?
Yes, if the plan supports top-up you can add data to the same eSIM rather than installing a new one.
