Frequently Asked Questions
Most recent smartphones support eSIM, but you should always double-check:
On iPhone: go to Settings → General → About and look for an EID number. If you see EID, your iPhone supports eSIM.
On Android: go to Settings → About phone and look for eSIM, SIM manager, or an EID field.
Your device must also be network unlocked to use an international eSIM.
If you are not sure, you can share your phone model with Gohub support, and we can help you confirm compatibility.
The safest flow is:
Purchase your Japan eSIM 3 to 7 days before departure while you still have stable Wi-Fi and time to read the instructions.
Install the eSIM profile on your phone before you fly, but keep the line switched off.
Activate mobile data only after landing in Japan so your validity period starts at the right time.
This way you land in Japan ready to connect, and you avoid any last-minute stress at the airport.
No. A travel eSIM profile is designed for one device only:
Once an eSIM is activated on a phone, it cannot be reused or moved to another device.
If you change phones or want to use data on a second device, you will need a new eSIM or use a hotspot from the main device.
For families or groups, each person should have their own eSIM or share a connection via hotspot.
Yes. Support is available via the Gohub app and customer service channels.
This depends on how you use your phone, but the ranges below work for most travelers:
Light use (messages, maps, a bit of browsing): about 1 GB per 3 days.
Normal use (social media, map navigation, food searches, some video): around 1 to 2 GB per day.
Heavy use (HD video, streaming music all day, frequent uploads): 3 GB or more per day.
Rough guide:
7 day trip:
Light user: 3 to 5 GB
Normal user: 7 to 15 GB
14 day trip:
Light user: 5 to 8 GB
Normal user: 15 to 30 GB
If you are unsure, choose a plan slightly larger than your estimate so you do not have to worry about running out.
Yes, hotspot is supported on most Japan eSIM plans, as long as:
Your smartphone allows tethering/personal hotspot, and
You stay within the data and fair usage limits of your plan.
Hotspot is a good option if you want to share a connection with a laptop or a partner, but remember that tethering can consume data faster than using the phone alone.
A standard Japan data only eSIM:
Does not include traditional voice calls or SMS.
You can still call and message using apps such as WhatsApp, Messenger, FaceTime, LINE or Zoom over data.
It normally does not support SMS verification for banking or government services, so keep your home SIM if you need those codes.
Some plans may include voice or SMS. Always check the plan details before purchase.
If your Japan eSIM does not connect after landing, try these steps:
Turn on data roaming for the eSIM line.
Set the eSIM as your primary data line in mobile data settings.
Restart your phone and wait a few minutes to search for the local network.
Make sure APN and network selection are set to automatic.
If you changed any settings manually, reset them to default and try again.
If it still does not connect, contact Gohub 24/7 human support via app, email or chat. Share a screenshot of your SIM settings and we can guide you step by step.
