Coverage during your trip
The plans and networks shown below come from the current Flowsus catalog. Coverage can vary in tunnels, on mountain routes, remote islands and rural rail journeys, so keep important tickets and addresses available offline.
Choosing and preparing your plan
Start with the days of your trip, then estimate how often you will use maps, messaging, social media, video or hotspot. A short city break and a longer multi-city journey may need different allowances even when the destination is the same.
Installation
Install the eSIM over reliable Wi-Fi before departure when the plan permits it. Keep the QR code or manual activation details from your order, and confirm that your phone supports eSIM and is carrier-unlocked.
Activation
After landing, select the travel eSIM for mobile data and follow the activation instructions for the selected plan. Keep your primary SIM available for your usual number, calls and SMS if needed.
Before you travel
- Confirm eSIM support and carrier-unlock status
- Choose allowance and validity for your itinerary
- Check hotspot support in the individual plan details
- Save rail, hotel and emergency information offline
Japan eSIM questions
How do I choose an eSIM for Japan?
Compare the current plans by validity, data allowance, price, network details and hotspot policy. Match those details to your itinerary and daily phone habits instead of choosing by the plan name alone.
How much data do I need for a trip to Japan?
Maps and messaging are usually lighter activities than social video, cloud photo backup or hotspot. Use your travel days and expected usage to choose an allowance, then keep key reservations available offline.
Can I install a Japan eSIM before flying?
Often yes when the plan allows pre-installation. Use reliable Wi-Fi, keep the order instructions nearby and check when the plan starts counting validity before you enable it.
