Top-up is available only on cards that say it is supported. Usage is displayed only when the plan supplies a usable reading; unknown is never rendered as zero.
BEFORE PURCHASE
Three checks first.
Confirm eSIM support for the exact regional phone model.
Confirm that the phone is carrier-unlocked.
Read activation, validity and refund behavior on the exact plan.
Payment confirmation, order creation and eSIM readiness are different events. Your account shows the current state and exposes private installation details only after provisioning succeeds.
What is the current starting price of an eSIM for Japan?
The current catalogue starts at $3.79. MirageTEL rechecks price and availability on the exact plan page before an order is confirmed.
How much data is available for Japan?
Fixed-data and Unlimited plans with daily fair use are available, with validity from 1 to 30 days.
Can I keep my normal SIM?
A compatible dual-SIM phone can normally keep the primary SIM enabled while the travel eSIM is selected for mobile data. Your carrier and phone settings still control charges on the primary line.
Can I add more data to the same eSIM?
Some current plans on this page report top-up support. Open the exact plan to confirm before purchase.
What should I check before buying?
Confirm that the exact regional phone model supports eSIM, that it is carrier-unlocked, and that the plan allowance, validity, activation behavior and refund boundary fit the trip.
