자주 묻는 질문

Does an eSIM work on the Shinkansen?+

Yes, though long tunnels interrupt it, especially on the stretches that cut straight through mountains. If you need to join an online meeting on board, download the files you need beforehand and leave slack in the schedule; service comes back on its own once the train clears the tunnel or stops at a station.

Do I need an unlimited plan for Japan?+

Usually not. A 10–20GB plan covers a typical 7–10 day trip built around maps, chat and photos. Unlimited pays off when you stream or go live every day, or when you tether several devices off one line. Multiply your realistic daily use by the number of nights before you decide.

Should I turn roaming off on my Thai SIM while using the eSIM?+

Yes. Set the eSIM as the data line and switch data roaming off on your Thai SIM so you are not billed twice without noticing. You can still leave the Thai line registered for calls and SMS if you are waiting on bank one-time passwords, because receiving a text does not draw on the eSIM data allowance.

When does a Japan eSIM start counting days?+

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

Do I have to remove my home SIM?+

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
