When Does My Data Plan Start? (Validity Policy)

Understand when your eSIM validity period begins and how to maximize your plan duration.

Your Roamiya eSIM plan validity does NOT start when you buy or install it.


πŸ• When Does the Countdown Begin?

The validity timer starts only when BOTH conditions are met:

  1. βœ… The eSIM is installed on your phone.
  2. βœ… Your phone connects to a local network at the destination.

Example:

  • Jan 1: Buy a 7-day Japan eSIM in New York.
  • Jan 5: Install it at home (no timer starts – you're not in Japan).
  • Jan 10: Land in Tokyo, phone connects to SoftBank.
  • Jan 10: ⏱️ Timer starts NOW.
  • Jan 17: Plan expires (7 days later).

πŸ“‹ Key Points

QuestionAnswer
Does installing early waste my days?No. Timer only starts upon network connection abroad.
What if I install but never travel?The eSIM sits dormant. You can request a refund if never scanned.
Multi-country plans?Timer starts when you connect in the first supported country.

🌐 What counts as "activation"?

  • Flying to Japan and your phone locks onto KDDI/SoftBank = Activated.
  • Installing at home and seeing "No Service" = NOT Activated.
