When Should I Buy My eSIM? (Validity & Activation)

Don't stress about timing. Learn exactly when to purchase and install your Roamiya eSIM for your upcoming trip.

One of the most common questions we get is: "If I buy a 7-day plan today, does the 7 days start immediately?"

The answer is NO. You can buy safely in advance! 😌


πŸ•’ How Validity Works

The validity "clock" for most Roamiya plans only starts ticking when two conditions are met:

  1. You have installed the eSIM, AND
  2. Your phone connects to a local network in the destination country.

Example Scenario

  • Jan 1: You buy a "7-Day Japan" eSIM while at home in London.
  • Jan 1: You install it on your iPhone. It says "Activating..." then maybe "No Service" (because you aren't in Japan yet). The countdown hasn't started.
  • Jan 15: You land in Tokyo, turn off Airplane Mode, and your phone connects to SoftBank/KDDI.
  • Jan 15: βœ… NOW the 7-day countdown begins.
  • Jan 22: Your plan expires.

To ensure a stress-free trip, we recommend this schedule:

1-4 Weeks Before Trip

πŸ›’ Purchase your eSIM. Get it sorted early so you don't forget. Check your email for the QR code.

1-2 Days Before Trip (or at Airport)

πŸ“² Install the eSIM. Do this while you have a strong, stable WiFi connection (home or office).

  • Scan the code.
  • Label it "Travel".
  • Leave "Data Roaming" OFF for now.
  • It might show "No Service" β€” that's normal!

On The Plane

✈️ Settings Prep.

  • Turn Data Roaming ON for the Roamiya eSIM.
  • Make sure Roamiya is selected for Mobile Data.

On Arrival

πŸ›¬ Land & Connect. Turn off Airplane Mode. Your phone will search, find the local signal, and you'll be online instantly.


❓ Frequently Asked Questions

Can I install it months in advance?

Yes, technically. However, eSIM QR codes typically expire if not scanned within 3-6 months. We recommend buying within 30 days of your trip.

What if my trip is cancelled?

If you bought the eSIM but never scanned the QR code, you are eligible for a 100% full refund within 30 days of purchase. See our Refund Policy.

I'm traveling to multiple countries?

If you bought a "Regional" or "Global" plan (e.g., Europe 33 Countries), the validity starts when you connect in any of the supported countries. It doesn't reset when you cross borders.
