When to Install and Activate eSIM (Before vs At Destination)

TL;DR

• Install (profile download) is safest before departure on stable Wi‑Fi.
• Activation (when use starts) depends on the plan. “First connection at destination” = install at home, starts automatically when you arrive.
• “Starts at purchase” or “Starts at install” = validity runs from that moment—don’t install days before the trip.

When to install

• When: Before departure, on stable Wi‑Fi.
• Why: Install needs Wi‑Fi; leaving the screen or closing the app can cause failure.
• Installing at destination is possible but airport Wi‑Fi may be slow or unstable.

When activation starts (by plan)

• At first local connection: Install anytime; period starts when you connect in the destination country.
• At purchase or install: Validity begins immediately—install only when you’re about to use it.

Check your plan’s start condition before installing early.
