When does the validity period start for a Sri Lanka eSIM—on purchase, install, or first connection?

I'm planning a trip to Sri Lanka next month and want to buy my eSIM now. Does the validity period begin immediately when I purchase, when I install the eSIM, or only when I first connect in Sri Lanka? I need to know so I don't lose days before I even arrive.

For our Sri Lanka plans, the validity period starts when the eSIM first connects to a network in Sri Lanka, not at purchase or install. So you can buy and install now, and the clock won't start until you arrive and connect.

I bought my Sri Lanka eSIM two weeks before my trip and installed it at home. It activated the moment I landed in Colombo and connected to Dialog. No days were lost.

Same here—installed early, and it only started counting when I turned off airplane mode after landing. Just make sure data roaming is on for the eSIM line.

I installed mine while still at home, and it didn't activate until I connected in Sri Lanka. But I've heard some providers start on install, so always double-check the plan details.

I installed mine at home but didn't turn it on until I was in Sri Lanka. It worked flawlessly and didn't start until I connected to a local network. Just don't manually select a network before you arrive.

To clarify: the validity countdown begins only after the eSIM successfully registers on a Sri Lankan network. You can install it days or weeks in advance without losing any days.

Mine started when I connected in Sri Lanka. I’d suggest installing it before you fly so you’re ready to go as soon as you land.

I waited until I arrived to install mine, and it still started on first connection. Either way works, but installing early saves time at the airport.
