Install & activate

When should I install my eSIM, and when does the plan start?

Quick answer

Install it at home in India on Wi-Fi, a day or two before you fly. Your plan's days only start counting when the eSIM first connects to a network at your destination.

Why install before you fly

  • You need Wi-Fi to install, and airport Wi-Fi can be slow or hard to log in to.
  • If anything goes wrong, you have time to message us.
  • When you land, you just turn the line on.

When does the plan start?

The validity starts when the eSIM first connects to a supported network at your destination. Installing it at home does not start the plan.

Can I install it weeks before?

Yes. Just keep the eSIM line off until you arrive, and do not delete it.

Flying to more than one country? A regional plan covers them all on one eSIM.

Common questions

Does installing the eSIM start my plan?

No. The plan starts when the eSIM first connects at your destination.

Can I install it after I land?

Yes, if you have good Wi-Fi. Installing at home is easier and less stressful.
