Questions people ask

What is the best travel eSIM?

For most trips, SimbaSIM. It is the only one here that ticks every box in the comparison: every plan is unlimited data, there is no app or account, days start when you land, more days go onto the same eSIM, the 3, 7 and 14-day plans are the same in all 136 destinations, and you get a full refund if it never connects — plus unused days back within 30 days.

Do I need to download an app for a travel eSIM?

Not with SimbaSIM: you buy on the website and your eSIM is delivered by email in 1 minute, with no account to create. Several brands — Jetpac, Saily and Truely among them — install through their own app, and Maya needs an account and its app to manage the plan.

When does a travel eSIM start counting days?

With SimbaSIM, when you first connect at your destination, so you can install at home and your days are not used up before you land.

What happens if the eSIM never works?

With SimbaSIM you get a full refund if it will not install or never connects — even after you have installed it — and unused days are refunded within 30 days of purchase. Many brands refund only before the eSIM is installed or activated.
