How can we help?

An eSIM is a digital SIM built into your phone. There's no plastic card to insert: you install it straight from the email we send you.

It works just like a normal SIM. Once it's installed, your phone connects to one of our partner networks at your destination.

An eSIM is installed digitally from your email, so you get it within minutes. A SIM card is a physical card we deliver to your address, which you insert into your phone. Both give you mobile data at your destination.

Yes. Most eSIM phones can use both at once. Your regular SIM stays in your phone, and the Flash eSIM takes care of your data.

We sell both eSIMs and physical SIM cards for international travel.
