How do I use an eSIM?

Downloadable SIM cards make it easy to get prepaid data in countries all over the world, without roaming charges.


Buy a data package

Choose where you’ll be travelling, how much data you’d like, and how long you need it to last.


Install your eSIM

It takes about two minutes to install your eSIM on a compatible phone or tablet. You’ll need a strong Wi-Fi or data connection for this step.


Activate your package

When you arrive at your destination (or right before you arrive), activate your prepaid data package so your phone can connect to a supported network as soon as it’s available.

Does my phone support eSIM?

Whether you have an iPhone, a Google Pixel, a Samsung Galaxy, or something else, most newer phones already support eSIM and can download new SIMs immediately.

If you’re not sure, we’ll help check your phone to see if it can support eSIM. We’ll also confirm it’s unlocked and allowed to connect to new networks.

What are the eSIM alternatives?

Roaming charges

If you use your phone normally while you’re in another country, you might arrive back home to a very expensive phone bill.

Carrier travel plans

Phone carriers sometimes charge upwards of $16 daily for you to use your phone internationally.

Airplane mode

You won’t pay extra fees when your phone is on Airplane Mode, but you also won’t be able to use data, call, or text.

SIM card swaps

It can be be risky to remove your primary SIM card and replace it with one you bought at an airport kiosk.
