simple setup

A quick and relatively easy setup process gets this card activated and ready to use in no time. 

Good to Know Tip: You'll need to enter a phone number to get past the activation screen, but it's not needed to use for verification. Just use an old sim phone number, or a friend or relative's, since it's easy to change later in settings.

Save money

Save your money with affordable pay-as-you-go rates on international voice and data roaming. Don't waste money buying local sim cards, or paying for unsafe or unreliable wifi connections.


Use this sim card to connect to local networks all around the world. Plus the simple rate calculator on the app instantly shows the rates in any country you search for.


And yes, you can even get unlimited data while traveling! What?! Simply choose packages to purchase for low daily rates on data. 

Good to Know Tip: For discount rates, some calls will be routed via a local call-back system, where you'll place a call, disconnect, and then that number will come right back to you as an incoming call. It's virtually instantaneous and doesn't affect your call.
