International eSIM by OneSimCard

The OneSimCard eSIM is an electronic, embedded SIM card that offers our super-affordable international data roaming services at 4G/LTE speed without having our physical SIM in the phone. OneSimCard eSIM is delivered instantly online, so there is no need to ship the physical SIM, saving you both time, and the cost of shipping.

The OneSimCard eSIM is fully independent of other OneSimCard global roaming products. However, it offers virtually all of the same blazing fast mobile data services and plans with which you are familiar from OneSimCard. Voice and SMS connectivity will still be delivered through our traditional physical SIM card. OneSimCard eSIM supports several existing devices enabled with eSIM technology, and the list of supported devices will continue to expand.

eSIM Benefits

eSIM allows a compatible phone to essentially become a dual SIM phone working with two sim cards from different providers simultaneously. Devices supporting eSIM and a physical SIM-card, e.g. iPhone XS/XR/XS Max, allow simultaneous operation of the physical SIM card and the embedded SIM – eSIM. From the settings menu of your eSIM enabled phone, you can easily select which SIM card to use at any time, or use one SIM provider for voice and sms and another for mobile data. You in complete control.

An active internet connection (e.g. WiFi or Cellular data connection) is required on the phone while you create a new eSIM account on your phone. To install the eSIM, simply scan the QR code from your online account and follow a few simple steps to finalize the installation.
