What is Dual SIM?

The Dual SIM allows you to combine two numbers on one device. This means you can carry your personal and business numbers or two numbers from different countries on the same device. 

It can be presented in two ways:

  • Your device has two SIM slots: you can insert two standard SIM cards and have two numbers simultaneously
  • Your device has only one SIM slot and is eSIM compatible: you can insert a standard SIM card and activate a second number via an eSIM

Not all devices are Dual SIM compatible. In order to know the compatibility of your device you can refer to its technical specifications or consult our list of eSIM compatible devices.
