Selected iOS and Android devices feature Dual SIM capability with a nano-SIM and an eSIM. An eSIM is a digital SIM that allows you to activate a mobile plan from M1 without having to use a physical nano-SIM.
Here are some advantages of an eSIM:
- Hold separate voice / data plans on a single device and switch whenever you want to
- Assign and use one number for work and another for personal use
Your device can use one number at any one time.
