Your Surface Duo supports both physical SIM cards and eSIMs. If your carrier supports it, eSIM makes switching between mobile carriers and data plans really easy. It’s especially useful if you rely on multiple carriers or data plans for different occasions, such as a work and personal plans.
eSIM can be used in conjunction with a physical SIM, or alone. Check out the tutorial below that walks you through connecting to your mobile carrier via an eSIM.
