How Dual-SIM with eSIM Work

A dual-SIM device has two SIM cards, which could be two nano-SIM cards or one nano-SIM and an eSIM. Newer phones use the nano/e-SIM combination. The Set up may vary from device to device but generally, it is quite a simple process. With both nano and e-SIM combinations, you only have to load the nano-SIM into the phone sim tray since the eSIM is already embedded into the phone. You can buy an eSIM online and scan the QR code or get one from a mobile carrier and do a manual setup to set up the eSIM.

Whichever method you use the result will always be the same which means you will now have two SIMs each with a separate phone number and network connection. With this you can make or receive calls, connect to the internet or send and receive messages on both. The concept may seem the same but not all dual-SIM devices are created equal. Depending on the type of dual-SIM mode your phone uses, you either use both SIMs simultaneously or you will have to choose between them. The 3 dual-SIM modes are Dual-SIM Standby (DSS), Dual-SIM Active (DSA) and Dual SIM Dual Standby (DSDS).
