With a dual SIM Windows Phone, you have more choices when it comes to your cellular connection. For example, you can choose which SIM you want to use based on which one has a better price for cellular data or where one cellular network gives you a better signal than the other. A dual SIM phone can also help you keep your work and personal life separate if you want—use one SIM for work and the other for personal, but only carry one phone.
On a dual SIM phone, you'll get two Phone Tiles and two Messaging Tiles on your Start screen, so you can just tap the Tile for the SIM you want to use to call or text.
When you're using a Windows Phone that has dual SIMs, you can name your SIMs to tell them apart on your phone, determine which SIM is used for cellular data, control your data connection speed, and turn off a SIM all together if you want to help avoid unexpected charges on it.
Windows Phones that have dual SIMs are only available for Windows Phone 8.1.
To name your SIM cards
You can name your SIMs to tell them apart on your phone. The name you give each SIM will then appear in different parts of your Windows Phone—including on the Phone Tiles and Messaging Tiles on your Start screen, as well as in Cellular + SIM settings (to name a few).

Under SIM 1, in the SIM name box, type a name for the first SIM, and then press the Backbutton.
Tap SIM 2 settings.
Under SIM 2, in the SIM name box, type a name for the second SIM.
